The 5 best smart toothbrush choices in UK

The 5 best smart toothbrush choices in UK 1

The word ‘smart’ is being used more frequently in the product names and marketing materials for many of the latest toothbrushes.  

But, what does ‘smart’ really mean?

Typically, any toothbrush product labelled or marketed as smart has features built-into it that offer a more intelligent and enhanced user experience.

There are different levels of smart features, as explained in our buyer’s guide. Irrespective, the ultimate aim is to improve your oral health standards and routine.

The most common is the inclusion of Bluetooth technology that allows the toothbrush handle to connect to a smartphone application.  Data is shared between them to offer enhanced functionality, compared to a regular manual or electric toothbrushes.

Whilst it is not limited to the addition of Bluetooth, this is the trend to date.

  • A plastic manual toothbrush is not smart.
  • A rechargeable electric toothbrush with a couple of cleaning modes is not typically considered smart.
  • A rechargeable electric toothbrush with a couple of cleaning modes, Bluetooth connectivity, and a smartphone application that shows you precisely where the toothbrush is in the mouth, is a smart toothbrush.

Just before I give my recommendations for the ‘best’ smart electric toothbrush, let me be quite direct and to the point for a moment.

  • You do not need a smart toothbrush.
  • A smart toothbrush on its own will not clean your teeth any better.
  • A smart toothbrush still relies on you to really take advantage of the benefits it brings.

Not all smart toothbrushes are made equal.  There are a lot of small and subtle differences between them that are not always obvious until you use them. Some are just not as smart as you might think.

Which smart toothbrush should I pick?

If you want a smart toothbrush, I urge you to pick the one that fits your needs and wants best.

I offer my recommendations, with reasons as to why, but the comprehensive buyers guide included will offer further insight into the different types of smart toothbrushes and will guide you to select the brush that is right for you.

The article is broken up into two sections:

Our top 5 picks for the best smart toothbrush

In the sections below you can read a bit more about why we have included each smart toothbrush on the list.

1. Sonicare DiamondClean Smart

Level 0 – Device control and customisationLevel 1 – Brushing time and pacingLevel 2 – Data and habit trackingLevel 3 – Real-time habit tracking

If you want the absolute best, and money is no object then the DiamondClean Smart is the brush to go for.

As a complete package it is the best.

It is a premium toothbrush with all of the best technology built-in.

Not only does it look the part, it feels the part and you get lots of extras in the box.

Of notable mention is the travel case that holds the handle and up to 2 brush heads.  However, you can also charge the toothbrush whilst it is inside, by connecting the USB cable that is hardwired into the case, into a USB power supply.

You don’t need all of the features it offers, but if you are committed to your oral health then you will likely find some real value in this.

2. Oral-B iO

Level 0 – Device control and customisationLevel 1 – Brushing time and pacingLevel 2 – Data and habit trackingLevel 3 – Real-time habit tracking

The iO is the best looking and performing Oral-B toothbrush I have ever used. 

The revised design of the iO is not only visually appealing, but it means that the cleaning action has been enhanced and the noise that it makes reduced too.

Adding a display into the handle looks and feels premium, but it doesn’t really offer a great deal more than those without.

And as you would expect, it cleans the teeth really well, considering it is from a brand leader and is a top of the line brush.  

A lovely toothbrush it is, the overall package is not quite as complete at Sonicare for the price asked of it.

It is technically the best product Oral-B offers, but better value options exist.

3. Oral-B Genius X

Level 0 – Device control and customisationLevel 1 – Brushing time and pacingLevel 2 – Data and habit trackingLevel 3 – Real-time habit tracking

An excellent toothbrush that cleans the teeth really well, whilst offering some nice smart features and functions.

It demonstrates how technology can help you achieve the best oral health care standards.  

It is not perfect though. The graphics in the smartphone application could be improved to enhance the way that it educates you about the areas of the teeth you have and have not brushed. 

