Sonicare Electric Brush

Our review of Sonicare's rechargeable toothbrush lines - A comparison of features, with differences between each line noted.  (Updated November 2019)

- DiamondClean Smart | DiamondClean | FlexCare Platinum Connected | FlexCare+ | ExpertClean | HealthyWhite+ | ProtectiveClean | For Kids | 3 Series | 2 Series | DailyClean | Essence | EasyClean | PowerUp

This page contains an overview of the individual product lines that make up Sonicare's lineup of rechargeable electric toothbrushes.

For each toothbrush line ...

We outline the range of features its models have. Point out how each line is different from, or similar to, others. And give you a bit of opinion about how that line's collection of features stack up as a whole (pros, cons, what makes its brushes unique, and reasons why you would or wouldn't want to purchase one of its models).

Additionally, with each product line's review, we make note of what details you need to know in order to keep things straight when comparing the capabilities of its individual models.

Additional pages you may want to read.

This page has some related companion pages:

  • One is our Best Sonicares page. It walks you through a line of reasoning that can be used to select the best-value models (a combination of features, capabilities and price) out of the Sonicare lineup.
  • And if you're interested, we offer this same type of product line review for Oral-B electric toothbrushes.)

 


What are Sonicare's current toothbrush lines?

We checked Sonicare's (USA) website on November 16, 2019, and found the following product lines listed.

 

The range of MSRPs (manufacturer suggested retail price) for their models ranged from $330 down to just $14, so as you can imagine these lines offer a wide range of bundled features.

Features that Sonicare toothbrush lines all tend to have in common.

Instead of repeatedly describing the same set of features for each of the model lines reviewed below, we'll mention that there tend to be several core characteristics that most/better Sonicares usually share.

We've outlined these features at the bottom of this page. If you're already familiar with Sonicare toothbrushes, you may not need this background information. Also, as additional help, we link to feature details in that section throughout our text below.

Double-check before you buy.

We've gone to a lot of effort in compiling the information found on this page, trying to make sure we got everything right. But even beyond our possible fallibility, it's important to point out:

  • Sonicare promotional materials frequently include the line: "Specifications are subject to change without notice."
  • The Sonicare product lines seem ever in flux with new, differently featured, models introduced throughout the year.

 

So just to play it safe, please do us a favor. Before you buy any toothbrush, double-check what we say you're getting versus what's stated on the packaging or description of the actual product you're planning to purchase. We don't want you to be disappointed.


The Sonicare toothbrush lines -

Characteristic features, similarities and differences.

a) The DiamondClean Smart electric toothbrushes -

This is Sonicare's premier ("best ever" as stated on their website) toothbrush line. It's also their most technologically advanced group of brushes.

Note: When shopping, don't confuse the "DiamondClean Smart" and "DiamondClean" (non-Smart) lines. There are substantial differences in their features.

Prices.

The regular MSRP for DiamondClean Smart brushes ranges from $330 down to $230.
( Compare DiamondClean Smart prices and deals at Amazon.com or Walmart.com using our affiliate links. )

Model numbers associated with this product line: HX9985/01, HX9985/41, HX9985/21, HX9957/61, HX9957/51, HX9957/38, HX9924/91, HX9954/56, HX9924/62, HX9944/12, HX9944/11, HX9924/61, HX9924/41, HX9924/37, HX9924/35, HX9924/21, HX9924/11, HX9924/01, HX9903/61, HX9903/41, HX9903/33, HX9903/32, HX9903/31, HX9903/30, HX9903/21, HX9903/11, HX9903/01

Distinguishing features of the DiamondClean Smart toothbrush line.

  • 4 or 5 brushing modes, depending on the model. (Clean | White+ | Deep Clean+ | Gum Health | TongueCare).

    Lesser models do not have TongueCare mode. (We assign little importance in having it, use the link for more information.)

  • 3 brushing intensity settings (High, Medium, Low). (The Medium and Low settings reduce brushing effectiveness.)
  • BrushSync brushing mode pairing. (When one of Sonicare's microchipped BrushSync brush heads is installed, the toothbrush automatically switches to what Sonicare considers that head's corresponding optimal brushing mode, or else the mode you have previously programmed for that head.)

    (If you believe in the benefit of using Sonicare's various brushing modes, and that a brush head's design helps to optimize that mode's effectiveness, then you'll like this feature.

    If instead you feel that just using your brush in its full-power mode is the most beneficial one, and want a full choice of which style of brush head you use when you do, you'll find this feature to be a nuisance.)

 

  • Integration with Sonicare's smartphone app. (App includes mouth-map and touchup reporting.)
  • Smart Sensor Technology: Brushing pressure sensor, location sensor, scrubbing sensor, brush head replacement indicator.

    (Microchipped BrushSync brush heads allow the toothbrush handle to monitor these various factors and report to you about them via brush handle features (lights, vibrations) and Sonicare's smartphone app.)

  • A travel case that can be used as a charging station. (Higher-end models only.) (The case requires a USB connection for charging operations.)
  • Additional replacement toothbrush heads are included (1 up to 7), depending on the model.

 

Additional DiamondClean Smart features.

 

What we feel you need to know about the DiamondClean Smart toothbrush line.

It's a quality brush ...

As Sonicare's top line, it's a given that the DiamondClean Smart models are good toothbrushes. And we think that it's accurate to say that with Sonicares, a higher price generally does correlate with superior product design and build refinement.

We're not really so sold on this collection of features ...

It seems to us that much of what this toothbrush line offers is fairly frivolous (multiple brushing modes, multiple brushing intensities, BrushSync brushing mode switching). That opinion is biased by the fact that we think that the vast majority of users are best served by just using full-intensity Clean mode (the constant 62,000 brush movements/minute Sonicare brushing action).

If you're not of that opinion, then this line's 15 brushing mode configurations (12 on lesser models) may be quite attractive to you.

The smartphone brushing app ...

