Oral-b features explained on this page.


The Bluetooth connectivity / Smartphone app.

What does having Bluetooth connectivity do?

The Oral-B Bluetooth option allows your toothbrush to communicate with an app installed on your smartphone (iPhone or Android) to give you real-time feedback about your current brushing session and past history. The app is free and can be downloaded from the usual places (iTunes, Google Play).

Oral-B would suggest that the phone app helps to motivate your brushing habits, as well as improve your session's effectiveness and safety.

What type of details does the app report?

The information shown on your phone includes:  a) The brushing timer.   b) Quadrant indicator and timer.   c) Toothbrush mode setting.   d) Excessive pressure warning.   e) Brush position detection.

Note: A lot of this information is a duplication (albeit in a nicer visual form) of what your toothbrush already indicates to you via sound, light or vibration.

Special phone app features - Varies according to model.

  • With brushes that are enabled with the Artificial Intelligence feature, motion sensors recognize your brushing style, track where you have brushed (visible on the app) and give you real-time feedback to improve your results.

    This is Oral-B's current state-of-the-art brushing/mouth-mapping feature. It's easier to use than the previous Position Detection feature.

  • Oral-B's Position Detection feature uses facial recognition technology to guide your brushing session, zone by zone (UL, UR, LL, LR, UF, LF), thus helping you maximize your brushing effectiveness. This seems to be the older, previous-generation version of Oral-B's brushing/mouth-mapping feature.
  • Pre-programmed routines can be used that are designed to help you attain your brushing goals (Fresh Breath, Plaque Fighter, Whitening, Gum Health and Ortho Care).
  • The app can customize your toothbrush's brushing timer by configuring additional seconds for those areas of your mouth (quadrants) that require extra cleaning.
  • The app displays your brushing history (number of sessions, session duration, assorted other statistics) over time. Up to 6 months of data can be stored. Sessions less than 30 seconds aren't included in the tally.
  • The app can be configured to remind you to floss and brush your tongue after each brushing session. It can also remind you when it's time to replace your brush head.
  • To help with entertainment and productivity while you brush, it displays news headlines, your calendar and weather information.


Is the Bluetooth/Smartphone app a valuable feature to have?

a) Pros.

  • For people who rely on a brushing timer, the fact that you can use the app to extend its duration and customize when its quadrant timer signals is a nice, possibly important, feature.

    (Just so you know however, once an Oral-B's brushing timer has signaled completion the toothbrush doesn't automatically turn off. So you can, even without customization, just continue to brush for longer if you want. It just won't be a timed event.)

  • For lackadaisical brushers, models configured with Position Detection can identify for them areas where they have missed during their current brushing session.

    Also, being able to review their brushing history or use one of the pre-programmed routines might serve as motivation to brush more regularly or for longer.

  • If your kids are problem brushers, the app might provide a way of helping to keep track of what their habits actually are. Also, as a means of motivation the app lets the user win "trophies," like having performed 7 consecutive days of brushing.

    Advantage: Your child will have to brush for at least 30 seconds for their session to even be recorded.
    Disadvantage: Just because the app detects the brush running doesn't necessarily mean that it's in their mouth.


b) Cons.

  • As mentioned above, besides the customized timer and brushing history features, the app reports little to you that your toothbrush doesn't already indicate to you on its own.
  • Before you make this option the sole feature that you've based your purchase decision on, you should read the reviews for the Oral-B app on the iTunes and Google Play websites.

    Doing so can give you an idea of the kinds of problems that other people have with using it (the reviews aren't universally positive). User satisfaction possibly varies with the platform (Android vs iPhone).

  • The news, calendar, weather and entertainment feature is as unimpressive as you might expect. By creating it Oral-B has found a way to help you burn through your monthly data allowance, just by using your toothbrush.

    (2-minute brushing sessions X 3 times a day X 30 days a month = 3 hours of additional connectivity.)


Is it important to buy a model that has this feature?

If having the ability to customize the duration of the quadrant brushing timer, keeping track of brushing sessions over time or the "trophy" motivational feature are useful items in your application, then yes.

Otherwise, we don't see why this would be considered to be a vital option. If you just need a longer brushing duration, why not use the timer that's already on your phone. You don't need an app for that.

Tip:  If you think the smartphone app is important to have and use, you can find it on Pro 5000 and above.

The wireless SmartGuide unit.

The Oral-B SmartGuide is a stand-alone unit that communicates wirelessly with your toothbrush. It's not a control or a touch screen, it simply reports information to you via an LCD display.