The Genius X lacks the finer details and quality that comes with the likes of the Philips Sonicare DiamondClean Smart.

4. Oclean X

Level 0 – Device control and customisationLevel 1 – Brushing time and pacingLevel 2 – Data and habit trackingLevel 3 – Real-time habit tracking

The Oclean X cleans the teeth well and looks lovely.

It charges quickly, has a long battery life and the magnetic mount is brilliant.

Although it tracks the position of the brush in the mouth, the data from that tracking is not presented until after the brushing session is over.  But, positively the accuracy of the tracking is better than I anticipated.

The Oclean X had a small colour display, before it was introduced in the iO, but sadly, it is frustrating to use.

Given what it offers for the price, it is impressive.

5. Sonicare EpxertClean 7300

Level 0 – Device control and customisationLevel 1 – Brushing time and pacingLevel 2 – Data and habit trackingLevel 3 – Real-time habit tracking

An excellent electric toothbrush with smart features, but no real-time tracking.

More cost effective as a result of not having this tracking, it is debatable whether the savings are worth it when the likes of the DiamondClean Smart and Genius X are arguably more rounded products.

But, the brush head replacement reminder system and the in-case charging are a couple of the appealing features.


  • Design and materials
  • Multiple cleaning modes
  • Built-in timer and pacer

Smart Electric Tootbrush Buyers Guide

All you need to know about smart toothbrushes and deciding which is right for you.

What do smart toothbrushes offer?

The answer to this question ultimately differs depending on the specific toothbrush you are referring to.  Technology is constantly evolving and the capabilities increasing.

The principle behind any smart toothbrush is to improve your toothbrushing and your user experience in some way so that in the long term you have better oral health.

Manufacturers recognise that some of us require more encouragement and support than others.  Their products use innovative technology to motivate and help us to achieve the best clean and oral care standards that we can at home.

Nobody will brush perfectly or for the recommended amount of time, all of the time.  Even the most thorough of toothbrushes will at times miss parts of the mouth or use the wrong technique or not brush for as long as they should.

The smart toothbrush is designed to tactfully get us achieving better standards than the vast majority.

Up to 50% of the world’s adult population have gum disease according to the World Dental Foundation.  Gum disease is an entirely preventable condition.

Poor brushing habits and techniques are partly to blame for this.  Technology in these smart toothbrushes is working to help reduce this alarming statistic.

Those that do this job the best will win more customers and arguably profit in the long term as a result, so smart technology can benefit you and the manufacturer.

How do smart toothbrushes work?

Over and above the core electronics (battery, motor, circuit board etc) needed for an electric toothbrush to function, smart toothbrushes will have a number of pieces of additional technology built into them.

The most basic piece of technology is a Bluetooth chip that allows the handle to communicate with another Bluetooth enabled device, wirelessly.  This other device is normally a smartphone or tablet computer.  

More premium and capable models will have additional components like a g-sensor/accelerometer as well as other sensors to detect the position of the brush.

Depending on precisely what technology is being built-in there may too be additional pieces of hardware and software included.

The toothbrush manufacturer will normally offer a free application for both Android and iOS devices that can be downloaded to your smartphone or tablet.

Quite often there are minimum hardware requirements for this.  Assuming your mobile device meets these requirements, the application becomes the interface for obtaining the data that the toothbrush handle collates.

Raw data is sent from the toothbrush handle to the application, once the 2 devices are paired and within range of each other.  The app takes the data and presents it in a way that is more informative and engaging, allowing you and me to really see and understand our brushing habits.

Understanding just how well or not we do brush allows us to make improvements, that should, in theory at least, allow us to take better care of our teeth and gums.

More of these apps now compare the data with other data sets they hold and your own previous brushing data to give more useful feedback and constructive tips on how to further improve.

In the long term, this education will help you have a better oral healthcare regime.

Whilst it depends on the brand and application, there are also other features to the apps. For example, many make it easy to purchase replacement brush heads and offer personalised brushing journeys to help achieve your own goals.

