We've carefully tested the top brushes (including 2023 releases) to ensure our recommendations are accurate and up to date.


We last updated this post in August 2023 after testing the Curaprox Hydrosonic Pro.

Our recommendations

Best overall: Oral-B Pro 2 2000

Best budget: Oral-B Pro 100

Environmental choice: SURI

Best top of the range: Sonicare Prestige 9900

What to look for, what to avoid

We explain these points in more detail later on, but before you make a choice, here are the key things you should know to avoid spending too much or too little. Keep these in mind as you browse our recommendations below and keep reading for more insights from our testing:

  • A 2-minute timer, a pacer and a pressure sensor are the essential features that dentists recommend
  • You only need to spend about $80 to get these features
  • There isn't much to separate Oral-B and Sonicare. They use different cleaning technologies, but either will do a good job
  • Smart toothbrushes generally aren't worth it and add to the price tag

Why it's our main choice: 

The Pro 2 2000 has the essential features we recommend for an electric toothbrush. We rate it as the best Oral-B electric toothbrush, all things considered.

The small round brush head cleans the teeth well. It is easy to manoeuvre into some of the tightest spots in the mouth. If you brush too hard the visible pressure sensor lights up red to warn you.

You can choose between the standard clean mode or the more gentle sensitive mode. There are no icons to let you know which mode is active, but it's easy enough to distinguish between the two.

It has a slim and grippy handle. Be aware that toothpaste residue does build up on the rubber if you don't run it under the tap after use.

The Pro 2 2000 has been independently approved by the Oral Health Foundation, which means it is safe to use, and that it has the benefits advertised.

If you prefer Philips Sonicare, the ProtectiveClean 4300 is equivalent to the Pro 2 2000.

Cheap, but still reliable: 

The Pro 100 brings many of the benefits of an electric toothbrush at an affordable price.

It is a really good option for your first electric toothbrush, or if you're on a tight budget. 

Unfortunately, it does lack a pressure sensor and 30 second pacer.  This means that there are no alerts when you brush too hard, or when you should move from one quadrant to another.  

The 2D cleaning action this brush provides is more than good enough, though. The small round brush head is very good at cupping each tooth and is easily manoeuvred to different parts of the mouth.

Use it correctly and you can expect to remove more plaque than a manual toothbrush. However, you don't get quite the same satisfying deep clean as you do with more expensive models.

With just 1 cleaning mode, this brush is simple to use, which is a definite bonus.  As is the really grippy handle.  There is little chance of this slipping out of your hand, even when wet. This is particularly good for the small hands of children or for seniors with more restricted grip.

From a full charge of the built-in rechargeable battery, you get 8+ days of use. Unfortunately, when the battery is low there is no way to get any feedback on the remaining charge. You don't get a battery status notification like you do with many other models.

A fantastic brush, but more than you need: 

The Prestige has more features than you need, but it is the best smart toothbrush on the market today.

It looks fantastic and feels great in hand.  The smooth touch materials are good quality and easy to keep clean.

We rate it as the best top of the range brush in our Best Sonicare Toothbrush post.

The A3 brush head included in the box gives a really thorough clean — there's no need to switch out different heads for different modes. 

The Sonicare app can tell you precisely where you have and haven't brushed. It will tell you if you brushed with too much pressure and if you scrubbed the teeth. You get visible alerts for these things too.

Despite the complex technology, Sonicare has simplified daily use. During our testing, we didn't find the smart features to be annoying, but we stopped checking the app for feedback after a while.   

The compact USB-C enabled charging case is every bit as stylish as the toothbrush itself. The strap on the case is a little impractical though.

One downside is that the power and intensity buttons require a firm push. They don't give a lot of feedback.

You do pay a premium price for this brush.

If you prefer Oral-B, the iO Series is the equivalent to the 9900 Prestige.

Why we chose it:

Sustainable Rituals (SURI) electric toothbrush is the most environmentally conscious brush that we have seen and used to date.

It isn’t perfect and SURI doesn’t claim to be, but other leading brands don’t come anywhere as close in their environmental pledges.

Slim and stylish, this metal handled sonic toothbrush cleans the teeth well.

It does lack the pressure sensor dentists recommend, but the all important 2 minute timer and 30 second pacer to encourage even cleaning of the teeth are present.

The brush heads are made from plant based plastic (castor oil and cornstarch) rather than the usual petroleum based plastic. SURI does too offer a free recycling programme to help prevent them from going to landfill.