We primarily view the Sonicare brushing app as a "brushing behavior" feature. Its primary function isn't so much to modify the function of the brush but instead to help you modify your brushing behavior, so you use the brush more effectively.

So in situations where a person using the brush needs this type of assistance, then this line can be a good choice. We will point out however, app integration is also available with some less expensive Sonicare lines.

For people who are already effective brushers, and already have the motivation to perform that task, buying a less expensive model that doesn't feature app integration would seem to make a more cost-effective choice.

Bottom line ...

If you want the collection of features that the DiamondClean Smarts offer, then we think this is a fine toothbrush line to buy.

But in terms of purchasing a brush that just has those vital core features we think are necessary to have, or even, just the ones that you're likely to still be using after the newness of your brush has worn off, we think you can get everything you need by purchasing other Sonicare models that have a lower price. (This is a major premise of our Best Sonicares page.)

If you're considering the DiamondClean Smart line.

Keeping the models straight ...

Pay specific attention to how many replacement brush heads you'll get. And after deciding if they're important for you, if the brush's travel case has the USB charging feature, and if a fifth brushing mode (TongueCare) is included.


b) The DiamondClean electric toothbrushes -

This is the less technologically sophisticated branch of the DiamondClean line, and as such its models lack the high-tech capabilities of the DiamondClean Smarts.

Prices.

The regular MSRP for the DiamondClean line of toothbrushes ranges from $250 down to $200.
( Compare DiamondClean prices and deals at Amazon.com or Walmart.com using our affiliate links. )

Model numbers associated with this product line: HX9372/04, HX9352/04, HX9332/05, HX9363/81, HX9393/82, HX9392/05, HX9391/90, HX9371/71, HX9361/69, HX9351/57, HX9331/43, HX9362/47

Distinguishing features of the DiamondClean toothbrush line.

  • 5 brushing modes (Clean | Gum Care | Sensitive | White | and a fifth mode, Deep Clean or Polish, depending on the model).
  • (Note: This line does not feature brushing intensity settings.)
  • Some models offer a travel case that can be used as a charging station. (The case requires a USB connection for charging operations.)
  • Additional replacement toothbrush heads are included (1 up to 5), with some models.

 

Additional DiamondClean features.

  • Utilizes click-on brush heads.
  • Features Sonicare's hallmark 62,000 brush movements/minute brushing action.

    (Brush setting: Clean mode.)

  • Easy-Start, SmarTimer, QuadPacer.
  • Glass charger. Lithium-ion battery. Operates "up to 3 weeks" on a full charge.
  • Sample promotional leaflet: DiamondClean toothbrush.

 

What we feel you need to know about the DiamondClean toothbrush line.

This is a quality brush ...

As stated above, it's our impression that more expensive Sonicare brushes typically do have a more refined design and higher build quality.

However, we'll also state that we haven't found that those characteristics entirely correlate with product reliability and/or longevity. So purchasing a Sonicare at these lofty prices is still a bit of a gamble.

Less may be more ...

We can certainly see how this "old school" line's lack of features (no smartphone brushing app integration, no BrushSync mode switching or Smart Sensor tracking and reporting), and the cost-savings this represents, might make this brush comparatively more attractive to some people.

We'll also point out that the lower-tech Sonicares don't require that you purchase the more expensive microchipped (BrushSync) brush heads for them to function fully.

Even so, this brush is still jacked with an excess of features ...

Although this brush doesn't have intensity settings, it still features 5 brushing modes.

Bottom line ...

Take a close look at this toothbrush's features and form an idea of what portion of them you really think you'll end up using over the long-term. Then look at the other brushes on down this page. You'll probably find everything you want in a less expensive model.

If you're considering the DiamondClean line.

Keeping the models straight ...

Note how many additional brush heads are included. If the travel case has charging capabilities or not. And whether the included fifth brushing mode is Deep Clean or Polish.


c) The FlexCare Platinum Connected electric toothbrushes -

This is another high-tech Sonicare toothbrush line.

Prices.

The regular MSRP for FlexCare Platinum Connected toothbrush line ranges from $220 to $200.
( Compare FlexCare Platinum prices and deals at Amazon.com or Walmart.com using our affiliate links. )

Model numbers associated with this product line: HX9193/04, HX9192/02, HX9192/01

Distinguishing features of the FlexCare Platinum Connected line.

  • 3 brushing modes (Clean | White | Deep Clean).
  • 3 brushing intensity settings (High, Medium, Low).
  • Note: This line does not feature BrushSync brushing mode pairing.
  • Integration with Sonicare's smartphone app. (Includes mouth-map and touchup reporting.)
  • Smart sensor technology: Brushing pressure sensor, location sensor, scrubbing sensor, brush head replacement.
  • Additional replacement toothbrush heads are included (1 or 2), depending on the model.
  • One model features a UV brush head sanitizer. (We don't find a need for this option, use the link for information.)

 

Additional FlexCare Platinum Connected features.

  • Utilizes click-on brush heads.
  • Features Sonicare's hallmark 62,000 brush movements/minute brushing action.

    (Brush setting: Clean mode, High intensity.)

  • Non-charging travel case.
  • Easy-Start, SmarTimer, BrushPacer.
  • Traditional charging base. Lithium-ion battery. Operates "up to 2 weeks" on a full charge.
  • Sample promotional leaflet: FlexCare Platinum Connected toothbrush.

 

What we feel you need to know about the FlexCare Platinum Connected toothbrush line.

This is a quality brush ...

As stated above, there seems to be a benefit in purchasing a higher-end vs. lower-end Sonicare in terms of design, refinement and build. And we definitely consider this line to fall into the high-end category. In fact, the FlexCare name is a top line of yesteryear.

This is another techie model ...

With the FlexCare Platinum Connected line, we've returned to Sonicare's realm of high-tech toothbrushes.

This line is similar to the DiamondClean Smarts, in the sense that its toothbrushes integrate with the smartphone brushing app and have Smart Sensor tracking and reporting. So if you want those features, here's another chance.