You can even update the software of the toothbrush handle to add new features and improve performance.

Of course, there is at least 1 product that breaks the mould, in this instance, it is the Oral-B Sense and the Oral-B Guide.

The difference with Sense and Guide is that the handle connects and communicates via Bluetooth with the charging stand.  This charging stand has WiFi built-in.  The data is then sent to the cloud.  A smartphone application then pulls the data from the cloud, rather than taking the data directly from the toothbrush handle.

How do smart toothbrushes differ?

As I have already suggested, smart toothbrushes can potentially differ in quite a few ways.

But, to some extent, the technology and the purpose can be categorised or organised into different levels.

At the time of writing, the majority of the smart toothbrushes fall into the following groups:

  • Level 0 – Device control and customisation
  • Level 1 – Brushing time and pacing
  • Level 2 – Data and habit tracking
  • Level 3 – Real-time habit tracking

In most instances, the levels are building upon the level beneath.  So, those categorised as level 3 have the core features of level 1 and 2.

Let me explain each of these levels in a little more detail.

Level 0 – Device control and customisation

The most basic of interaction and control between the toothbrush and smartphone application.

This will allow for specific features and functions of the toothbrush to be enabled or disabled and settings customised.

Examples include changing the brushing duration, the speed/intensity of the clean or the order of the different cleaning modes on the toothbrush.

Level 1 – Brushing time and pacing

The most basic of smart toothbrush features, but one of the most vital.

Here, the focus is on getting you and me as a user of the toothbrush to brush for the dentist recommended amount of time, typically 2 minutes.

Far too many don’t brush for anywhere near the right amount of time, so a smart toothbrush can help encourage us to do so by offering on-screen notifications, warnings, and other visuals to how long we have been brushing for and how long we have left to go.

This is normally working in real-time, so as soon as the toothbrush is turned on, an on-screen timer will begin the countdown.

Quite often, the timer shown on screen in a circle. That will fill up/change colour the longer that you brush for.  The aim is of course to complete the full 2 minutes.

The 5 best smart toothbrush choices in UK 5

However, it is all very well brushing for 2 minutes, but focusing all that time on just the front teeth is no good.  So, the brush and visual on-screen will encourage you to change areas of the mouth as you brush.

Typically, the mouth is broken up into 4 sections (quadrants).  These are upper right, upper left, lower right, lower left.   

The idea is that you spend 30 seconds cleaning all the tooth surfaces in that quadrant before moving to the next.

So, after 2 minutes, you will have successfully brushed all the tooth surfaces in the mouth, having spent 30 seconds on each.

This pacing of the clean can also be broken down into 6 sections, each of 2 seconds in length, but the principle is the same.

The most basic brushes will not retain this data after the clean has been complete.

Level 2 – Data and habit tracking

The vast majority of smart toothbrushes fall within this category of data and habit tracking.

At the core, they will have the timer and pacing functionality, as per a level 1 smart toothbrush.

But, unlike a level 1 smart toothbrush, the data will be retained after the brushing session.

This data will then be logged within the app, for review post brushing or in the future.

How long the data is retained for does vary.  Some will retain it for a week or a month, but the best products in this class will retain it indefinitely.

The logging of the data allows you to review your performance and habits.

Therefore you can look back and see whether you have improved from perhaps brushing once a day for 60 seconds, to brushing twice a day for 2 minutes each time.

The logic is you can easily see your good and bad days when it comes to looking after your teeth and gums.

Some brushes within this category will simply log a brushing session was completed, whilst the better products will log precisely when (time of session) along with how long that session lasted.

Some, but not all will also offer the ability (potentially automatically) to retain other data such as whether you flossed or rinsed with mouthwash.

It is possible too, that the app will log if too much pressure was used when brushing the teeth too.

The 5 best smart toothbrush choices in UK 6

Select toothbrushes will also track the precise position of the toothbrush in the mouth as you brush.  So, you can see what areas of the mouth you might not have cleaned so well.  However, unlike level 3 brushes, the data is not shared in real-time only for review, post brushing.  