A carbon neutral company, pending B corporation certification, SURI breaks the mould somewhat by having designed this toothbrush to be easily repaired, should it be required. Many modern brushes are not able to be repaired or it is uneconomical to do so.

A premium travel case is included. It not only allows the brush to be charged whilst inside, using the provided USB C cable, but it has a UV-C light to sanitise the bristles.

It also includes a magnetic charging stand that doubles up as a really useful wall mount.

SURI isn’t cheap but is priced fairly for the features on offer and the company credentials. SURI is a UK-based company but worldwide delivery is available.

Our choices explained

The range of electric toothbrushes available is so vast that it can be overwhelming to choose one. To keep things simple, we have narrowed down the options to the choices you see listed above, and will now explain why we recommend them.

Our choice for the best electric toothbrush, the Oral-B Pro 2 2000, is based on the best value for money. It has the features we regard as essential, as well as a few more. It strikes a good balance between features and cost.

The very best brush you can buy is the Sonicare Prestige 9900, which is a top of the line smart toothbrush. We don't recommend this as the top choice because it has far more features than the average user needs. Additional features inflate the price, and you can clean your teeth just as well with the Pro 2 2000 and other cheaper models. 

The Sonicare equivalent to the Pro 2 2000 is the ProtectiveClean 4300. Both models do a great job, but we do find Oral-B's small round brush heads a little easier to move around the teeth and reach the tighter spaces at the back of the mouth.

Oral-B Pro 2 2000 Review 14
The small brush head on the Pro 2000 is easy to move around the mouth

The cost of replacing Oral-B heads is also cheaper compared to Sonicare.

The rubber grip on the front of the Pro 2 2000 handle makes it feel secure in the hand.  The downside is that toothpaste residue can be harder to clean off the textured grip compared to smoother handles like the ProtectiveClean 4300.

The built-in timer and pacer encourage you to brush for the right amount of time, evenly across the mouth. 

The pressure sensor alerts you if you are brushing too hard, which is a cause of gum recession.

The Pro 2 2000 also comes with a travel case included, if you pick the right variant, which is useful for protecting the toothbrush during transport.

All in all the Pro 2 2000 has everything you need in an electric toothbrush and is approved by the Oral Health Foundation. We explain this certification in more detail below.

In terms of design, the 2000 isn't as refined as top of the line models like the Sonicare Prestige and the Oral-B iO, but it is far cheaper.  

You don't need a smart toothbrush.  But, if you want the most advanced and interesting toothbrush, then this is the Prestige 9900.

Philips 9900 Prestige Toothbrush Midnight Blue & Champagne
The Prestige is the most advanced brush you can buy, but it is expensive

It is very expensive, but you do get some very nice extras. For example, the travel case is coated in soft touch materials rather than hard plastics.  It also has a USB cable built into the case. This allows the brush to be charged whilst inside.

Sensors in the handle track your brushing and find areas for improvement. It relays this information to charts and other visuals within the application.  

Nothing about this brush actually cleans your teeth better. Although you may potentially improve your oral care routine due to the information and encouragement the app gives.

If your preference is Oral-B, the iO is the most feature rich model they offer.  It isn't as refined as the Prestige, but it offers some unique elements. These include a colour display and sensor that confirms when you are using the correct pressure.

There is little difference between them, but the Prestige just edges the Oral-B iO in our opinion.

The Oral-B Pro 100 is one of the most affordable options.

Yes, technically there are even more budget-friendly options, but for us their compromises stop them from being strong considerations. 

You may pay a couple of pounds extra for the Vitality than for the really cheap brushes, but you do get a toothbrush from a premium brand, Oral-B. It has good support and its replacement brush heads are easy to find online or in shops.

It actually uses the same brush heads as the Pro 2 2000, but you benefit from the lower initial purchase price of the brush handle itself.

The cleaning action isn't quite as intense and thorough as the more expensive Oral-B brushes, but it is a big step up from a manual toothbrush with most of the benefits.

Other electric toothbrushes we have tested

While only a handful of brushes make it into our list of the best electric toothbrushes, we've put many more to the test.

Over the last few years we have tested well over 130 different models. The majority of these are featured in our reviews and comparisons.

We've explained our recommendations in detail above.  That being said, we know there will be interest in the other brushes we have tested. So we've included a quick overview of them below.

