BioMin® Toothpaste Review for Sensitive Teeth and Remineralization

Contributors:  
biomin toothpaste review
BioMin toothpaste is available with and without fluoride

Fed up with having to avoid ice-cold drinks and really sweet foods because of tooth sensitivity? Well, Dr. Collins BioMin® toothpaste could be the answer. Not only is it clinically proven to effectively relieve hypersensitivity in teeth, it also provides long-lasting protection against enamel-eroding acids.

BioMin toothpaste is available with or without fluoride, and they also have some yummy flavors for kids, so you can keep the whole family's teeth strong and healthy. But before you buy it, perhaps you want to know a bit more about the ingredients and how it works.

In this BioMin toothpaste review, we will look at what makes this product different from all the other sensitive toothpastes out there, so you can decide whether it's worth a try. We feature some real user reviews for the adult variants — BioMin Restore, BioMin F and BioMin C — and the BioMin for Kids toothpaste.

So, get ready to be informed!

What is BioMin toothpaste?

BioMin toothpaste has a special formula that provides relief from tooth hypersensitivity while also releasing minerals to strengthen, remineralize, and protect tooth enamel.

To understand why this matters, we need to look at what's going on in your mouth every day. When you eat or drink, especially if there is sugar involved, your teeth get coated in plaque. Plaque contains bacteria that feed on those sugars and emit acids.

Acidic conditions in your mouth are not good for tooth enamel; without proper oral care, it can start to wear away. Although your saliva helps neutralize acids, it can't always keep up with regular snacking.

Ask a hygienist: Why does my tooth react to hot/cold foods?

When you are enjoying your morning cup of tea and you get a sudden jolt of pain, it could be tooth hypersensitivity. There are multiple causes for it including receding gums, a cracked enamel layer, cavities, or enamel wear. 

Now that you know the causes, let's discuss the structure of the teeth to understand it better. The crown portion of your tooth is made up of three layers: enamel, dentin, and pulp. 

Enamel (the outer tooth layer) is calcified, and dentin is made up of tubules and is strongly interconnected with the underlying pulp layer, which is rich in nerves and blood vessels. A strong enamel layer protects your teeth, but a weaker one can expose the underlying dentin, resulting in hypersensitivity. 

Make sure to brush your teeth twice a day with a fluoridated toothpaste and with the correct technique. Save enamel and protect against hypersensitivity!

Dr. Asha Ramesh

When you use BioMin, it's like you are giving your mouth a helping hand to keep acids off your teeth and re-build minerals that have been lost from your enamel.

Bioactive particles in the toothpaste bond with tooth enamel to strengthen the tooth structure, fight acid erosion, and block tiny holes (exposed dentin tubules) that are responsible for tooth sensitivity.

This toothpaste is made by BioMin Technologies Limited, and the technology comes from award-winning research conducted between Queen Mary University of London and the Imperial College of London.

The exact details of how it works involve a bit of science, but the following video explains the basics:

The BioMin™ glasses found in BioMin™ F toothpaste are designed to dissolve faster when lower pH in the mouth is present. For further information about BioMin™ products visit www.biomin.co.uk

Here's a quick overview of what each of their toothpastes does:

  • BioMin Restore: This is only option available for purchase in the US. It is an SLS and fluoride-free toothpaste that will clean and repair sensitive teeth. It shields the dentin — the inner part of the tooth that surrounds the nerves — to provide continuous relief from pain. The essential active ingredient is BioMin® C that when mixed with saliva creates a bio-engineered compound called BIORESTORE™, which has a similar chemical structure to tooth enamel and coats the teeth with a protective biofilm. This is also the only toothpaste to receive FDA approval for sensitivity relief.
  • BioMin F: A low-fluoride toothpaste that protects teeth for up to 12 hours and relieves sensitivity. It is the first and only toothpaste to receive Oral Health Foundation approval (a British authority on dental health) for both sensitivity relief and remineralization.
  • BioMin C: A fluoride-free toothpaste for sensitive teeth.
  • BioMin F for Kids: Based on the same BioMin F technology, it contains 40–60% less fluoride than regular kids' toothpastes but uses it more effectively. It is available in melon and strawberry flavors and is suitable for ages 3+.

You can buy BioMin toothpaste online, including on Amazon. However, you can't buy BioMin C or BioMin F in the USA. You can only buy BioMin Restore.

The versions not sold in the US can be purchased through Amazon in other countries and from online international BioMin stores.

BioMin ingredients

The main ingredient in BioMin toothpastes is a bioactive glass that bonds with tooth enamel and mimics the way the body naturally reacts when you consume acidic foods and drinks. Using glass in toothpaste might sound like a strange thing to do. Wouldn't it scratch your gums and enamel? And what if you accidentally swallowed it?

Well, bioglass is already used in many medical applications, including in teeth fillings, and when it is used in toothpastes, the particles are tiny — too small for you to even know they are there.