We will point out that this line does not perform BrushSync brushing mode pairing. (Of course, if you feel it's important to match your brushing mode with the brush head you're using, you can always just do that manually.)

The UV brush head sanitizer ...

Some models of the FlexCare Platinum Connected line feature a UV sanitizer. We're not fans of this option for what we feel are solid scientific reasons. The link above explains.

Bottom line ...

We don't have a lot to say. This is simply a high-end, high-tech Sonicare toothbrush that's loaded up with 9 brushing mode configurations. And it's lower-tech in the sense that it doesn't offer the BrushSync brushing mode pairing option. And if that's the collection of features you want, then we wouldn't hesitate to buy any one of these models.

If you're considering the FlexCare Platinum Connected line.

Keeping the models straight ...

Know if the model you're considering includes a UV brush head sanitizer or not. And note how many additional brush heads are included.


d) The FlexCare Platinum electric toothbrushes -

This is the low-tech (non-connected, non-smart) version of the FlexCare Platinum line.

Prices.

The regular MSRP for the FlexCare Platinum toothbrush line ranges from $200 down to $180.
( Compare FlexCare Platinum prices and deals at Amazon.com or Walmart.com using our affiliate links. )

Model numbers associated with this product line: HX9172/15, HX9112/12

Distinguishing features of the FlexCare Platinum line.

  • 3 brushing modes (Clean | White | Deep Clean).
  • 3 brushing intensity settings (High, Medium, Low).
  • Brushing pressure sensor.
  • 1 additional replacement toothbrush head is included.
  • One model features a UV brush head sanitizer.

 

Additional FlexCare Platinum features.

  • Utilizes click-on brush heads.
  • Features Sonicare's hallmark 62,000 brush movements/minute brushing action.

    (Brush setting: Clean mode, High intensity.)

  • Easy-Start, SmarTimer, QuadPacer.
  • Non-charging travel case.
  • Traditional charging base. Lithium-ion battery. Operates "up to 3 weeks" on a full charge.
  • Sample promotional leaflet: FlexCare Platinum toothbrush.

 

What we feel you need to know about the FlexCare Platinum Connected toothbrush line.

This is a quality brush ...

As stated above, the FlexCare line is a top one from previous years. We consider these brushes to be a solid choice.

It's another model that's loaded up with features ...

Considering our stance about the value of using Clean mode (at High intensity) vs. all other Sonicare brushing configurations, the fact that this brush offers 9 brushing options is a moot point for us.

The UV brush head sanitizer ...

As mentioned above, this isn't an option we would feel is important to have.

Bottom line ...

This is a good Sonicare line but it still offers more toothbrush options (and a higher price) than we feel a person needs. (We elaborate more about this opinion in our Best Sonicares rundown.

If you're considering the FlexCare Platinum line.

Keeping the models straight ...

The only option you need to keep straight among models is whether or not you intend to buy one that has a UV brush head sanitizer.

e) The FlexCare+ electric toothbrushes -

This is one of Sonicare's higher-end brush lines from yesteryear.

( Compare FlexCare+ prices and deals at Amazon.com or Walmart.com using our affiliate links. )

Model numbers associated with this product line: HX6921/04

  • 5 brushing modes (Clean | Gum Care | Refresh | Sensitive | Massage).

  • Sample promotional leaflet: FlexCare+ toothbrush.

 

What we feel you need to know about the FlexCare+ toothbrush line.

This is a quality brush ...

Even at this point in our list, we still consider this to be a higher-end Sonicare line and therefore reasonably well designed and built.

Bottom line ...

If we bought this brush, we'd be happy with it. But considering what portions of its features we would actually use, there are brushes lower on our list that would make a more cost-effective choice.

If you're considering the FlexCare+ line.

Keeping the models straight ...

There's currently only one model, so there are no feature differences to note.


f) The ExpertClean electric toothbrushes -

This is a relatively new high-tech Sonicare line.

Prices.

The regular MSRP for the ExpertClean toothbrush line is $150.
( Compare ExpertClean prices and deals at Amazon.com or Walmart.com using our affiliate links. )

Model numbers associated with this product line: HX9610/17

Distinguishing features of the ExpertClean line.

  • 3 brushing modes (Clean | Gum Health | Deep Clean+).
  • 3 brushing intensity settings (High, Medium, Low).
  • BrushSync brushing mode pairing.
  • Integration with Sonicare's smartphone app. (Evidently no mouth-map or touchup reporting.)
  • Smart sensor technology: Pressure sensor, location sensor, scrubbing sensor, brush head replacement indicator.
  • Includes 1 additional replacement brush head.

 

Additional ExpertClean features.

  • Utilizes click-on brush heads.

    (Brush setting: Clean mode, High intensity.)

  • Non-charging travel case.
  • Easy-Start, SmarTimer, BrushPacer.
  • Traditional charging base. Lithium-ion battery. Operates "up to 2 weeks" on a full charge.
  • Sample promotional leaflet: ExpertClean toothbrush.

 

What we feel you need to know about the ExpertClean toothbrush line.

So far so good ...

When we first became aware of this brush we were a bit leery. In the past Sonicare has introduced some price-point clunkers into its lineup. But when looking through online user reviews about the ExpertClean, so far it seems that people are as satisfied with their purchase as any other Sonicare line.

The app evidently isn't as robust ...

Probably the most-mentioned disappointment in reviews was that the brush/app integration didn't offer the mapping/touchup reporting that the higher-end high-tech models do.

As confirmation, we looked through Sonicare's documentation about the ExpertClean. It does state that the brush features a location sensor. But nowhere did we find mention of the brush having touchup or mouth-map reporting.

With Sonicares, you get what you pay for ...

In a single online review, we noticed that the person stated that they considered that they felt more of their brush's vibration in its handle than with their DiamondClean. And that seems reflective of what we've mentioned above about how design and build quality seems to lessen as you go lower into the Sonicare lineup.