Recent years have seen an increase in the appeal and offering of smart toothbrushes.  As you will have learnt, we don't typically recommend them.  They are expensive, and you don't need one to clean your teeth well.  But, inevitably, the top of the line models come with smart features built-in, out of the box.  

The Oral-B iO and the Sonicare Prestige 9900 are the two leading smart toothbrushes. They are truly the best in terms of technology. But, we encourage our readers to consider the cheaper options, such as the Pro 2 2000, as these can do the job as well. 

The Philips Sonicare DiamondClean 9000 is another one of the premium options.  It is an upgrade over the DiamondClean.  You now have a pressure sensor. This is not a visible sensor, but the handle vibrates when it is activated to alert you.

The Sonicare DiamondClean 9000
The Sonicare DiamondClean 9000

It has a brush head replacement reminder system. An orange light shines on the brush handle when it is time to change your brush head. This is very useful. The negative consequence is the higher price of the brush heads.

The brush also has 3 different pressure settings and 4 cleaning modes. They don't clean the teeth any better. Nor are they essential, but they offer choice.

The 9000 has Bluetooth Smart features. It does not have the position detection and tracking facilities like the Prestige 9900 or DiamondClean Smart.  If the app is used in real-time, you get an on-screen timer only.  Data is synced post brushing. It is displayed on the screen in the form of coloured charts.  This data shows performance for the last 7 days only.  It doesn't allow brushing history and learning as you might expect.

It is a similar story for the ExpertClean from Sonicare.  It cleans the teeth well and has a good box contents.  But, unless you can commit to using the smart features, there are better value options.  Otherwise it feels similar to the 9000, but cheaper.

The 9900 Prestige is the latest addition to the Sonicare lineup of brushes. It offers Bluetooth connectivity. Like the DiamondClean Smart, this does actually offer real-time tracking.  

They fundamentally work the same. But the unique element to the Prestige is that even if you don't use the app in real-time, the handle stores and syncs this data in the background.  You get a mouth map for cleaning, pressure, and scrubbing, something the DiamondClean Smart does not offer. This means you get more meaningful data over time, irrespective of real-time app use or not.

The 9900 is also focused on simplification.  It sounds odd given the brush offers so many features. It's more about getting the job done.  Learning good habits will help you and your oral health in the long term.

It was Oral-B that really pushed smart technology into the toothbrush some years ago. The iO is the latest iteration with even more tech, including a display in the handle, previously only seen on the Oclean X before now.

With the Oclean X, the cleaning performance was great. The display was touch-sensitive and horrible to use.  The iO's display is not touch-sensitive.  Despite this, the X has a lot going for it.  It has a magnetic wall mount, great colour choices and it is affordable.

With the introduction of the Oclean X Pro Elite there is little reason to opt for the older X variant.  The touchscreen has been radically improved and is a delight to use.  It might not be essential, but it adds something to the experience.  The Elite is also super quiet.  In fact, it is the quietest electric toothbrush that we have ever tested, by quite some margin. Oh, and it is a smart toothbrush too. It sends data back to your smartphone to help you track and improve your oral care habits.

The Oclean X Pro Elite is the quietest electric toothbrush we have tested

Older models like the Oral-B Genius AI are extremely capable.  It has more features than you need, but it is more affordable than the iO.  It does away with the clunky position detection technology used by the Genius 9000. The sensors are built into the handle of the Genius AI so there is no need to stand in front of a smartphone camera to track the movements, unlike with the Genius 9000.

Oral-B's app has evolved over the years. But it can be a little confusing. Particularly when there are different configurations for different models.

The Oral-B Smart 7 7000 is a solid mid-range toothbrush.  It cleans the teeth well, has extra cleaning modes, a pressure sensor and 2 weeks battery life. It is neither cheap, nor extortionately expensive.  It is somewhat lost in the range though. Particularly when you consider the slimmer handled Smart 4 4000.  The 4 4000 offers multiple modes, nigh on identical cleaning performance and comparable battery life.  All for less money.

Oral-B has always underperformed in the battery department.  Sacrifices might be expected for entry-level models.  But, around 5 days on a single charge isn't good enough from the Vitality. Admittedly you do have to pay quite a bit extra to upgrade to the Pro 2 2000, but you get extra benefits too (visible pressure sensor, slimmer handle & travel case).

