Myst Toothbrush Review – Proceed with caution

Myst Automatic Toothbrush ⚠

We DO NOT recommend the Myst toothbrush.

We strongly advise you proceed with caution before buying this product.

It will be better for your dental health if you buy a regular electric toothbrush and learn to use it properly.

In the interest of full transparency, I have not purchased or physically had hands-on with this mouthpiece toothbrush. I have tested many similar products, none of which perform to the standards expected.

I have chosen not to test Myst personally.

This is because when researching the product and the websites selling it, far too many alarm bells go off in my head.

The promotion and claims of this product are too good to be true in many instances.

I wish not to fund the companies behind this product. It is not fit for purpose. They are promoting products that can pose a risk to a people’s oral health.

This is further backed up by the countless comments and emails we have received confirming that this automatic toothbrush is simply no good.

Some have previously suggested that I and the team here at Electric Teeth are paid to vote against such products. This couldn’t be further from the truth. Please do refer to our ethics policy. We don’t accept sponsorship and genuinely care about people making their own, informed decisions about their oral care.

We all desire an easy and convenient solution to toothbrushing.  I am a massive advocate for innovation.  But Myst and their mouthpiece toothbrush is not the answer.

Myst mouthpiece toothbrush

I have tested hundreds of electric toothbrushes and know what does and does not work.

As yet no company has mastered the mouthpiece style toothbrush, even with millions of $/£ investment.

SymplBrush is the best mouthpiece I have tested to date. Yet, it still isn’t a suitable alternative to your regular manual or electric brush.

I have written extensively about my experiences with these products.

Of course not having purchased and tried it myself, I am limited in the first-hand comments I can make.  But, here are the reasons I simply can’t recommend it and won’t be testing it.

Please do make your own decision based on what I share.

If you would like to be notified when we can recommend a mouthpiece toothbrush, sign up to our toothbrush technology email.

Dentist approved – but no mention of the dentist

The Myst press releases and marketing materials mention it is dentist approved. They fail to say who that dentist in most instances.

I have seen a reference to Dr Jim Collins DDS.  Apparently, he says “the beauty of MYST is that it’s mistake proof. It provides 100% coverage every time. You don’t have to worry about brushing at a certain angle or getting to those hard-to-reach areas — MYST™ XRT™ does everything for you.”

Dr Collins appears nowhere on Myst’s website which sells the product. If he is quoted in the press releases you might think he would be on their website too?!

I am unable to determine who exactly Dr Collins is. There is no reference to his location within the USA, his practice and his experience.

I can find no other details anywhere of any reputable dentist recommending this product.

First automatic toothbrush

Myst claims to be the first automatic toothbrush.  This isn’t true.  The first automatic toothbrush of this type was Amabrush.

Myst did not come onto the scene until several years later.

XRT – Expansion Radius Technology

Myst XRT Technology

According to Myst their toothbrush has technology known as Expansion Radius Technology or XRT.  

It delivers a complete cleaning of all the teeth simultaneously.  No spot is left untouched or uncleaned as the entire surface area of each tooth is brushed.

XRT allows you to receive automatic, high-quality cleaning for all your teeth in the comfort of your own home.

I have been testing toothbrush products since 2015 and have never heard of XRT technology.

Amazingly all references I can find to it, link back to Myst.  Yet there is no clear information on what it is, how it works and the science behind it.

What exactly is expanding?

Claims of award-winning

Articles like this claim Myst is ‘Award-Wining’ yet fail to mention what award it has won.

1 size fits all brush head

There is just a single style and size of brush head.  This is supposed to be a one size fits all.

To date, no mouthpiece toothbrush has mastered this.  They are either too big or too small.

I am not sure how Myst are accommodating for all the different sized mouths with just 1 silicone mouthpiece.

When I have tested other silicone brush heads like this, they have failed to reach the gumline.  The gumline is the most important area to brush.

Sold via Infomercials

You don’t see Myst stocked in your local dentist’s office or in your local pharmacy.  It isn’t sold on Amazon or other popular online stores.

Instead, the main sales technique seems to be highly targeted online advertising.  

The advert is usually a video. Essentially an infomercial that is a few minutes long.

Much of the footage is very generic, or stock as it is otherwise known.  You don’t see much hands-on with the Myst toothbrush itself.

The voices can sound quite robotic and often there are some bold and unsubstantiated claims.

These are designed to capture you and sell the product in the moment.  A reactionary purchase.

4 websites to sell one product

Myst have put out press releases to promote their product, which includes URLs for no less than 4 different websites.

What company has 4 different websites selling the same product?

It might be different if these other sites were resellers, but they are not.

Their own Facebook page also lists the 4 different sites:

  • https://buymystnow.com/
  • https://mystoralcare.com/
  • https://mystsmile.com/
  • https://mysttoothbrush.com/


The prices are all over the place.  

As a general rule, you are probably going to see this offered for $99.

However, when you go to buy it, you get additional offers.  This isn’t uncommon with online stores.