It's our general opinion that:

  • This loss in refinement first starts to become evident in the neighborhood of $150 to $100 (MSRP) price level in the Sonicare lineup.
  • It's typically just noticeable to those who have previously owned a higher-end model, as opposed to new-to-Sonicare owners.
  • While detectable (to some), the loss in refinement doesn't seem to pose a significant detriment to the person's brushing experience.

 

Bottom line ...

If this line's features are what you're looking for, including the app's lack of features noted above, this seems a reasonable brush to buy. It's not a Cadillac (like the DiamondClean Smart or FlexCare Platinum Connected lines) but it still seems to be a suitable brush line.

If you're considering the ExpertClean line.

Keeping the models straight ...

There's currently only one model, so there are no feature differences to note.


g) The HealthyWhite+ electric toothbrushes -

Prices.

The regular MSRP for the HealthyWhite+ toothbrush line is $120.
( Compare HealthyWhite+ prices and deals at Amazon.com or Walmart.com using our affiliate links. )

Model numbers associated with this product line: HX8911/02

Distinguishing features of the HealthyWhite+ line.

  • 2 brushing modes (Clean | White).
  • 3 brushing intensity settings (High, Medium, Low).
  • (Note: No dedicated brushing pressure sensor.)
  • No additional replacement brush heads are included.

 

Additional HealthyWhite+ features.

  • Utilizes click-on brush heads.
  • Features Sonicare's hallmark 62,000 brush movements/minute brushing action.

    (Brush setting: Clean mode, High intensity.)

  • Non-charging travel case.
  • Easy-Start, SmarTimer, QuadPacer.
  • Traditional charging base. Lithium-ion battery. Operates "up to 3 weeks" on a full charge.
  • Sample promotional leaflet: HealthyWhite+ toothbrush.

 

What we feel you need to know about the HealthyWhite+ toothbrush line.

We've liked this brush for a while ...

We've considered the HealthyWhite+ a good-value purchase for a number of years now. (In our Best Sonicares rundown.)

As compared to the brushes above, and reflected in its price, this line comes with a relatively small number of superfluous features. And it lies at a level in the Sonicare lineup (the low end of the higher-end brush lines) that, while not super-refined, is still a reasonable brush.

Brushing modes vs. intensity settings.

One thing about the HealthyWhite+ line is that it has fewer brushing modes but still retains intensity settings.

We can envision scenarios where a brush might be shared with someone who can't tolerate full-power Clean mode (like a debilitated, elderly or young person). However, even this relatively inexpensive brush (and some of the ProtectiveCleans below too) could still accommodate this expanded range of applications due to its intensity options.

Bottom line ...

We think this brush makes a good low-tech Sonicare choice. And it has a price where if the brush dies prematurely, it doesn't sting quite so much.

This latter statement is a reflection of our opinion that in an era of lowest-cost manufacturing and planned-obsolescence design, all powered toothbrushes at any price level (including all of the major brands), are just unpredictable temporary devices.

If you're considering the HealthyWhite+ line.

Keeping the models straight ...

There's currently only one model, so there are no feature differences to note.


h) The HealthyWhite electric toothbrushes -

Prices.

The regular MSRP for the HealthyWhite line is $120 down to $90.
( Compare HealthyWhite prices and deals at Amazon.com or Walmart.com using our affiliate links. )

Model numbers associated with this product line: HX6732/33, HX6721/45

Distinguishing features of the HealthyWhite line.

  • 3 brushing modes (Clean | Clean & White | Sensitive). The lesser model doesn't have Sensitive mode.
  • (Note: This line does not feature brushing intensity settings.)
  • (Note: No dedicated brushing pressure sensor.)
  • One model includes an additional replacement brush head.

 

Additional HealthyWhite features.

  • Utilizes click-on brush heads.
  • Features Sonicare's hallmark 62,000 brush movements/minute brushing action.

    (Brush setting: Clean mode.)

  • Non-charging travel case.
  • Easy-Start, SmarTimer, QuadPacer.
  • Traditional charging base. Lithium-ion battery. Operates "up to 3 weeks" on a full charge.
  • Sample promotional leaflet: HealthyWhite toothbrush.

 

What we feel you need to know about the HealthyWhite toothbrush line.

We haven't seen this brush for a while ...

When we started our update of this page, we were surprised to see some toothbrush lines that we thought had been discontinued brought back from the dead. This is one of them.

Just like with the HealthyWhite+, this line comes with a minimum of features and a comparatively low price. And once again, while not super-refined, a reasonable brush.

Clean and Sensitive mode ...

Although less versatile, the HealthyWhite model that features Sensitive mode might also offer a relatively low-cost solution for the same type of lower-intensity applications mentioned above with the HealthyWhite+.

Bottom line ...

Like its sister toothbrush line, we think this one makes a reasonable low-tech Sonicare choice.

If you're considering the HealthyWhite line.

Keeping the models straight ...

There are currently two models available. The lesser one does not feature Sensitive mode and does not come with any additional brush heads.


i) The ProtectiveClean electric toothbrushes -

The features of the different ProtectiveClean toothbrushes vary widely, so if you're considering one of them, pay a lot of attention to what's included with the models you're looking at.

Prices.

The regular MSRP for the members of the ProtectiveClean toothbrush line is $170 down to $50.
( Compare ProtectiveClean prices and deals at Amazon.com or Walmart.com using our affiliate links. )

Model numbers associated with this product line: HX6481/13, HX6481/12, HX6481/11, HX6877/21, HX6876/21, HX6871/49, HX6871/41, HX6857/11, HX6850/60, HX6817/01, HX6815/01, HX6810/50, HX6463/50, HX6462/05

    4100 - 1 brushing mode (Clean).

    6100, 5100 - Non-charging travel case.

    4100 - No travel case.

  • Some models come with additional replacement toothbrush heads (1 or 2).

 

Additional ProtectiveClean features.

  • Features Sonicare's hallmark 62,000 brush movements/minute brushing action.

    (Brush setting: Clean mode. Models that have intensity settings must be set to High.)