Colgate has offered good value brushes for many years.  They haven't been must-buy products, but they do what they need to.  Oral-B and Sonicare have been better in product quality and cleaning power.  The sonic cleaning action has always felt weaker in the Colgate brushes, and this still applies to the Colgate 250R.  It is cheap, but the battery life and box contents are worse than the 250+ it replaced.  The design is a bit more stylish though.

Mouthpiece style toothbrushes are trying to help with this.  They have a brush head that positions the bristles at the perfect 45 degree angle.  But, in addition, it attempts to clean all tooth surfaces at the same time.  Conceptually it is a great idea.  However, in practice, it does not work.  It fails to reach all the tooth and gum surfaces, leaving lots of plaque behind.  And despite being designed to correct technique issues, there is still a technique to use it.  Worryingly, there is a kids version.  The engaging characters on the brush handle are fun. But it is no replacement to regular toothbrushing.

We don't recommend mouthpiece toothbrushes

Newly tested products & those we are currently testing

We have recently completed testing of SURI. As you may have noted, it is featured above as the most environmentally considerate electric toothbrush to date.

The 2100 Series from Philips Sonicare is a modern and sleek looking affordable replacement for older models. It packs a punch for the price.

Back in January 2022, Oral-B announced the iO Series 10. It has launched in Europe, but we await its arrival in Australia. Truth be told I suspect it will be some time before we see it here, possibly late 2023. Compared to the existing iO9, there isn't much that differs. The key differentiator is the iOSense enabled smart charger. But, if European prices are anything to go by the company is asking a ridiculous price premium for this feature, which is not justifiable.

Oral-B did launch back at the end of 2022, the iO Series 4 and 5. These are 2 more affordable models, ditching the in handle display and magnetic charging stands. They still clean well and benefit from the most desirable iO Series features which includes a quieter brush motor and a pressure sensor that shows when you are using both the correct and incorrect amount of pressure.

As we progress through 2023, at this time we have absolutely no reason to suggest you hold off on buying a toothbrush and wait for what is coming this year. It is better to pick a brush available now and begin using it than it is to wait in hope of the next best thing.

Manufacturers do continually tinker and improve their product ranges, but we are not expecting anything revolutionary. We only have to look at the category of mouthpiece toothbrushes to see that despite many attempts over the last few years we are a little way off perfection.

We will continue to test and review new brushes as and when they do launch.

Buyer's guide: useful pre-purchase advice

Gemma Wheeler
Dr Gemma Wheeler,
BDS (Hons)

With the help of our in-house dentist Dr. Gemma Wheeler, we’ve added useful notes and tips from our research and testing.

No doubt you’ll have one or two particular questions before buying, as did we.

Browse the sections below, and if you can’t find the information you need, please leave a comment at the bottom of this page and we’ll get back to you.

Key things to consider

Below are the three main bits of advice we would give to someone considering a new electric toothbrush.

1. You don’t need to buy an expensive toothbrush

Spending more on a toothbrush doesn’t necessarily mean you are getting a better product. Often you are paying for extra features and functions you will not use. An expensive toothbrush does not clean the teeth better. Many of the best electric toothbrushes come in at under $100.

2. Smart toothbrushes are generally not worth it

They can help to encourage better technique and habit formation, but they are not more effective at cleaning your teeth.

3. Routine and technique are important

Your toothbrushing technique and routine have more impact on your oral health than the toothbrush itself. It's no use having the best electric toothbrush if you don't use it properly.

What to look for in an electric toothbrush

Toothbrushes can come with all manner of features at different prices.

From our testing, the most essential features to look for in an electric toothbrush are:

2 minute timer

A timer helps to ensure that you brush your teeth for 2 minutes each time, which is recommended by dentist and governing bodies around the world.


A pacer helps you to spread your brushing time evenly across all parts of the mouth.

Pressure sensor

Frequently brushing too hard will severely damage your teeth. A pressure sensor alerts you when you are brushing too hard so you can adjust your technique.

You can get a good brush for less than $90

There are a number of types of electric toothbrush, including side to side movements, sonic, and rotation oscillation.

Oral-B brushes use rotation oscillation technology, whereas Sonicare brushes use sonic technology.

There is a small amount of evidence showing that rotation oscillation brushes are better than other types. They reduce levels of plaque and gum disease.

But one review rightly points out that the difference is small. It is unknown whether these clinical trials actually translate into day to day use.

The good news is that rotation oscillation toothbrushes tend to be cheaper.

