Read about the Teethaid scam

The ingredients for this mouthwash aren't listed on most sites where this product is sold, but on one online marketplace, the ingredients included citrus oil and baking soda. And, while yes, there are studies supporting these ingredients' abilities to freshen breath, kill bad germs and even help. maintain a white smile, they certainly can't do it to the extent that many shoppers were led to believe.

So keep reading to find out all you need to know about this hyped-up product, including which claims hold up in the face of science, and which fall flat. And check out our article on the best mouthwashes for products we really do recommend.

What is Teethaid Mouth Wash?

Teethaid Mouth Wash is a foaming oral hygiene solution that you can brush your teeth with and, according to the brand, it helps freshen breath, prevent cavities…and regrow teeth.

Calling it a ‘mouthwash' is a bit of a misnomer, since it's more like a foaming mousse that you apply with your toothbrush. But that's far from our biggest worry about this product.

False advertising has people spending their money on a ‘mouthwash' that promises to be the cure-all for your oral ailments and save you from expensive visits to the dentist.

So we're here to dispel these myths once and for all — in case you had any doubt.

Does Teethaid really work?

Teethaid does not really work in the ways it says it will. Depending on the actual ingredients, it may provide fresher breath and kill germs, but it's difficult to find the real ingredient list.

The Teethaid scam

Teethaid claims that this product will:

  • Help you save money on expensive dentist appointments
  • Get rid of most oral problems
  • Provide drastic whitening results
  • Remove tartar
  • Stimulate the regrowth of lost teeth

Actually, those are just the most outrageous claims — it also claims to restore tooth erosion, eliminate bad breath, and cure mouth ulcers — We only accept one of those as true, can you guess which?

It's definitely easy to make all of these claims without backing them up with solid evidence. And since the makers of Teethaid won't do it, we've done it for you:

Teethaid Claim


Helps you save money on expensive dentist appointments.

Only brushing twice per day and flossing at least once per day, plus regular visits to your dentist can help with you save money on oral care.

Gets rid of most oral problems

See above

Provides drastic whitening results

Only professional teeth bleaching procedures will help you get drastic whitening results. At-home whitening kits can also noticeably whiten teeth as can white strips. Some mouthwashes can be a nice supplement to help you maintain white teeth, and toothpaste with abrasives can help remove surface stains — but no oral rinse or toothpaste will change your tooth color. 

Removes tartar

Tartar is hardened dental plaque, and while some may be removed with water flossing and brushing, the dentist's office is the best place for this.

Stimulates the regrowth of lost teeth

Mouthwashes and toothpaste can contain ingredients that help remineralize tooth enamel, and current stemcell research may lead to the regrowth of teeth. But as of now, there is no way to regrow lost teeth. 

Teethaid ingredients

Whether you look on Amazon or Walmart, it's not clear what the ingredients in Teethaid mouthwash are. In fact, on both sites, it states:

“Plant extracts, help to break down the pigmentation on the surface of the teeth, block pigmentation, keep the teeth bright and white.”

You can find studies that show some research into plants working as whitening aids, and indeed plant-derived ingredients are in many of the products that we do recommend for teeth whitening and oral care in general.

However, these aren't considered the active ingredients — not to mention that Teethaid doesn't specify which plant extracts are used.

AliExpress — an international online marketplace known for its bargain prices does provide a list of ingredients:

Water, Glycerol, Citrus junos extract, Xylitol, Baking soda, Mint, Essence.

So, just in case these are the actual ingredients, we've taken a closer look to find out exactly what each one is for, to determine if they can cause the type of effects that Teethaid claims:

  • Water: Water helps wash away food debris and keep your mouth hydrated (it's also free, and comes from your faucet).
  • Glycerol: Can act as a sweetener, and increase the ability for other components to be dissolved, allowing it to be used in mouthwashes as a substitute for alcohol in some cases, but it doesn't whiten, strengthen, remineralize, revitalize, or re-anything for that matter.
  • Citrus junos extract: This can be used in skincare products, as it is said to have antioxidant and rejuvenating properties (for the skin), however, there were no studies showing evidence of successful use in tooth whitening.
  • Xylitol: Xylitol is used in many oral healthcare products as it is a sugar-free sweetener, and it has been shown to help fight cavities — so that ingredient is legit!
  • Baking soda: Baking soda can be used as a home remedy for mouthwash, as it can help fight the bacteria that causes bad breath — that's 2 for 5!
  • Mint: Some sort of mint is found in virtually all oral hygiene products — it gives your breath that nice fresh feel.
  • Essence: ………………………………….. ¯\_(ツ)_/¯

How to use Teethaid mouthwash

If you were to use Teethaid, the instructions from the brand are as follows:

  1. Apply the foam to your toothbrush
  2. Brush as you normally would

What to use instead of Teethaid?

Anything else? Just kidding — there are plenty of mouthwashes out there that can help you get fresher breath, improve gum health, and support a teeth-whitening routine. Just don't expect any miracles from an oral rinse.

Honestly, if the ingredients in Teethaid are as listed above, it probably won't do any actual harm to your mouth…but best to go with a more trustworthy product.


Don't believe everything you hear — or see on TikTok for that matter. Teethaid oral rinse makes big claims that it simply can't deliver on — no mouthwash could for that matter.

Beware of oral care products that say they will cure all of your ailments — the best way to take care of your oral health is to brush twice daily, floss daily, and visit your dentist as often as recommended by your dental professional.


Does Teethaid really work?

Teethaid doesn't really work in all of the ways it claims to. Depending on its ingredients (which we weren't able to verify) it might help clean your mouth, but it certainly won't give you dramatically whiter teeth, nor will it help stimulate the growth of new teeth.

Is Teethaid legit?

Teethaid is not legit in our opinion, as they tout claims that no mouthwash should make. We recommend going with one of the other tried and true mouthwash brands that we mentioned earlier in this article.

Is Teethaid a scam?

Yes, Teethaid is a scam in that they make claims that simply can't be true for a mouthwash. It won't make your teeth multiple shades whiter, and it won't cure cavities or regrow teeth.

Where can I buy Teethaid mouthwash?

You can buy Teethaid on Amazon, at Walmart, and other online marketplaces. We don't recommend this product, but if you're really keen to try it out, you can find out more on the product page here.

How do you use Teethaid mouthwash?

To use Teethaid mouthwash, you dispense the foam onto your toothbrush and brush as you would with toothpaste. However, we do not recommend this product as there are other much more reliable brands out there.