  • Easy-Start, SmarTimer, QuadPacer.
  • Traditional charging base. Lithium-ion battery. Operates "up to 2 weeks" on a full charge.
  • Sample promotional leaflet: ProtectiveClean toothbrush.

 

What we feel you need to know about the ProtectiveClean toothbrush line.

What a curious collection of models ...

As opposed to most Sonicare lines whose brushes tend to share a set of core features, many of the ProtectiveClean models seem almost unrelated. (So pay attention when comparing.)

What a range of prices ...

This line is also unique in the fact that its highest-end model costs over 3 times more than its lowest-end one.

We bring this up because, as mentioned above, as you drop further and further down into the Sonicare lineup, we feel that the design and build quality of the toothbrushes increasingly suffers. (Which is really just a way of saying that "you get what you pay for," which only makes sense.)

That makes us a little bit leery ...

Based on that premise, we feel that we'd be more inclined to buy a 6500, 6100 or possibly even a 5100 model over the bottom-end 4100. However, the statistics associated with online reviews on retailer websites seem to suggest that 4100 owners tend to be quite happy with their choice, even as compared to other Sonicare lines.

But like mentioned above, we would anticipate that it's new-to-Sonicare owners who are the ones who are so favorably impressed by the 4100, as opposed to people who have previously used a (more refined) high-end Sonicare.

The cost of owning this brush ...

We need to point out that for all features to fully function, the ProtectiveClean brushes need to be used with Sonicare's more expensive BrushSync (microchipped) brush heads.

So you should decide how important the set of BrushSync features the model you are considering are to you. And if they're really not, choose from another lower-tech Sonicare line, or just forgo these features by not using BrushSync heads.

Bottom line ...

This seems a reasonable group of models to consider, although we would personally lean toward the higher-end models.

If you're considering the ProtectiveClean line.

Keeping the models straight ...

More so than with other lines, the ProtectiveCleans offer a very wide range of features, so pay attention to what you're getting.

Differences that you must pay attention to include: Brushing modes, intensity settings, BrushSync features, if a travel case is included and if it has charging capabilities, and the number of included replacement brush heads.

Model numbers associated with this product line: HX6351/41, HX6321/02, HX6352/42

Distinguishing features of the For Kids line.

  • Comes with an assortment of interchangeable stickers that can be applied to the brush for decoration.

What we feel you need to know about the ProtectiveClean toothbrush line.

This could be used as a family brush ...

Since this is another one of Sonicare's lines designed to use their click-on brush heads, the For Kids can be used with the full range of Sonicare's "adult" click-on heads too. And that means it could be used as the shared electric toothbrush for all members of a family.

Note: Adults may find the KidTimer and QuadPacer features of this brush annoying.

If you're considering the Sonicare For Kids line.

Keeping the models straight ...

Take notice of how many replacement brush heads are included.


k) What about the even lower-end Sonicare toothbrush lines?

2 Series plaque control, 3 Series gum health, DailyClean, Essence, EasyClean, PowerUp

At this point in our review of the Sonicare lineup, we hit an impasse. Namely, the Sonicare (USA) website.

While using it to perform the research needed to compose this page, we finally concluded that we didn't feel we could trust the accuracy of the information it reported. Most specifically, we felt unsure about what is stated about the brushing actions of some of the lower-end toothbrush lines.

31,000 vs. 62,000 movements per minute.

It would be our opinion (explained here) that the only reason to buy a Sonicare toothbrush is to get it's full-power, 62,000 brush movements-per-minute brushing action. And compared to any other Sonicare models that do have this feature, we consider those that don't to be subpar and simply not worthy of purchase.

Does that mean we feel that 31,000 movement-per-minute Sonicare toothbrushes are bad products?

No, not necessarily. One of these models might make a preferable choice over some other brand's product that also offers a similar or even lower-quality brushing action. But as compared to other Sonicare models, we don't respect these brushes. And for that reason, it doesn't bother us not to include details about them on this page.

Who's right, the Sonicare website or us?

We don't know for sure. But what we do know is that some toothbrush lines that for years on end before had been stated by Sonicare as having the full-power action (historically worded by Sonicare as 31,000 brush-STROKES-per minute) are currently reported on their website as only offering the 31,000 brush-MOVEMENTS-per minute, which is an entirely different action (it's half the frequency).

Possibly Sonicare redesigned all of these toothbrush lines?

Absolutely, they could have. Or this could just be a wording error they have made and have yet to pick up on. We don't know.

What if you want to consider one of these lines?

We would feel that it would be imperative to confirm, via the product's packaging, that it does feature a 62,000 brush-movements-per minute brushing action. If you can't tell that it does, or if it doesn't, we would be inclined to purchase a different model.


Features that Sonicare toothbrush lines typically/frequently share.

As promised at the beginning of this review, here's background information about many of the features that Sonicare lines often have in common.

a) Full-power brushing mode.

The single most important feature to look for in a Sonicare is to note that it's able to produce their hallmark "62,000 brush movements-per-minute" brushing action.

Is this something new?

Long-time users are probably more familiar with seeing Sonicare describe their brushing action as the equivalent "31,000 brushstrokes/minute," which would seem to be a lesser mechanism.

But contrary to what you might initially think, there's nothing new here. Sonicare is just putting a new spin on their original brushing motion. Using their revised math, two brush movements (once up and then once down) = one brushstroke (a combined up and down motion). It's only the terminology that's new.

Sonic toothbrushes can clean beyond where their bristles touch.

Animation showing the fluid-dynamics cleaning action of a Sonicare toothbrush.
How important is this?
  • It's vital. This is the brushing action that delivers a Sonicare's maximum brushing effectiveness. And it's the one that Sonicare built their reputation on in scientific studies and published literature.
  • Their brushes that don't produce a 62,000 movement/minute brushing action can't provide the same level of cleaning effect.
What to look for.

On nearly all Sonicare models it's "Clean" mode that produces their constant full-power 62,000 movements/minute brushing action. If the brush has Intensity settings, High needs to be selected.

How important is it to have other Sonicare brushing modes?