Fewer and fewer models now come with this feature. For all practical purposes, it's been replaced by the functionality of the Bluetooth connectivity/Smartphone app feature discussed above.

Smartguide features.
  • When the toothbrush is in use, the unit displays:

    a) The brushing timer.   b) The quadrant indicator (the dashed circle on the unit's screen).   c) An excessive brushing pressure indicator.   d) The brushing mode in use.

  • When the toothbrush is not in use the unit serves as a clock and shows the time of day.

Additional details.
  • The brushing timer can be set to count either up or down.

    After counting down, the timer will automatically reverse and start counting back up. That way if you decide to brush for longer, you can keep track of how long.

  • The unit displays a circular quadrant indicator. This helps you to keep track of which 1/4th of your mouth you should be brushing at the moment.
  • The Smartguide is not rechargeable like your toothbrush. It runs on 2 disposable AAA batteries. Oral-B states that they should keep the unit running for about 1 year.

Is the Smartguide an important feature to have?

It's easy enough to dismiss a true "need" for having the SmartGuide unit. That's because so much of the information it relays is already signaled to you by your toothbrush via various sounds, lights or vibrations.

Having said that, some users may find that having this information relayed to them visually is beneficial.

  • We do see how being able to track how long you've brushed for after the 2-minute timer has lapsed could be useful.
  • And if someone who brushes via quadrants actually has trouble keeping track of which one they should be on, the "quadrant circle" would be a help too.
  • As a point of interest, Oral-B actually did a study to determine how the use of a remote timer (the SmartGuide) affected users' brushing habits.

    They determined that using one encouraged users to brush for at least 2 minutes and to maintain a stricter brushing regimen.

    We will point out however that the study period only ran for 30 days. A time frame during which we'd expect that the novelty of using the Smartguide hadn't worn off yet.

Using a "connected" Oral-b toothbrush on airplanes.

As described above, some Oral-b models have Bluetooth/wireless capability so a connection can be made with other devices (smartphone/Smartguide unit).
Airlines have varying restrictions on the use of wireless devices on flights. Some of them ban their use, others place restrictions on the type of device that's permitted and/or when such units can be used.
  • When your toothbrush is switched off it emits no wireless signal, so it poses no conflict with existing rules.
  • When your toothbrush is turned on, its wireless transmitter turns on too. And for this reason, the use of your brush during your flight may or may not be permitted, depending on your airline's rules.
  • Check the user manual of your brush to determine if the wireless transmissions generated by your model can be deactivated. If so it can then be used (such as on your flight) without the emission of signals.

    (With some Oral-b models you hold the on/off and mode button down for 3 seconds until
    the radio transmission display/icon on the brush body goes off. Repeat the process to turn the signals back on.)

The Oral-b 360 Smartring.

The Smartring is a flashing indicator light. The "360" portion of its name refers to the fact that the Smartring encircles the brush handle (it's found right below where the brush head attaches), and therefore can be visualized from all angles.

The Smartring is used to signal the following functions:

  • Excessive brushing pressure has been detected (red light).
  • That another 1/4th of your brushing timer's setting has elapsed. Also that the brushing timer's total duration has ended. (The default color of this feature is white, although other colors can be chosen via the smartphone brushing app.)
  • That your toothbrush has paired (via a Bluetooth connection) with your toothbrush (blue light).

The default color of the Smartring can be personalized to any one of 12 different options. Choosing to do so is just decorative in nature.

Oral-B brushing and quadrant timers.

All of the toothbrushes making up our all-models list come with a brushing timer.

  • For the most part, this is a 2-minute one. (When a brush is set to Deep Clean brushing mode, the timer extends to 3 minutes. Only selected models feature this mode.)
  • As the timer runs, its quadrant feature signals 30-second intervals (45 seconds when set on Deep Clean.) (The Vitality models don't offer a quadrant timer.) See below for how this is used during brushing.

    The signal that's used varies by model but is typically a pause-and-stutter coming from the toothbrush handle. For models equipped with the Smartring feature, it's light flashes at both quadrant and end of timer intervals.

  • Unlike some other brands of toothbrushes, once an Oral-B's brushing timer has lapsed the brush continues to run (it doesn't automatically shut off). That means you can seamlessly continue brushing for longer if you want. This is a nice feature.

How to use the quadrant timer.

  • Imagine your teeth in terms of quadrants (e.g. upper right, lower right, lower left, upper left).
  • As you brush, when each 30-second quadrant signal sounds off, you advance to the next quadrant in your brushing plan, brushing it until the timer signals you to advance again.
  • There's nothing really special about brushing this way. It just helps to ensure that you don't overlook brushing any one area for an adequate amount of time.
Customizing the quadrant timer with the Bluetooth/Smartphone app.