Apart from this, there is almost no evidence supporting one type of brush over the others. 

However, key characteristics which may benefit you in an electric toothbrush are:

  • a pressure sensor to prevent scrub brushing.
  • a timer to help ensure you are brushing for the full two minutes.
  • a good quality toothbrush head which is changed every three months or when you can see them fraying.

Our number 1 pick in the list above, the Oral-B Pro 2 2000, includes all of these. Many of the best electric toothbrushes come in at under $90.

Spending more money on a toothbrush may provide things like travel cases and better battery life, but these aren't going to actually help brush your teeth better!

We don't recommend smart toothbrushes

No, not in my opinion.

A smart toothbrush is one with Bluetooth technology, which is developing all the time. In the last few years it has evolved from just connecting to a timer to being able to connect to an app on your phone.

Some smart toothbrushes also send reminders when you should change your toothbrush head.

There is no evidence currently available to support the use of a smart toothbrush over a normal electric toothbrush.

As a dentist, I would point out that many of the benefits advertised by a smart toothbrush can be gained more affordably elsewhere, such as by setting a calendar reminder on your phone, or by learning proper techniques from our videos and your own dental professional.

Sonicare vs Oral-B

According to lab testing (1,2,3) the oscillating-rotating technology (used by Oral-B) is better at removing plaque than the sonic technology used by Sonicare.

Whilst the science says the Oral-B is only slightly better than Sonicare, whether this will make much difference in the mouth is unclear. There are other factors at play in the real world, such as comfort during use, noise levels and personal preference, which all influence how well a person brushes with a certain type of brush.

Because of this, you might not want to discount Sonicare and should look into these brushes if you do not like using electric toothbrushes that use oscillating-rotating technology, like Oral-B.

In reality, more research is needed. Our Sonicare vs Oral-B article explores this in more detail.

Is it better to choose an electric toothbrush instead of a manual toothbrush?

Some people will see benefits when using an electric toothbrush instead of a manual toothbrush.

The purpose to toothbrushing is to:

  • remove plaque, which contributes to dental decay and gum disease.
  • remove food debris from the teeth to reduce the risk of dental decay.
  • introduce a fluoride containing toothpaste to reduce the risk of decay.

When asking whether an electric toothbrush or a manual toothbrush is better, the question is really "which one removes more plaque and food debris, without harming the teeth and gums".

Studies (reviewed by Niederman and Yaacob et al ) show that electric toothbrushes are better at removing plaque. They also show that electric toothbrushes help with gum disease.

Despite the clear evidence in reducing plaque, there is no evidence to support the use of electric toothbrushes when it comes to reducing decay.

For people wearing braces, a review of the evidence concluded that there is no reason to support the use of electric toothbrushes for reducing plaque on teeth and avoiding gum disease (although this evidence only covered a period of 8 weeks).

When thinking about the safety of your brush, know that both manual and electric toothbrushes have the potential to cause harm when used incorrectly. An example is causing wear on the outside of the tooth by scrubbing too hard. Evidence has shown that electric toothbrushes are of no greater concern to teeth and gums than a manual toothbrush, and some studies even support the use of electric toothbrushes to prevent worsening tooth wear caused by over brushing.

One other consideration is which one are you more likely to use? A toothbrush that encourages you to brush twice a day for two minutes each time, is always going to be better than one you can't use.

Finally, when thinking about whether an electric toothbrush is better than a manual toothbrush, you will also want to think about the environment. This recent study discussed the greater impact of electric toothbrushes on the environment.

The take home message?

It is a personal choice.

If you are good at cleaning with a manual toothbrush and have no gum disease or tooth wear, then a manual toothbrush is satisfactory. It also has less impact on the environment.

If you struggle getting your teeth clean enough with a manual toothbrush, or if you suffer from gum disease, then an electric toothbrush is a better option for you.

An electric toothbrush can help with gum disease

Yes, electric toothbrushes help with gum disease.

Managing gum disease is all about reducing the amount of plaque on the teeth and under the gums. An important part of this is physical removal by toothbrushing and interdental cleaning.