We are of the strong opinion that this full-power mode is the only setting that the vast majority of brush owners need to or should be using.

It's our stance that the use of this mode alone meets or exceeds whatever might be accomplished using any other settings (especially in terms of brushing efficiency and effectiveness). And for this reason, and although all higher-end models feature them, we place essentially no value on a Sonicare brush having additional "novelty" modes.

 

b) Click-on brush heads.

The Sonicare product line has finally reached a point where all but its very, very lowest-end models utilize their click-on (snap-on) brush heads.

How important is this?

This is a very significant feature because it gives you the freedom to select from Sonicare's entire lineup of click-on heads (which is substantial) when choosing replacement brush heads for your brush. You're not just limited to the style it originally came with.

Note.

For this reason, when comparing toothbrush lines and models we place no emphasis on which type(s) of brush head a model comes with. Remember, these are just disposable items that you'll be replacing soon enough. (Sonicare recommends every 3 months).

 

As you read on ...

This next section lists features that most Sonicare toothbrush lines do share, and as such you should be aware of them. However, we assign no overwhelming importance to having any of them.

c) Lithium-ion battery.

Sonicare's toothbrush lines come with either a lithium-ion or NiMH rechargeable battery.
  • Lithium-ion technology has more favorable recharging characteristics and therefore is the more desirable type.
  • Also, those models that feature them tend to have a smaller, sleeker (less bulky) body style.
(More details about Sonicare toothbrush batteries.)

d) 110 - 220V charging.

The primary charging units that come with Sonicare rechargeables are designed to operate with either 110 or 220-volt electrical sources, a point that could be important for world travelers.
(More details about Sonicare charging units.)

e) Smartimer / KidTimer.

All Sonicares feature some type of brushing timer. In most cases, they run for 2 minutes but on some mo, els this vari, s according to the brushing mode being used.

(More details about Sonicare brushing timers.)

f) QuadPacer / BrushPacer

BrushPacer is a beep-and-pause signal that reminds you when to move on to brushing other sections of your mouth. It also integrates with the Sonicare smartphone app. Its precise settings vary according to which brushing mode has been selected.

QuadPacer can be thought of as the non-Smart near-equivalent of BrushPacer. It divides SmarTimer's 2-minute duration 4ths, therefore signaling when you should switch to brushing the next quadrant of your mouth.

g) Easy-start.

This is an introductory brushing mode that gradually builds up its intensity over a consecutive number of brushing sessions, so to help you get used to the sensation of using your brush.

(More details about Sonicare's Easy-start function.)

h) Brushing pressure sensing.

When excessive force is used, the brushing motion of all Sonicare toothbrushes tends to stall. Beyond that, some product lines feature dedicated excessive brushing pressure sensors. Depending on the model, they signal their warning via a light on the toothbrush handle, changes in the toothbrush's vibrations, and/or the smartphone app.

More details about Sonicare brushing pressure indicators.)

I) Smart Sensor Technology

Some higher-tech Sonicare lines feature the following types of Smart Sensor feedback/reporting. Depending on the model, this information is brought to the user's attention via brush handle indicator lights, brush handle vibrations and/or the brush's associated smartphone app.

For these features to work, the toothbrush must have one of Sonicare's (more expensive) microchipped BrushSync brush heads installed.

  • Pressure sensor: Monitors if excessive brushing force is being used.
  • Scrubbing sensor: Detects if you're using too much motion with your brushing technique.
  • Location sensor: This sensor tracks information about the activity that occurs during your brushing session. With the most advanced models, it provides mouth mapping and touchup (missed areas) reporting.
  • Brush head replacement reminder: Based on information collected from brushing sessions (duration and pressure used), a signal (via indicator light and/or smartphone app) advises you when you should replace your current brush head.

 


Still need help in deciding?

We've mentioned throughout this page that we have a Best Sonicares Page. You should give it a read.

On it, we explain our thinking in how to weed through all of Sonicare's features to arrive at a selection of models that can be expected to deliver all of the brushing effectiveness that you need, at the lowest possible brush cost.

Is Sonicare really that good?

My Sonicare just died. It was a good brush except for the fact that it didn't last very long. Do other people complain about this? I'm looking at these prices and wondering if it's really worth it.

Did you call Sonicare?

Reliability is a hard thing to judge. We consider Sonicare and Oral B to be reputable manufacturers but don't have any hard statistics to back that up.

We've read some pretty interesting user reviews where Sonicare owners called the company and told them their complaints (evidently politely). And as a result had their broken units unexpectedly replaced, evidently for free. It's worth a try. It seems if the customer has a legitimate complaint that Sonicare listens (at least sometimes).

If you want to consider an Oral-B instead, we have a whole section on them that could help you get started picking one out.
Good luck. Report back if you don't mind.

they all die pretty fast

2 of my Philips brushes died after 1.5 years of use. Water gets inside them....

POOR Quility POOR company service

We have owned many sonicare toothbrushes in the past. All USED to be a very good product. I think they have tighten their belt and outsourced to the CHEAPEST manufacturer possible. Being a dental professional we USED to buy these in numbers and use as giveaways/promotional to patients. This is NO LONGER the case. They are a piece of junk now. Had problems with the "new" brush head falling off. I was basically told your problem.. NO, not my problem any longer. I attend many dental meeting with other dentist. I have been a one man wrecking crew telling my story.. I WONT EVER recommend the Phillips Sonicare to ANYONE again. I hope you will boycott this product too.

Thank you!

I have been using the Sonicare Essence for many years now. My first one lasted about 8 years before it finally stopped holding a charge. Got a new one and it died within warranty so they replaced it, no charge to me, with the same model but it had the quad pacer, which my broken one did not have. It's still working fine after 3 years but I am looking at getting the Series 3 as I was told my gums are getting "soft". I had been looking at the more expensive models but thanks to your information I see I'd be paying for things I wouldn't really be needing or using. Thanks for saving me some $$ that will be put towards dental visits for replacing ancient fillings! I appreciate all the information I found here-thank you!