The brushing/quadrant timer of toothbrush models that feature the Bluetooth/Smartphone app can be extended (see above).

The Oral-B pressure control feature.

Most mid and higher-end Oral-B electric toothbrushes feature an excessive brushing pressure indicator.

While the specific design of this feature varies by model, in general when your brush detects that excessive pressure is being used:

  • It signals via a light, sound and/or makes a change in your brush's brushing action that you'll feel or hear.
  • Toothbrushes equipped with the Smartguide or Bluetooth/Smartphone app features also show a signal on their screens.
Feature benefits.

Brushing with excessive pressure can cause tooth wear, gum tissue abrasions and theoretically even gum recession. It will also tend to wear out brush heads prematurely.

In regard to gum recession, studies have shown that the use of either Sonicare (McCracken 2009) or Oral-b (Rosema 2014) powered brushes do not place the user at risk of damage [page references]. And for that reason, we don't favor one brand over the other, despite the fact that Sonicare products do not offer this same type of warning system.

As a best practice, when you brush with an electric toothbrush just hold it in contact with your teeth and let it do all of the work. There's no need to press hard or scrub.

Oral-b recharging stands.

  • All models come with a basic circular charging unit that plugs into an electrical outlet (the brush sits directly on top of this device). It's small enough that it packs easily for travel.
  • More expensive Oral-b's come with a plastic tray designed to fit around the basic unit so to hold additional brush heads.
  • Some high-end models come with a combined travel case/charging unit. The case can also be used to simultaneously charge your cell phone.

Recharging your Oral-B.

How it works.

Oral-B rechargeable toothbrushes charge by way of induction. This means you simply set them on their charging stand, no direct connection is made (like plugging in a wire).

Battery level indicators.

All Oral-B's feature a battery charge indicator, although its design (level of sophistication) varies by model.

  • Some simply indicate that the unit has enough charge to perform (or not).
  • Others give you an idea of the actual level of charge the brush still holds. This may be an important feature for people who want to travel without taking their charger along.
Best practices.

Oral-B states that you can help to ensure that your toothbrush's battery will maintain maximum recharging capacity by using it straight through (multiple sessions, no charging in between) until it's fully discharged. They suggest doing this at least once every six months.

Note: Many models are 120 volts only.

It bears mentioning that the charging unit that comes with mid-range to low-end Oral-B toothbrushes is typically one that's just been designed to be used with the type of electrical system that predominates in the country/area in which it was originally sold.

That means that USA/Canada models are intended for use only with 110-120 volt systems. Units bought in other countries (such as those in Europe) are typically designed just for 220 - 240-volt systems. (In comparison, most Sonicare products feature multi-voltage charging units.)

Multi-voltage chargers.

Some high-end Oral-B models come with a multi-voltage (110-240 volt) charging unit. In most cases, the needed transformer has been integrated into a power cord that has come packaged with the brush. The cord is then plugged into either the toothbrush's standard charging base or else its charging-capable travel case, depending on which you intend to use.

How to check.

The specific voltage system your toothbrush charger has been designed to work with should be printed on its base. Those specifically marked "100 - 240 volts" can be used globally without the need for a voltage converter. All others will require a converter to operate on any electrical system other than the one they were designed for.

Battery types / Replacement.

a) Oral-b rechargeable batteries.

Higher-end Oral-B models typically feature a lithium-ion battery. Lower-end brushes typically have a NiMH one. The lithium-ion version offers the advantage of longer, more consistent battery life and faster charging.

b) Oral-b's aren't designed for battery replacement.

The design chosen by Oral-B for their rechargeable toothbrushes is one where the batteries housed inside aren't intended to be replaced by the consumer (at least not in a simple, straightforward way). That means battery failure generally correlates with unit death.

(Note: Oral-B does sell "battery operated" toothbrushes, meaning models that run on replaceable off-the-shelf disposable batteries. Our website doesn't recommend the use of these types of units because the brushing action they create is subpar compared to that of Oral-B's rechargeables.)

Battery replacement options.

We have run across some websites and eBay stores that appear to offer replacement rechargeable batteries for various Oral-B models. While we have no first-hand experience in dealing with them, what they offer seems to fall into one of the following two categories.

  • Some sites appear to just sell the replacement batteries themselves, implying that you the consumer perform the repair task on your own.

