Mouthpiece Toothbrushes Explained

Medically Reviewed By: Dr. Gemma Wheeler

(GDC Number: 83940)

At the moment our recommendation is not to buy a mouthpiece toothbrush. You should stick to a regular electric toothbrush.

We have tested, amongst others, what is arguably the best-known mouthpiece toothbrush, Amabrush, and found that it did not clean the teeth well.

The mouthpiece toothbrush has not yet been perfected and is not an alternative to the current manual or electric brushes available.

Although we have not tested every single mouthpiece toothbrush available, we anticipate them also performing poorly.  In fact, reviews from customers support our suspicions.

What is a mouthpiece toothbrush?

A mouthguard or mouthpiece toothbrush is a new style of dental health product that cleans all the teeth at the same time.

A moulded (often silicone) component is placed into the mouth and bitten into like you might a mouthguard used for sports. We’ve also seen them referred to with the following names:

  • 360° electric toothbrush
  • 360° toothbrush
  • Auto toothbrush
  • Auto brush
  • Automatic toothbrush
  • Mouthguard toothbrush
  • Full mouth toothbrush
  • U shaped toothbrush
  • Self-brushing toothbrush
  • Hands-free toothbrush
  • Gum shield toothbrush

Connecting to a control/power unit that sits outside of the mouth, when powered on, the bristles inside the U shaped mouthpiece clean the front, back and chewing surfaces of both the upper and lower teeth simultaneously.

How do they work?

Each mouthpiece toothbrush works slightly different depending on how the creator has developed and manufactured the product.

The underlying principle and theory is very similar to a regular electric toothbrush.

A built-in power source (the battery) will power a motor when the brush is switched on.  The motor drives a series of brush heads/bristles inside the mouthpiece.

The bristles sweep along the tooth and gum surfaces and clean the teeth in a similar fashion to a regular toothbrush.

However, unlike a regular toothbrush, the design means that all 3 surfaces of your teeth are cleaned at the same time, reducing the amount of time you need to brush for.

Amabrush, one of the brands behind such a product has put together the following graphic to show how it works.

Fewer brushing errors – the human element removed

You can have the most feature-rich and capable electric toothbrush available, but if you don’t correctly position and move it around the mouth, you are not helping yourself.

Brushing for 2 minutes is one thing, but having the right technique is another.

There are recommended ways in which to brush your teeth with an electric toothbrush, but this relies on you, the human controlling the brush, to move and position it correctly to allow the bristles to sweep away the plaque and bacteria.

Despite your best efforts, there will be times where your approach is inconsistent, small areas of the mouth may be missed.  It’s normal, it’s human nature.

A mouthpiece toothbrush, in theory, reduces the chance of error.

The mouthpiece is a fixed shape and size and the bristles located to reach and clean the teeth and gums.

In principle the mouthguard style brush head reduces the variation in the cleaning technique and positioning during each clean, meaning in time you can have healthier teeth and gums because you receive a better clean.

The reality of the situation, however, is that currently, no mouthpiece toothbrush achieves a standard of clean that we can even consider satisfactory. The cleaning performance is well below the standards expected.

Mouthpiece toothbrushes reduce brushing time but clean your teeth for longer

As little as 3 seconds is all that is required to clean your teeth with a mouthpiece toothbrush, but the leading brand within this space, Amabrush, has set the brushing time to just 10 seconds.

Even at 10 seconds that is some 110 seconds less, every brushing session.

I could save myself some 48 days in my lifetime by reducing my brushing time to just 10 seconds.

Now, you are probably thinking I have always been told to brush for 2 minutes and that is right.

120 seconds or 2 minutes twice a day is pretty much a global recommendation.  It’s the best balance between time and effective tooth cleaning.

But when this time was agreed upon by dentists, products like these mouthguard toothbrushes did not exist.

Technological advances have allowed us to reach the point where just 20 seconds of brushing a day could be enough.

You only need look at the 30 Second Smile electric toothbrush to see how significant time reduction is possible.

The mouthpiece toothbrush does — believe it or not — actually brush each tooth surface for longer, despite cleaning your teeth for less time.

How?! Well, allow me to explain.

If you think about how you brush your teeth now.  Although you may brush for 2 minutes at a time, you are not spending 2 minutes on each tooth, in fact just a few seconds.

The average adult has 32 teeth.  Each tooth has 3 surfaces that need brushing.

With 96 tooth surfaces to be brushed (32×3) and a normal brushing time of 120 seconds, that is just 1.25 seconds per tooth surface (120/96).