Thanks for posting Laura.

Thanks for posting Laura. Thanks for mentioning your experience with Sonicare and how their replacement policy worked out for you.

Your information couldn't

Your information couldn't have been more helpful. Terrific research. Saved me $110 !!!
Thanks so much!!

This site is a gem

My wife had an ancient Essence type Sonicare brush which she wanted to replace. In checking the current Sonicare product line we were baffled by all the various Sonicare models, brush heads and features. Then your wonderful web site came to the rescue, cleared away all the verbiage and made it crystal clear what characteristics are the important ones. As a result my wife bought a simple Series 2 brush on sale which we are sure will suit her needs. Thanks for your help!

HX6970 versus HX6960

Has anyone noticed or is it factual that the HX6970 black Philips is more powerful than HX6960? I was sent a replacement for one of my Black HX6970 handles (two in the set with charger from Costco) The white replacement HX6960 seems far less powerful. I was thinking of sending it back and asking for a replacement of my exact model if there is a power difference . Is it just me or is there an actual difference in power? It seems to be not as intense of brushing on the identical "clean" setting and the other settings are worthless and it's missing the max and go care.

VLC

The model numbers HX6970 and HX6960 don't appear in the current line up of Sonicares on their official site but generally speaking the HX69 portion of a number typically indicates a FlexCare+ model. That's a relatively higher-end Sonicare. At one time it was the top of the line model.

Model numbers that close together (70 vs. 60) typically does just indicate a very minor difference, such as color. It would be our expectation (unless you noticed something on the packaging that indicated differently) that the two brushes would be pretty much identical mechanically.

We wonder if the replacement brush you received is a "refurbished" one, and while mechanically functional not truely up to snuff.

Excellent

Your site provided excellent information on the various (way too many) models available. Using your review I think I made a good choice while replacing four old Sonic models - and you saved me money too. Thank you!

AA Battery powered model discontinued

The original battery powered unit I have using AA batteries cleans at 31,000 strokes. I can't seem to find a replacement. What happened? This power up model is sluggish and doesn't seem to do as good a job at cleaning. Why doesn't Sonicare produce the better quality AA battery powered model any longer? When trveling the charging model is toast.

JT

We remember the Sonicare Xtreme, and like you suggest, since it used off-the-shelf AA batteries a fresh charge was always possible, no matter where your were.

We assume you've read what we state about the PowerUp above (it's a 15,000 brush not a 31,000 one) and how we don't think it makes an acceptable choice.

The rechargeable Sonicares that would be better at sustaining a charge are the lithium ion battery models. We show "operating time" estimates above.

Are the New Models Weak?

It was finally time to retire my original Sonicare. I think its an A-Series (I cut it open and replaced the batteries). I got an Essence+ and Adaptive Clean brush heads. It was very underwhelming, the old Sonicare feels like a jack-hammer compared to the new one.

Its fully charged and the easy start is turned off. I tried the brush head supplied with the Essence+ and it feels a little stronger but still not as good as the old.

I tried placing the old and new in a bowl of water and turning them on. There is absolutely no comparison.

Did I happen to get a dud or are they really just weaker?

Thanks!

Rob

Sonicare's trend ever since the Elite replaced the A-series has been toward smaller, lighter brush heads, which require a less powerful motor to create their brushing action.

In fact, we ran across a web page that described rigging Elite heads to work on A-series handles. And it describes how much more powerfully that smaller head is driven when that is done. So the reduction in power (level of agitation) is by design, and should not necessarily be confused with the brush's inability to clean effectively (plaque is a soft substance and harsh scrubbing isn't required to remove it).

As side from that, and as we describe elsewhere on our pages, higher-end Sonicare products tend to have "stronger" motors. A difference that is most noticed by previous Sonicare owners when buying economy models.

Yup, I have been using E

Yup, I have been using E-Series brushes on the old handle. I'll read through the pages again to see how much I have to spend for a stronger one. I called Sonicare and was told they all have the same power but the customer service agent probably was confusing power with frequency.

I have some small accelerometers and am tempted to actually measure the difference between the old and Essence+ and the one I try next. But like you said, it only need to be strong enough to do the job.

Thanks

Rob

Rob

After you go through your investigation please post again.

We're not so sure your expectation of the experience of an e-series head running on an a-series handle is a realistic one. That was never a configuration Sonicare intended (sold as a toothbrush unit).

Generally speaking, the Healthywhite+ seems to us to be the low end of the more powerful Sonicares. Although most people seem to notice a difference in power between that level of brush and the DiamondClean (for example). It just gets to a point where you have to decide how much you are going to spend on one of these devices.

It is the brush frequency that has to do with the brush's "sonic" cleaning abilities (cleaning beyond where the bristles touch). We're convinced enough that in the sense of just letting the brush run as you gently work it around, all of these brushes can be effective cleaners despite their differences in "power."

While we rather imagine you know, you should be able to return your Essence+ to Sonicare for a refund.

I made some relative

I made some relative measurement between the hand pieces and brushes. An accelerometer was located mid brush-head behind the brush. These are no-load measurements (other than the mass of the accelerometer and mounting block) so they do not simulate brushing pressure. They also don't assess the different bristle designs.

Essence+ = 0 dB (set as baseline), fundamental frequency = 270 Hz (32,400 strokes / min)
Original handle with currently available brush head = +5 dB (1.9 times stronger), Fundamental = 260 Hz (31,200 strokes / min)
Original handle with original A-Series brush head = +7.3 dB (2.5 stronger than Essence+), Fundamental = 260 Hz (31,200 strokes / min)
HealthyWhite+ = +10 dB (3.2 times stronger than Essence+), Fundamental = 260 Hz (31,200 strokes / min)

Notes:
- A-series brush total length is shorter than current brushes.
- HealthyWhite only examined at full power
- Harmonic content not quantified but it appeared similar between configurations

My guess is the Essence+ that I had was defective and not necessarily designed to be that weak. The slight frequency shift might also be indicative of an issue.