Ultimately the idea here is to build up a bit of a progress report for you personally, that you might then share with your dental professional to look for ways to further improve your oral care routine.

Level 3 – Real-time habit tracking

Arguably the best smart toothbrushes, these products deliver the ultimate experience.

What really sets these brushes apart is that provided the app is used at the same time as the toothbrush, you are given real-time feedback on your brushing.  Therefore you can adapt as you brush.

Those without the real-time tracking are educating you post brushing, so you know for next time.  Here you can make the improvements quicker and in theory, improve your oral health quicker too.

It is a little like having a dental professional by your side as you brush.

The hardware and software are constantly monitoring and will alert you when you need to make an alteration.

An example might be that you brush with too much force, so the toothbrush and app will alert you to this, so you reduce the pressure and reduce the damage.

You also may not be holding the toothbrush at the correct angle to get the best clean, the app can potentially alert you to this also.

It is possible you forget to brush a certain area of the mouth, on screen visuals will make it clear that this area requires brushing before you end your brushing session.

The 5 best smart toothbrush choices in UK 7

At the end of the brushing session you get a summary and feedback of your clean, with more actionable data.  

Often you are scored out of 100 for the level of coverage you gave to the teeth and a graphic makes it very clear what teeth were and were not brushed correctly.  

This, along with more standard brushing time data is retained within the app for review at a later date.

In theory you could look back to your bruising habits 6 months ago and see that you brushed for 60 seconds and achieved a 45% coverage, but now you are bruising for 2 minutes with an average 97% coverage.

Such products offer the potential for greatest oral care routine improvement.


It should be noted that whilst the preference will be for the toothbrush handle to sync with the smartphone app during or immediately after a brushing session, many brushes can retain data.  Therefore meaning you don’t have to have the toothbrush and smartphone together every time the brush is used.

Chips within the handle typically retain data for up to 20 brushing sessions, although this does vary by model.

This means that the data will be sent to the smartphone app the next time the toothbrush and smartphone are within range of each other.

To retain as much data as possible this connection should be made, before the maximum number of brushing sessions are reached.

It is too possible that in some cases less data will be retained if it is not shared in real-time.  For example, the time and date of the brushing session along with the duration may be stored, but not the real-time coverage information.

Which smart toothbrushes have which features?

As you will have learned by now.  Not all smart toothbrushes are made equal.

Just because a toothbrush is expensive, does not make it the best smart toothbrush and just because it has real-time tracking does not mean it should be the toothbrush you pick if you don’t care for that feature.

The following list contains the current smart toothbrushes available on the market.  

I have categorised them by the different levels/smart features that they offer.  Where applicable, I have made particular comments on things you should be aware of.

Level 0 – Device control and customisation

  • Amabrush

Level 1 – Brushing time and pacing

  • None at this time – Brushes like the Oral-B Stages Power for kids have associated apps but there is actually no Bluetooth connection. 

Level 2 – Data and habit tracking

  • Sonicare for Kids connected
  • Sonicare DiamondClean 9000
    • Data retained for a short period of time only
  • Sonicare ExpertClean (7300 & 7500)
    • Data retained for a short period of time only
  • Oral-B Junior Smart
  • Oral-B Teen
  • Oral-B Smart 4 4000
  • Oral-B Smart 5 5000
  • Oral-B Smart 6 6000
  • Oral-B Smart Series 6000/6500
  • Oclean X/X Pro
  • Xiaomi Mi

Level 3 – Real-time habit tracking

  • Sonicare DiamondClean Smart (9300, 9500, 9700 & 9750)
  • Sonicare FlexCare Platinum Connected
  • Oral-B iO (Series 7, 8 & 9)
  • Oral-B Genius X
  • Oral-B Genius 10,000
    • Requires front facing camera of the smartphone to perform real-time tracking
  • Oral-B Genius 9000
    • Requires front facing camera of the smartphone to perform real-time tracking
  • Kolibree Ara
  • Colgate Connect E1

How well do they work?