Multiple reviews  (Van der Weijden Niederman and Yaacob et al) support the fact that electric toothbrushes help with gum disease. More recently, an 11 year long study by Pitchika et al has examined long term successes of electric toothbrush users. These papers have found:

  • electric toothbrushes remove more plaque than manual toothbrushes, in both the short and long term.
  • electric toothbrushes provide a benefit in reducing levels of gum disease (compared to manual toothbrushes) both in the short term (6%) and long term (11%).
  • electric toothbrushes reduce the progression of advanced gum disease, with users having less bone loss.
  • users of electric toothbrushes, and who have gum disease, are less likely to lose teeth.

An explanation of the different toothbrush features

There are lots of features that can be built into electric toothbrushes today.

Not all of them are necessary.

We have grouped the most common features by their importance.

For the high and medium importance features, we have included a brief description. We explain what they do and why they might be helpful.

High importance — essential in any electric toothbrush

2 minute timer

We cannot stress the importance of a timer enough.

Dentists, hygienists and governing dental bodies around the world are in unison that brushing your teeth twice a day for 2 minutes is important.

When brushing your teeth, it is all too easy to get distracted and misjudge time. You can think you have been brushing for longer than you have.

A timer keeps track of how long the toothbrush has been switched on for.

At the end of 2 minutes (120) seconds, the toothbrush will power off or briefly pause the brush motor.

If the timer hasn't gone off, you haven't brushed for long enough.


2 minutes spent cleaning your front or back teeth is no good.  To maintain good oral hygiene you need to clean all the teeth.

A pacer is linked to the 2 minute timer.  

It is designed to encourage you to brush the teeth in the mouth evenly during the 2 minute brushing cycle.

Most pacers work by pausing the brush motor at 30 second intervals.  The pause in the sound and motion of the toothbrush is your cue to move from 1 section of the mouth to another.

Imagine your mouth split up into 4 sections:

  1. Upper right
  2. Upper left
  3. Lower right
  4. Lower left

Spend 30 seconds cleaning the surfaces of the teeth in each quadrant. By the end of the 2 minute cleaning cycle all teeth will have had equal attention.

Some brushes (notably Sonicare) have a pacer set to 20 second intervals.  This results in 6 sections of the mouth. They are as follows: 

  1. Upper right back teeth
  2. Upper front teeth
  3. Upper left back teeth
  4. Lower left back teeth
  5. Lower front teeth
  6. Lower right back teeth
Pressure sensor

We believe a pressure sensor is an underrated feature, particularly for a first time user.

Brushing too hard can damage the gums. Bristles of the brush need only skim the surface of the teeth and gums.

Brushing too hard will also wear away the outermost surface of the tooth. This is what dentists call abrasion. Abrasion itself can cause sensitivity to hot and cold.

Scrubbing harder is not an effective way to remove plaque and debris from the teeth. You and many others may not have known this, because you have never been told or shown how to brush correctly.

A pressure sensor alerts you when you are applying too much force as you brush.

It is a gentle reminder to use a little less force and help you maintain a healthy smile.

Sensors are implemented differently.  

In many instances when pressure is detected, the motor will slow down. This limits the bristle movement and potential damage.

A visible pressure sensor will illuminate to act as a visual alert.  This is common in Oral-B brushes.  Usually, a red light is emitted around the neck of the toothbrush.

Some models, notably Sonicare, will vibrate the brush handle to alert you.

Avoid activating the pressure sensor if you can.

Once the pressure is relieved, the sensor is deactivated and normal brushing resumes.

Medium importance — worth considering, but not critical 

Good battery life

Most electric brushes have built-in rechargeable batteries.  

Over recent years performance and usage time of batteries have gotten better. Most brushes are on par with each other, with an average of around 2-3 weeks use between charges.

The vast majority of batteries in toothbrushes use Lithium-Ion (Li-Ion). Some are Nickel Metal Hydride (NiMH).  

Some brushes will have removable AA or AAA. They can last months. They are not that common and tend to be the cheaper models at less than $25. 

Rechargeable toothbrushes typically perform better and are more cost effective.

Travel case

Even if you are not a regular traveller, a case makes it much easier to transport the toothbrush and brush heads.

When in the case, the likelihood of damage, particularly to the bristles on the brush head is reduced. There is also less chance of the brush accidentally being switched on. Any excess moisture and toothpaste remains in the case and not on anything else that might be in your bag. Nobody likes toothpaste stains on their clothes!

There are certain models that come with travel cases that allow charging whilst in the case. They do not need to be placed on a separate charging stand.


Only ever spend what you are comfortable with.

For some spending $30 will be a lot whilst to others $200 will be cheap.

You do not have to spend a fortune.