In BioMin toothpaste, the bioactive glass particles are about a tenth the width of a human hair. Not only does this mean it has a low abrasiveness score (RDA of 68), but also that the particles can penetrate damaged tooth enamel and fill exposed tubules.

Watch the short documentary below for more information about how bioglass is used in the human body (or skip to 3:30 for the bit about toothpaste):

The specific ingredients differ slightly in the fluoride and non-fluoride versions of this bioglass toothpaste, so let's take a look at these in more detail.

BioMin Restore

BioMin Restore is the only BioMin toothpaste that you'll find on shelves in the United States — this is the product that has been approved by the FDA. It's also the only option for purchase on Amazon US.

Its ingredients are:

  • Glycerin, PEG, silica, chloro calcium phosphosilicate, cocamidopropyl betaine, sodium methyl cocoyl taurate, titanium dioxide, carbopol, flavor, potassium acesulfame

As you look at the ingredient lists of the other toothpastes below, you'll see that Restore has two ingredients that the other fluoride-free option (BioMin C) doesn't have — cocamidopropyl betaine and sodium methyl cocoyl taurate — and one ingredient that BioMin C does have but that Restore doesn't — sodium lauryl sulfate.

Sodium methyl cocoyl taurate and cocamidopropyl betaine replace the sodium lauryl sulfate used in the non-US options. They are considered to be gentler, more natural substitutes to their harsher sulfate cousin while providing the same properties.

BioMin F toothpaste

BioMin F toothpaste addresses two problems that 1 in 8 Americans suffer from at some point in their lives: tooth sensitivity and mineral loss in enamel. Often the two come hand-in-hand, and mineral loss can make teeth more susceptible to decay.

The fact that this toothpaste is the only one so far to have gained approval from the FDA and the Oral Health Foundation for both relief from sensitivity and remineralization says a lot about how effective it is.

“Tooth sensitivity and enamel loss can cause many people a great deal of pain. For those looking for a toothpaste which combats sensitivity and enamel demineralisation, BioMin F is a good and effective option.”

-Dr Nigel Carter, Chief Executive of the Oral Health Foundation

Here is a full list of BioMin F ingredients:

  • Glycerin, silica, PEG 400, fluoro calcium phosphosilicate, sodium lauryl sulphate, titanium dioxide, aroma, carbomer, potassium acesulfame

The fluoride concentration is below 550ppm, much lower than the 1,000 to 1,500 ppm that is standard for most adult toothpastes in the US.

Well, the problem with regular toothpaste is that the fluoride is an added ingredient. Although the concentration starts out high, as soon as you've finished brushing, it gets washed away by your saliva and anything you eat or drink. Within two hours it has lost all effectiveness.

With BioMin F, the fluoride is chemically bound to the calcium and phosphate in BioMin particles. When the particles mix with saliva they form fluorapatite, which sticks to the tooth surface and provides fluoride protection for up to 12 hours. Think of it like the hare and the tortoise: slow and steady protects your teeth for longer.

BioMin F for Kids

Tooth decay in children is a big problem in the US. It's important to minimize sugary snacks and brush their teeth twice a day: once in the morning and again before bed. Regular dental checkups are also key.

But for those days when you forget to brush or they have more treats than usual, using a remineralizing toothpaste for kids can give an extra layer of protection.

biomin technologies toothpaste
Dr. Collins BioMin for kids

With the same formula as the adult toothpaste, BioMin F for Kids releases a steady, low-level amount of fluoride for up to 12 hours after brushing. It contains almost half the amount of fluoride as many kids' toothpastes, which is reassuring if you're worried about dental fluorosis.

BioMin F for Kids is intended for ages 3+. Children should use a pea-sized amount of toothpaste (teach them not to swallow!) and not rinse with water after brushing because that washes away the important toothpaste ingredients.

After age 6, children can switch to adult toothpaste, although they may prefer to stick with the melon or strawberry one for a while! The younger product testers on our team gave these kids' toothpastes a big thumbs-up for taste and texture.

BioMin C toothpaste

Most dental professionals and organizations recommend using fluoride toothpaste, but some people prefer to avoid this ingredient. That's why BioMin has also developed a fluoride-free version — BioMin C toothpaste.

BioMin C ingredients are almost identical to BioMin F except that the fluoride is replaced by chloride:

  • Glycerin, silica, PEG, chloro calcium phosphosilicate, sodium lauryl sulphate, titanium dioxide, flavoring, carbopol, potassium acesulfame

This formula produces hydroxyapatite, which actually works to cover the teeth more quickly than fluorapatite. However, it doesn't give the same resistance to acid as BioMin F.

If you're suffering from sensitive teeth and want a non-fluoride toothpaste that's scientifically proven to work, BioMin C is a great choice.