The BIG difference with mouthpiece toothbrushes is that they brush all 3 surfaces at the same time.

Therefore even placing the new mouthpiece brush into your mouth for just 1.25 seconds would, in theory, be equivalent to what you do now.

However, 2 of the 3 innovators within this space are suggesting a brushing time of 10 seconds.

Who is making them?

In 2017 there were 3 main brands/manufacturers that announced a mouthpiece electric toothbrush.

All 3 introduced and have funded their products via crowdfunding platforms such as Kickstarter and Indiegogo.

Amabrush was the first, with Ufunbrush and Unico following.

Amabrush has to date achieved the greatest level of funding, developed the product furthest and in my mind, presented the best overall package. However, as of June 2019, the company has gone into administration.

They achieved €4,300,000, just shy of 6400%, more than their desired funding goal and had as of early 2019 turned the concept into a reality, with many customers (ourselves included) having received working units.

Why not take a look at each of the promotional videos they created to secure initial investment.

In 2018, Y-Brush was announced and has also been successfully funded.

It looks to be the most serious competitor to Amabrush (now no longer trading).

There is an ever increasing number of companies who appear to be trying to cash in on this evolution in oral healthcare products.

Just some of the other brands we have come across selling mouthpiece toothbrushes include:

  • Otobrush
  • Unobrush
  • Huojo automatic electric toothbrush
  • Anabrush
  • Anself auto 360
  • Chiz toothbrush 4.0
  • V-white

The following are more brands that are selling mouthpiece/auto style toothbrushes, but from my investigation and hands on with some, it appears despite marketing themselves as a new brands, they are just shipping the product made by V-White. You can learn more about how and why this is, by reading my Hibrush review.

  • HiBrush
  • Nuubrush
  • Dentabrush
  • Britebrush
  • WhiterUp
  • Nkdsmile
  • Yessmile
  • Brush Ease
  • Autobit
  • Cyclone Brush
  • JAPAN Kumamoto automatic toothbrush
  • Omnibrush
  • Zhonglihe 360° electric sonic teeth whitening kit
  • GideaTech automatic toothbrush 360°
  • Autobrush

Most concerning is how the majority of these are promoted and sold. Cheap copies are the best way to describe them, with most having no clinical or dental backing and little regard for the quality and performance of the product.

More traditional brands within the dental health space such as Oral-B, Sonicare and Colgate have not announced or launched such products.

I suspect they have been working on such, but until there is significant demand from the public for change, then they will not.

A large proportion of people do not seek the benefits an electric toothbrush brings.

Are they clinically tested and proven?


To date, the mouthpiece style brushes have been conceptualised, pilot tested and refined ready for the general public to start using during 2018.

The brands suggest that they have worked with dental professionals to develop such products to ensure they perform effectively, but it is too early for any serious clinical trials to have been conducted and for the brushes to be compared to current electric toothbrushes.

As the brushes come to market, there will likely be some testing and trials that take place.

However, such trials are expensive to conduct and take time, so we do not expect to see reliable results until 2020 and beyond.

Having myself spoken to many of the product creators, they would not continue with manufacturing and producing a product they do not believe could succeed and deliver beneficial results to the public.

That said, having gone hands on in our review of Amabrush, we are a little concerned at what we discovered.  A clinical trial is simply not necessary. We can tell you first hand that the cleaning experience is below the standard you would expect.

All hope is not yet lost, there are other products to test before writing such an innovative approach off.

Are they better than a regular electric toothbrush?

No, not if you are judging them on their cleaning performance alone.  They are much worse.

However, whether something is better or not is of course personal opinion, it depends on your point of view and how exactly we judge these new types of electric toothbrushes.

Of utmost importance is the clean that they deliver.

To date, none have suggested they would offer a better clean than conventional tooth brushing methods.

Amabrush, for example, had specifically cited that their brush will conform to the BASS method which is a widely recognised approach in tooth cleaning, which shows there is a significant level of importance placed on how well the brush actually cleans.

Sadly, in reality, the moulded mouthpiece does not offer a consistent and high standard of cleaning we expected.  It is not yet time to ditch the manual or regular electric toothbrush.

Only time and testing will really show how good or bad all of these different brands of mouthpiece brushes are.

To be worth investing in, the cleaning experience needs to be equivalent to a manual or electric brush.

Of course, a big factor here is convenience.  The reported time saving could be a big appeal for those that are time-poor.

The brushes are unlikely to offer up the same battery life as a regular toothbrush due to the size constraints, so this could be a downside.