On the whole these products are pretty good in terms of what they offer.

Those brushes in level 1 and 2 are the most reliable and accurate because they are tracking the more simple data.

Those brushes that fall into the real-time tracking of level 3 are arguably the least perfect and reliable.  They are not perfect, nor will they likely ever be, however they are pretty good and perform well enough to be able to detect and alert to the most significant toothbrushing faults a user may have.

Most of the products I have tested offer a comparable experience.  Yes, one might be marginally better than another.  But, consideration must be given for the fact that technology and software is improving all the time, and because these products can also be updated over time, the performance can in fact get better, or in rare instances get worse. 

Such products have existed since approximately 2014 when Oral-B introduced the first smart toothbrush.  Other brands have since followed and despite launching products after Oral-B, the likes of Sonicare and Colgate offer extremely comparable products.

For the most accurate insight into how well they work, refer to our reviews of that specific smart toothbrush, as we will make comments on the performance at the time of review.

Smart toothbrush applications

Each toothbrush brand has their own smartphone application for their products.

Typically this app is made available on both Apple’s iOS platform and Google’s Android platform via the application store/marketplace found on each device.

More often than not these are free applications that can be downloaded by anyone.

Most companies have one app that is configured to work with all of that brand’s smart toothbrushes.

However, there are instances where a specific product or product range may have it’s own app.

Both Philips Sonicare and Braun’s Oral-B for example have different applications for their children’s smart toothbrushes, compared to their adult range.

Oral-B too has a different app for those products that have their ‘Oral-B Sense’ technology built-in.

The applications are updated more frequently than the toothbrushes themselves.  Therefore I will not comment on each brand’s smartphone application in any detail or make comments on which is best.  This is because what is the best today, might not be tomorrow due to updates.

Since this website began I have seen many iterations of the smartphone apps.  In most instances they have gotten better.

However, at times useful features have been removed or workflows changed.

On the whole the apps are very similar in what they offer, the design and menu systems can change.

It is an impossible task to make an app that all will be happy with.  We all have different needs and wants.  Too many features and controls can make the experience quite awkward and confusing, whilst too few controls can make what should be a smart product feel quite dumb.

There is scope for improvement in all apps I have seen and handled to date.

Our reviews of smart toothbrushes will make comments on the app version that is available at the time of review, but do bear in mind the app can be updated.

Why would I want a smart toothbrush?

This is a very common question and a valid one.

The primary reason for such is that technology allows for a new, exciting, engaging, and smarter way for users like you and I to get more information on how we brush and ultimately improve our oral health.

The main justifications or reasons for wanting a smart toothbrush are as follows:

  • I want to record/know when/how often I brushed my teeth
  • I want to record/know how long I brushed my teeth for
  • I want to learn how I can brush my teeth and improve my oral health
  • I want to be shown which parts of the teeth I am not brushing or missing
  • I want to be scored/rated for my brushing experience
  • I want to be motivated to brush to a higher standard
  • I want to be able to show my dental professional how well I am brushing
  • I like technology and want the most capable toothbrush

I don’t want a smart toothbrush

If you do not want a smart toothbrush, this is quite ok.  As I suggested at the start of this article, nobody actually needs a smart toothbrush.  A manual brush is perfectly fine if used correctly.

At the time of writing, there are still many electric toothbrushes that do not have smart features built-in.  Those without smart features tend to be more affordable.

As time moves on and technology becomes even more affordable, it is very likely smart features are going to be built into the most basic of electric toothbrushes and you will almost be lumbered with the technology whether you actually want it or not.

However, I have seen no instance yet where you are forced to use it.

In some cases, there are limitations by not using the technology, for example, you may not be able to customise modes or change default settings unless you use the app, but the product does still function.

The choice of using the technology or not is down to you.