If I was doing this "for real" the brush would have been modified (sanded flat, tri-axial accelerometers epoxy mounted) and a simulated brush force applied. Would be interesting to measure the signal transmitted through the bristles to a simulated tooth!

I've been using the HealthyWhite+ for about a week. The AdaptiveClean brush head feels significantly stronger than the SimplyClean brush, buts its big. With a manual toothbrush I like smaller brush heads but it doesn't seem to be a problem with it on the Sonicare. I have not yet tried the DiamondClean brush that came with the HealthyWhite+.

Thanks for taking the time to

Thanks for taking the time to experiment and post (Rob?).

It'd be appreciated if you could help with some clarification.

You compared:
Essence+
An old A-series brush handle with an A-series brush head.
An old A-series brush handle substituting an e-series brush head.
HealthlyWhite+

When running, the Essence+ vibrated at 270hz, all of the others at 260hz (the 31,000 strokes per minute that Sonicare usually states).

Beyond that, your decibels number is a measure of power ... and you found the HealthWhite+ to be the most powerful (stronger) of the lot? You also found that in the case of the A-series brush handle that it with the original A-series brush head made a more powerful combination than it with the e-Series (a smaller, lighter brush head).

You also make mention of a subjective comparison of the Adaptive Clean vs. Simply Clean brush heads when mounted on the HealthyWhite. What you have noticed seems to correlate with the grading scale that Sonicare assigns to their brush head lineup.

Thanks again for posting your information. Please point out my errors in interpreting what you have posted if needed.

You got it!

You got it!

I was measuring acceleration which is related to velocity, displacement, and power. When you turn up the volume on your stereo, the speaker cone vibrates at the same frequency but it moves a greater distance so its acceleration and speed also increase.

Thanks again Rob.

Thanks again Rob.

Diamond clean

Had a Essence for years....loved it. When it died I bought Diamond Clean. What a piece of crap. Does not charge well. I get one brushing between charges. Travel with it? No way. I would never ever under any circumstances recommend this product. I would give it 0 stars as a rating.

Thank you for this very informative website. I appreciate the info very much.

Wes,

Thank you for posting.

At times Sonicare customer service can be accommodating. You should call them with your complaint to see if they will offer you a replacement. Their stats say that that model should hold a charge for "up to 3 weeks." Let them know what's going on and see if they'll offer a solution.

7 1/2 years later: Philips Sonicare HX6932/10 FlexCare RS930

I've owned this Philips Sonicare HX6932/10 FlexCare RS930 for 7 1/2 years now. It has served me well. They don't make that particular model anymore. It still works great and holds a long charge (more than 10 days for sure). The only issue is that the "on" button is covered with a silicone type material that has started to peel off and deteriorate. That made turning it on and off difficult as the material is clogging the mechanism on the inside. I fixed it once but it got clogged again so I'm finally replacing the brush. Based on your thorough reviews (thank you so much for that) I just bought a HealthyWhite +. I hope that the quality will be as the old FlexCare. 7 1/2 years of service is great for a toothbrush, don't you think?

IK

Yes it was. We find it so sad that that doesn't seem more of a goal for electric toothbrush manufacturers (all of them) than just adding more gimmicks to each new model.

Big Box store model comparison

One main big box store carries three models (two each). The middle priced model is called Philips Sonicare ExpertResults 7000 Electric Toothbrush and the model number is HX7533/01. I can't find that number in your review. Can you help me out?

Ed B

We googled around and are under the impression that that brush has:
Built-in pressure sensor, 3 modes, 3 intensities, 2 x BrushSync features

Based on those features, to us it seems that model is most like the ProtectiveClean 6100. But using the information you have about the model, you should make your own comparison and draw your own conclusions. Some times the items sold in big box stores are special deals for them from the manufacturer and have some unsuspecting feature whittled off them, so they can be sold at a cheaper price, so check.

Big Box store model comparison

Thanks for your information. I did go out to the philips sonicare site and they have it listed. However, it says it is no longer available. Must have been a earlier years model. Thanks again.

Ed B

Yes and no. That page on their site doesn't make much sense. It may be a discontinued model but it's not an old model that's been discontinued. The ProtectiveClean line (that seems to have the same set of features as the one you're looking at) is the 2nd newest line they offer.

From a website visitor -

I had the same question, but was able to find the item listed on the Sonicare website.

Thanks very much for you detailed and informative website!

Choosing my first Sonicare

First of all thank you for the thorough comparison. I've been searching around looking for an optimum quality/cost balance to choose a brush, and so far the Healthy White + seems to be the one.
However, the stores in my country also have a Healthy White model HX 6711, that is cheaper, and the only difference I see is that it has only 2 modes, and no intensity settings. But I couldn't find it in your review. Is this some older model that was discontinued in the US? What can you tell about HX 6711?

SD

We're under the impression that the HX6711 is an old model (sold back around 2009 - 2012 or so). It was superseded in the Sonicare line up by the HealthyWhite+ maybe around 2015.

In it's heyday, the HealthyWhite was one of Sonicare's better lines (only the Flexcare as "higher"). The HX6711 was the lower end of that line of brushes ( 2 modes, and no intensity settings. The higher end HealthyWhite had a Sensitive mode in addition).

In terms of a reliable brush that has Sonicare's 31,000 brushing action, one would anticipate that that would be a good choice.

There might be some question whether that was a newly manufactured brush or one that had set in some warehouse for an extended period of time (battery issues?).

Great site - Aha series-3 and series-7 explained

My Sonicare series-3(HX6730) quit working so i went shopping for a new Sonicare. My head began to become overloaded on the various models displayed on the shelf. Models ranging from DiamondClean Smart, Platinum, Healthy White Felxcare, Sonicare-3, Sonicare-2. What in the world? Why did Sonicare make it so difficult to replace my broken Series 3 with one of these other models. I was happy with what I've been using for years. My dilemma. Do I need these upgrades? This site has taken all the mystery out of the Sonicre terminology. Thanks
