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.

• DiamondClean Smart
  
• DiamondClean
  
• ExpertClean
  
• FlexCare Platinum Connected
  
• FlexCare Platinum
  
• FlexCare+ (plus)
  
• HealthyWhite+ (plus)

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.

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.

• Utilizes click-on brush heads. (An important feature that allows you to select from the full range of click-on Sonicare brush heads.)
• Features Sonicare's hallmark 62,000 brush movements/minute brushing action.
  

  (Brush setting: Clean mode, High intensity.)

• Easy-Start, SmarTimer, BrushPacer.
• Glass charger. (Sonicare's spiffier recharging device.)
• Lithium-ion battery. Operates "up to 2 weeks" on a full charge.
• Sample promotional leaflet: DiamondClean Smart toothbrush.

 

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.

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.

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.

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.

Prices.

Model numbers associated with this product line: HX6921/04

Distinguishing features of the FlexCare+ line.

• 5 brushing modes (Clean | Gum Care | Refresh | Sensitive | Massage).
• (Note: This line does not feature brushing intensity settings.)
• (Note: No dedicated brushing pressure sensor.)
• No additional replacement brush heads included.

 

Additional FlexCare+ 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: 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.

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.
• 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: 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.

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.

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.

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

Distinguishing features of the ProtectiveClean line.

• 6500, 6100 - 3 brushing modes (Clean | Gum Care | White) and 3 brushing intensities (High, Medium, Low).
  

  5100 - 3 brushing modes (Clean | Gum Care | White).

  4100 - 1 brushing mode (Clean).

• 6500, 6100 - BrushSync brushing mode pairing. Smart sensor technology: Pressure sensor, brush head replacement.
  

  5100, 4100 - Smart sensor technology: Pressure sensor, brush head replacement.

• 6500 - Travel case can be used as a charging station. (The case requires a USB connection for charging operations.)
  

  6100, 5100 - Non-charging travel case.

  4100 - No travel case.

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

 

Additional ProtectiveClean features.

• Utilizes click-on brush heads.
• 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.

j) The Sonicare for Kids electric toothbrushes -

Prices.

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

Distinguishing features of the For Kids line.

• Integration with Sonicare's For Kids smartphone app. (This app evidently doesn't have mouth-map or touchup reporting. But it does track brushing sessions, their duration, and gives brushing tips and provides games that can help to increase brushing motivation.
• 2 brushing modes (High, Low). (The lower setting is intended for use by smaller, younger children.)
• Comes with an assortment of interchangeable stickers that can be applied to the brush for decoration.
• Some models come with an additional replacement brush head.
• (Note: No dedicated brushing pressure sensor.)
• No travel case.

 

Additional For Kids features.

• Utilizes click-on brush heads. - The brush heads (Standard and Compact sizes) that are intended for use with the For Kids line are generally smaller in size and softer-bristled than those designed for adults.
• Features Sonicare's hallmark 62,000 brush movements/minute brushing action.
  

  (Brush setting: High mode.)

• Easy-Start, KidTimer, QuadPacer.
• Traditional charging base. Lithium-ion battery. Operates "up to 3 weeks" on a full charge.
• Sample promotional leaflet: Sonicare For Kids toothbrush.

 

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.

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.

• 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.

d) 110 - 220V charging.

e) Smartimer / KidTimer.

(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.

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.

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.