    Typically the website will provide instructions. We've also run across some YouTube.com videos that demonstrate how to perform this procedure. At a minimum, you'll need to be proficient with using a soldering iron to make the switch.

  • Other companies state they offer battery replacement as a service. You ship your inoperable toothbrush to them. They make the repair, check the outcome and then return it to you.
It seems to us that if the route of battery replacement is chosen, afterward it's unlikely that your brush will retain its original level of resistance to moisture (factory seals have been broken). Taking extra precautions in that regard should help to extend the lifespan of your repair.

Tip:  The higher-end Oral-b's offer more of the features discussed on this page. Further on down the lineup are their more value-oriented models, although it's difficult to suggest purchasing any one below the Pro 3000.



Rechargeable Batteries Don't Last Long

I went from a standard battery powered Oral B to a rechargeable model last year, but discovered the rechargeable battery only lasted about 15 months. It then died and would no longer take a charge. When I investigated replacing the rechargeable battery, I learned that the device is not designed for it to be replaceable. In other words you have to take the whole thing apart, modify a store-bought rechargeable battery to fit and then solder it back in before reassembling. Poor design unless you want to design obsolescance. A complaint to the company didn't go anywhere, not even an acknowledgment that the design should be changed to make the battery replaceable!

* Comment notes.


We agree with your complaint and consider a design of planned obsolescence an insult to both consumer pocketbooks and the environment. However, we can't say that this approach is unique to just Oral-B. Sonicare products get a "fail" in this regard too.

You seem well versed on what your options are. But for others, we discuss Oral-B battery replacement here.

Planned-obsolescence design is just another reason to follow this page's suggestion. Buy the cheapest model that meets your needs and nothing more.

Battery recharge life

I have owned 2 lower cost Oral B brushes over the last 2 or 3 years. Previously my more expensive model lasted for a few years before not taking any recharge. I don't have the receipt so not sure how long the cheaper ones lasted but I think it is about a year. I wondered if it is a cheaper battery but you say they are cadmium (NiCd) rather than the top end ones being Lithium. My latest one stopped after recharging in Bali. Is the voltage difference a possible cause? I would have charged the previous one over there as well. Or is it more likely a cheaper quality battery? As the action is inferior I will try the one you recommend but need to find out about Bali voltage and will keep my receipt incase it stops after one year.

* Comment notes.


There should be an indication on your brush's charger as to what voltage(s) it has been designed for.

We're under the impression that the Pro 6000 is the cheapest Oral-b that has a lithum-ion battery.

Oral B that doesn't shut off when pressure is to hard

Can you recommend the best Oral B that doesn't shut off when pressure is to hard? I don't care for this function but want 40,000 and don't need blue tooth.

* Comment notes.


The 3000 and all of the models above it are designed to slow down (reduce motor speed) when too much pressure is detected but not stop. And all of these models feature Oral-b's 3D, 40,000 pulses per min brushing action.

Oral B model 6000

what type battery is used. How can I change the battery? Does it need soldering like the old model 5000 that I know have and cannot get a battery since it was disc.

* Comment notes.


We don't have any information to share. The 6000 features a lithium ion battery, and we can tell you in general terms why you would want a brush that does.

But replacement equivalents or battery replacement guides aren't the type of information we cover. Youtube and eBay are great sources for that type of information.

Good luck.

Multiple user data via app

Do you know if the app can track multiple users' data? Or alternatively, do you know if the brush can pair with more than one smartphones? This is as I'm planning to share the handle with my better half. TIA

* Comment notes.


We're under the impression that if user #1 has the brushing app open on their phone, that brushing session will be documented on their phone.
Then, the next time the brush is used (brusher #2), if user #2 has the brushing app open on their phone, their session will be documented on their phone.

A problem arises when the brush is used without anyone's phone app being open. In that case the session is stored by the handle. That stored session is then sent to the first phone that the brush later on syncs with, no matter which user's phone that is.

Flashing green light on rechargeable oral b toothbrush

Why is it flashing for long periods?

* Comment notes.


The flashing green light (at least the one we're familiar with) indicates that the brush is charging. Depending on the initial conditions, it can take a brush up to about a day (24 hours) to fully charge.

Oral b charger

green light shows, charger warm to touch, brush head does not rotate and sound weak....is it "finished" or is "fix" possible

* Comment notes.


We'd anticipate that it is a battery issue but don't know.

If that's the problem, there is no official Oral-b fix but there are some companies (eBay) that offer battery replacement. However, once that repair has been completed a brush is no longer as water tight as it was before.

If you've had this brush a while, it might be time to punt.