A more expensive brush does not mean it is any better at cleaning your teeth.

For less than $90 you can buy an excellent electric toothbrush.

The act of regular brushing, with the correct technique, is more important than what you pay.

Additional cleaning modes

There is little need for extra cleaning modes. The default cleaning mode on a toothbrush is suitable for most users.

If we were to pick an additional mode it would be sensitive.

A sensitive cleaning mode uses less power from the brush motor.  It is more gentle on the teeth and gums.

Model dependent, there can be up to 6 or 7 different brushing modes.

What differs is the power/intensity of the mode and the brushing time.  Very often the likes of a 'deep clean' mode will last for 3 minutes.

For more information, read our Sonicare brushing modes or Oral-B cleaning modes article.

Brushing intensity

Being able to control the amount of power the motor delivers can be useful.

Some models offer the choice of low, medium and high power settings.

If the brush has 1 cleaning mode, it may default to the high setting.

You could change it to the low setting for a less intense clean.

Although the brush motion does not change, the speed of the motion does.

These act as alternatives to cleaning modes.

A brush with 1 mode but 3 intensity settings is in many respects equivalent to a brush with 3 modes.

Cost of replacement brush heads

The cost of replacement heads affects the long term ownership cost. It is worth factoring into your decision. Oral-B brush heads are cheaper than Sonicare.

It's recommended that you replace your brush head every 3 months. If you follow that advice you'll need 4 brush heads a year.

Official brush heads cost anywhere from about $7-12+ per brush head. This can be a lot of money when they will only be thrown away 3 months later. 

You can save money by buying when there's a deal on or by buying in bulk.

In most instances, you have the choice of opting for a third party brush heads. There may not be the same range and the quality may be different. But there are some great options at very good prices.

Do be aware of fakes/counterfeit brush heads which pose as genuine but are often not the real deal. If the price is too good to be true, it probably is.

An explanation of the different brush heads

The brush heads available vary depending on the brand of toothbrush and the model that you choose.

Oral-B, Sonicare and Colgate all offer a range of different types of brush heads.

Each head is, in theory, designed to do a different job.

Sonic brush heads tend to be larger than the small round brush heads found on oscillating-rotating toothbrushes. Sonic heads have an oval shape to them.

The ranges are unnecessarily complicated. There is no definitive evidence to say one head is better than another.

It is best to pick and stick to one style of brush head and use it, rather than to worry about the particular type.

We have dedicated guides for brush heads:

How dental association approval works

There are many dental bodies and organisations around the globe.

In fact, each country will usually have a  panel of leading experts. They usually guide oral health within that country. 

These organisations have similar goals and approaches. For example, producing advice for the general public on how to look after their teeth and gums. Or the recommended fluoride doses.

People look to these for advice on what products they should and should not be using.

The American Dental Association (USA) and the Oral Health Foundation (UK) are 2 examples.

Each has programmes that verify the safety and effectiveness of consumer products.

Consumer oral health care products are independently evaluated. This is to ensure they are safe and that the claims made are proven and not exaggerated.  Reliable scientific evidence is usually required. 

The programmes are designed to give consumers peace of mind and reassurance.

Each programme is run independently.  A manufacturer must apply and submit the relevant data to each organisation. Only once this process has been completed will a product be awarded the 'approved' status of the relevant body.

The ADA issues a 'Seal of Acceptance'. The Oral Health Foundation labels products as 'Approved'.

Although they are separate programmes, they operate with similar policies.  A product awarded the ADA seal would likely be approved by the Oral Health Foundation.

I found with toothbrushes I used that the performance of the brush head decreases with every use. After a week of using a brush head, a slight pressure on the bristles stops the movement of the head. The oscillating shaft in the handle is made of steel, but the moving parts in the head are plastic and wear out after a few minutes of use resulting in so much play that renders it useless after a couple of days. Do you know of a toothbrush that doesn't have this issue?

What brands/models of toothbrushes are you experiencing this issue with? This is not something I have had an issue with.

I call BS on this whole article because Coles sells s ten dollar version that is indistinguishable from my $100+ Braun, apart from not being rechargeable.

Hi Gareth, Thanks for the comment. There are hundreds of different toothbrushes on the market. As much as we would like to, testing them all is an almost impossible task. So we have to come to the conclusions we do as best as we can. We are always trying new products and updating. Please do share a link to the particular product you have so that we can consider it for the future.