But if you buy 3, you can actually get 2 free, making them just $59 each.  That is pretty impressive.

It seems an odd deal for a toothbrush.  That is a $40 saving on retail.

Wouldn’t a more logical option be to offer replacement brush heads?

Replacement brush heads – Lack of

I don’t know how you buy replacement brush heads.  Mysts own website appears not to sell them.

Dubious online content

There are many websites writing about Myst saying how good it is.  However, you only need to look at some of the websites and the language used to realise these sites are perhaps not what they seem.

The English used is often poor.

The so-called ‘reviews’ are all very similar with limited hands-on images and any real personal opinion shared.

There are no plaque disclosing tests to show how well the teeth were cleaned.

To me, much of the content looks fake. Or it is sponsored content, whereby the sites have been paid to write or host this positive style of content.  


The company has one of the more unusual returns policies I have seen in all my years operating online.

As part of the sales process, they offer a 30 day money back guarantee.  This is great.

However, this only applies to unopened and unused products.  These details are hidden within their terms of use page.

To me, it isn’t a money back guarantee, if you haven’t actually been able to use the product.  I would argue this implies you can use it and if not happy you can return it.

Oral-B and Sonicare offer similar schemes, but as you might expect you can use the products during this time.  This way you know if you want to return it or not.

I have read of many then struggling with this returns procedure even if they haven’t opened or used it.

It is based on V-White toothbrush

A legitimate online business approach is something called white labelling and dropshipping.

These are 2 slightly different techniques to make money online.

Dropshipping is where you sell someone else’s products on your own website. You don’t own or hold the stock yourself.  Once you have an order from a customer, you arrange for it to be shipped from the seller/warehouse that does stock it.

White labelling is where a company produces a product, but then puts your own logo’s and customisations onto the product.  This means the original product can essentially be sold by many different companies, under different names, but the underlying core product is the same.

Myst seems to have taken both approaches.  

In the past, they were selling a product that was identical to a product called V-White.  This is one mouthpiece toothbrush I have tested.  It is the same toothbrush that went through a clinical trial.  

The trial concluded the use of a U shaped toothbrush like V-White was no more effective than not brushing your teeth at all!

Old Myst website screenshot with V-White product

In more recent times, they seem to have moved to a white labelled solution.  So the product you receive is branded Myst.  From what I can tell it is the same as this product here, sold on AliExpress.


All the reviews on their website are 5*.  

Yes, any brand is going to want to promote the best reviews, I get it.  But, most companies will show a few less positive ones for balance.

Even the best products get the odd 3* rating.

Too good to be true? You decide.

Why not check out their reviews on Trustpilot.  Because of their multiple websites, there are multiple review pages:

Feedback from others

Here are a selection of comments I have received from others:

Kurt says:

Do not buy the Myst Toothbrush. It does not work and if you open it to find out for yourself you can not return it. Total waste of money and at SCAM

M Denton says:

Definitely a scam!!  I wish I had done my research before buying.  Video seemed legit.  Not only did it not clean my teeth as promised, it stopped working in 2 weeks!  Don’t fall for the money back guarantee, which tends to lend credibility.  However, that only works for credible companies.  Save your money and time and avoid the frustration of trying to get your refund!!!  AVOID THIS ONE.

Desiree says:

I got trapped into the myst infomercial and I stupidly bought it without doing research and of course the first try I noticed it didn’t clean my teeth whatsoever, I even did 4 cycles… still a filthy film on my teeth were left. I asked for a refund and they have been giving me every excuse from they can’t except it back because of Covid to sending me these generic terms saying just by clicking on the website I agreed to the terms themselves, both of them I called them out on because I said for one they were hiding behind Covid because it wasn’t like they could resell it.. it’s a toothbrush! And second the just by clicking on the website you “agree to the terms” which are not even listed anywhere and doesn’t even mention no money back etc. they’ve offered a 50% refund and I said no I want a full refund, they’re selling a defective product and I sent them the link to this website to show them they aren’t hiding. I plan to wage war against them, they’re stealing money from people at a time when people can’t afford it and risking their health and dental care.

DrTina says:

We had purchased two Myst devices and paid full price! They didn’t last more than a couple of months! Plus we still had to brush our teeth manually since this device did NOT clean our teeth as promoted!

RJ says: 

I wish I would have seen this video before I purchase the product, he’s right it doesn’t work.

Michael says:

I was foolish enough to buy the MYST without reading the return policy. They claim that they cannot receive the product back once it has been opened. However, that really doesn’t matter because they do not answer or return my phone calls. Their website, which is basically a “purchasing” site reveals a side window indicating that another person (victim) has just purchased their product. They claim that you have a 30 day return option but in a confusing barrage of print note that it must be unopened. There are very few people who will not open what they have ordered and decide to return it unopened. As far as I am concerned the “MYST” sellers are scam artists. I’ll bet that they don’t even use the product themselves. Why is our world so full of such people?