Claims are between 2 and 4 weeks.  Of course, this is just a few minutes of running time compared to 1 hour or more available on most regular brushes.

Amabrush did, however, last much longer in our testing.

Features may be limited — the larger handle of a regular brush allows for more technology to be built-in, but that hasn’t stopped the introduction of Bluetooth into some.

What features do they have?

The core feature is the ability to clean the teeth quickly and effectively, whilst being compact, portable and generally convenient, but each product has its own additional features that make it unique.

Ufunbrush, for example, is aimed more at children being the primary users, with fun stickers being attached to the mouthpiece to make it more ‘fun’ and enjoyable to use.

They are available in a range of colours and with different sized mouthpieces to fit the mouths of children from ages 3+ to adults.

It is the only one to be powered by a removable battery.

Unico will offer different sized mouthpieces as well as a modular storage system with UV sanitiser and smartphone app.  It also has a built in toothpaste dispenser.

Amabrush radically evolved the product and range of accessories due to the high level of funding.

Bluetooth connectivity and smartphone app are a reality, as is a wireless charging stand, travel case, UV sanitiser and more.

At this time it is not a complete like-for-like with regular electric toothbrushes but there is an increasing similarity with features like Bluetooth and wireless charging being offered.

Cheap alternatives and replicas

Hopefully, it is clear already, that currently, it is not worth buying a mouthpiece toothbrush.

We say this having tested what is arguably the best example or attempt at a mouthpiece brush to date, Amabrush.

However, there are many companies trying to tempt you to buy one.

It is quite likely that you will see an advert on Facebook, Instagram or across the internet for what appear to be very cheap alternatives to the Amabursh and Y-Brush products mentioned here.

Quite honestly, from what we can tell these are just companies trying to make a quick bit of cash at your expense.

Whilst we have not tested them all, detailed research shows many are copies or re-badged versions of the same product, made by V-White.

A few of the examples I have come across are:

  • HiBrush
  • Nuubrush
  • Dentabrush
  • Britebrush
  • WhiterUp
  • Nkdsmile
  • Yessmile
  • Brush Ease
  • Autobit
  • Cyclone Brush
  • JAPAN Kumamoto automatic toothbrush
  • Omnibrush
  • Zhonglihe 360° electric sonic teeth whitening kit
  • GideaTech automatic toothbrush 360°
  • Autobrush

The websites selling these are very poor with little information about the brush, how it works and what it offers.  The sites have little or no information about the company who makes them, how to contact them or where they are based.  Many of the reviews appear fake and overly positive.

When you actually find a review from a real customer, they generally have nothing other than bad things to say.

Some products also advertise ‘whitening’ features, which in itself if a warning sign because even if this were to be effective (which it won’t be), it’s a dangerous over-simplification.

The reality is these products are nothing more than cheap, low quality, inferior replicas/copies sold at a fraction of the price.  They do not work and should not be bought.

We are more than happy to praise those that offer something generally good, but unfortunately, we have no evidence to date of any offering something that even comes close.

How much do they cost?

Aside from these cheap copies mentioned above,  at present, the majority of these mouthpiece brushes are not for sale. When you “buy” the product you are funding the developer. You should get a product in return when it is finished.

The cost depends on the brand you go for and the package you select from what is on offer.

Prices start from as little as $60/£45/€50 with the average starter kit being $120/£90/€100

In return for backing their crowdfunding campaigns, most are offering a significant discount on what will be the commercial retail price.

If you want to save some cash, now is the time to do it, but we do not advise investing in a mouthpiece toothbrush at this time.

You can see each campaign and the price using the links below:

If you are thinking that this is expensive compared to a regular electric toothbrush, then yes there is a bit of a premium to be paid, but that is necessary for the advantage and innovation they bring.

Where can I see and try them?

At this time the only way to see and try one is to back one of the crowdfunding campaigns and wait until a finalised commercial product is available and has been shipped to you.

Until finalised production units are available there is no way or place that you can see or try them.  It will likely be a couple of years before we see such products (if at all) on the store shelves.

What do the reviews say?

It is still early days in terms of review for mouthpiece toothbrushes because so few products exist.

The first we reviewed was Amabrush.

We have also tested Hibrush and uFunbrush.

We will be testing other models when they become available.

Of course, there are those previously mentioned cheap alternatives, but we don’t feel we should give time to review these based on what we know.

If you are keen to learn more and see what others say, check out these reviews of Otobrush, you will soon see there is little positive to be said.

Where can I buy them?

At the time of writing the brushes are primarily available through crowdfunding platforms such as Kickstarter and Indiegogo.

Which brush are you backing?

We have an interest in all of these different mouthpiece toothbrushes and would love for all of them to do well and make a name for themselves.

Of course, key to this is being good at what they do.

Amabrush was the first we backed and the first we have reviewed and sadly our expectations were dashed when we went hands on.

Y-Brush appears to be the next challenger, but we need to go hands on to discover whether it has what it takes to compete with a regular toothbrush.

    • Vanessa. I have taken a look at the link you provided.

      For some reason, the images do not show for me to take a detailed look. However, having looked at the website, description, price, etc I would be very cautious and would advise strongly sticking with you Philips Sonicare.

      I fear you might be wasting your money if you were to purchase.

  1. Hi – great article that I’ve come across. I saw this sonic brush advertised ( The modus operandi seems slightly different in that you are expected to move the device back and forth around your mouth. Have you tested or seen this device? Is it effectively the same as all the others you list and therefore not worth the expense?
    I have an oral b electric brush right now.
    Thanks, Chris

    • Hi Chris.

      I have not specifically purchased and tested this product to give a definitive answer.

      However, the images, product description, promotional material and hands-on photos from users suggest to me that it is identical to the V-White/HiSmile brush I have tested.

      Based on what I see I would not advise purchasing this and stick with your Oral-B toothbrush.

  2. Since i purchased this tooth cleaning system for $119CAD, and do not seem to be able to get a refund, I’m making it my mission to tell people that this product is a scam. Any company who does not stand behind their product is, in my opinion, trying to put something past you.
    In this case, the mouthpiece came in a lovely package, has a impressive blue light, makes a bit of a hum when on…..and does NOTHING to clean teeth.
    PLEASE make my $119 have some value by NOT purchasing this product!

  3. Hi, I bought one of these on impulse from an advertising video on YouTube.
    It’s brand name is Sno White.

    Totally useless junk. I tried it for a while and was completely unimpressed.

    I tried to return it for a refund but they hid behind the small print in their t’s & c’s saying that it was not returnable due to hygiene.

    I agree with the original article header. Don’t waste your money on one of these, you’re just throwing good money after bad.

    I’ve now bought a standard electric toothbrush (Oral B) and normal, proper teeth cleaning has resumed.

    This was the first, and will be the last time, I bought something on impulse through an internet based ad.

    • Paul….i got caught in the same scam. 🙁
      I also contacted the company, who basically replied, “sorry you’re not satisfied”. I did not see a Return policy even in small print.
      Even PayPal wouldn’t honour the refund of this purchase. Sure give a bad name/feeling to online shopping.

    • If you bought it in the UK or EU, the product has to be deemed ‘fit for purpose’. If you can prove it doesn’t clean, doesn’t matter about hygiene.

  4. You say these new y / v / mouth piece brushes fall short of expectations but there is no detail… why do they fall short?
    Where is your evidence?

    • Hi Chris,

      These products fall short because they simply don’t clean the teeth.

      Not only can you feel it when you use one, but a plaque disclosing test shows this.

      Just take a look at the following before & after photo. All the pink/purple disclosing agent should be brushed away, but as you can see, there is lots left on the teeth.

      Plaque disclosing test Amabrush

    • Thank you Gerald. I am really sorry to hear that you did not receive your Amabrush. It is a real shame the company has had to fold.

      This is the nature of crowdfunding!

      I do believe with more time and money they could have gotten further with this.

      I try to take the positives and think in the future, these mouthpiece style toothbrushes will become the norm.

    • Ian.

      It depends on the particular mouthpiece toothbrush. Some have their own whilst others can or will be able to be used with regular toothpaste.

  5. Nice article.
    As for the mouthpiece toothbrush, it is not clear how you position them near the gum line the way you definitely can do (control) with any other toothbrush.

    • Hi Liviu,

      IN most instances, the mouthpiece should fit nicely around the bottom and top row of teeth and the bristles should be perfectly angled to the gumline to brush them correctly.

      That said, all have a certain amount of flexibility and wiggle room if you like so that you can move the mouthpiece around to achieve the fit and clean you would like.

  6. Been thinking about backing one of these for a while; I’m less concerned with time saving and more with getting my teeth properly brushed, which I honestly rarely do. The price points on all of them are pretty steep for basically untested products, but that’s the gamble with any crowdfund project I guess.

    In any case, great article! Basically put everything we know about this new teethbrushing technology in one place, really helped me make up my mind on which to back!