BioMin vs NovaMin in Sensodyne

You have probably already heard of Sensodyne, a brand of toothpaste that is also made specifically for people with sensitive teeth. Perhaps you have even tried it and are wondering what the difference is between Sensodyne and BioMin? Well, the two products address sensitivity in more or less the same way.

The active ingredient in Sensodyne Repair and Protect toothpaste is NovaMin, a bioglass containing calcium and phosphate. When activated by saliva, it forms a hydroxyapatite-like layer that covers and penetrates enamel. As with BioMin, it essentially blocks the exposed dentin tubules that cause sensitivity.

The main difference is in how the toothpastes release fluoride. With BioMin F, the fluoride is a part of the main ingredient, whereas with Sensodyne Repair and Protect, soluble sodium fluoride is added in. What this means is that BioMin F releases fluorapatite, which is ten times more resistant to acid attack than hydroxyapatite.

Because the fluoride is released over a much longer time period (between 10 and 12 hours), it protects your teeth for longer.

BioMin releases fluoride more evenly and slowly

In addition, the particle size of BioMin is smaller than that of NovaMin. This means BioMin is able to penetrate smaller areas and is also less abrasive on teeth.

In short, Sensodyne is effective at relieving sensitivity, but BioMin F can be even more effective and is a better choice if you want longer-lasting protection from cavities too.

“Before using this product, I would order my Sensodyne with Novamin from Europe, as it is prescription only here in the USA. As Amazon prices skyrocketed 200%, I looked for alternatives and found this toothpaste. I switched, and found that it works exactly like Novamin. My sensitive teeth issues have not come back, and this toothpaste is definitely of high quality. Have used for two months and could recommend to people with sensitive teeth.”

BioMin toothpaste reviews

BioMin has received glowing endorsements from dentists and hygienists who have tried it themselves and seen positive results in their patients.

Our product testers found BioMin F pleasant to use with a minty taste that's not too strong. Here are some of their comments:

“I wouldn't say I have very sensitive teeth, but I have one tooth with a ridge near the gumline which was painful to touch. After a few days of using BioMin F, I realised there was no pain at all when I ran my finger across it!”

“It takes a while to get used to swishing the toothpaste around in your mouth after brushing instead of spitting it straight out. After two weeks of using it, I still forget sometimes.”

“I don't have sensitive teeth, but about 10 months ago I noticed a couple of tiny brown spots on the tops of a molar. I've been using BioMin for about 6 months and I could swear those brown spots have all but disappeared. Of course, when I go to my yearly dental checkup, my dentist will need to confirm that everything's alright.”

Consumer reviews

Hop over to Amazon and you'll see that the BioMin toothpaste reviews are mostly positive, with some amazing ‘before and after' stories. Many users comment that they had tried another popular brand without any results, but within a few days of using BioMin F their sensitivity has disappeared.

“This has been amazing! I prefer the taste over Sensodyne and it seems more gentle too. My teeth aren’t nearly as sensitive, and it seems to have even helped my gums. I’m very happy I took a chance with this.”

MeeMoe, Amazon reviewer

However, some people don't feel that it's worth the higher-than-average price tag. “Tastes great but I can't say it's any better than Sensodyne toothpaste just a lot more expensive,” says one review of BioMin, while another user comments that she uses it every other day, alternating with a cheaper one.

Others think it is definitely worth the price for the results it delivers:

“Been using it for 6 days now (a short time frame admittedly), but already I've seen remineralization over a noticeably rough patch of tooth I've had for 10+ years, making it as smooth as other parts of the tooth. Have not tried this against other toothpastes such as Apagard, but it's a huge difference over the old sodium/stannous fluoride formula. Note that it will leave a glossy feel over your teeth, which is probably a result of the remineralization. Excited to see results over the long term.”

Amazon reviewer

“Look, I’ve struggled with sensitive teeth for almost all of my life and I’ve accepted that it is just part of my life. I’ve spoken to several dentists about it and they always suggest Sensodyne and to not only brush with it but apply it as a paste to the sensitive areas. On a Reddit post, I saw someone mention Novamin and that it wasn’t available in the US. I researched it and found this Dr. Collins toothpaste and how they have their own formulation for Novamin. I couldn’t wait to try it so I ordered right away.

I’m on my 2nd day of using it and it’s been a Godsend. I used to get sensitive teeth even when brushing. When I brush with this paste, I literally have no pain or sensitivity. I drink cold water and have had 0 issues. I can’t wait to try it in frozen treats but I can tell you with 100% confidence that it works for sensitive teeth.

As the directions say, brush then swish the formula and DO NOT rinse your mouth, just spit out the foam after swishing.

I can’t recommend this stuff enough!”

Jeremy, Amazon reviewer

How to use

You know how to brush your teeth, but there are a couple of things you might need to do differently to get the most out of BioMin. Here's what the manufacturers recommend:

how to use biomin toothpaste
Adults and kids should follow these steps
  • Brush before breakfast and last thing at night.
  • Use a pea-sized amount for kids aged 3-6 years old.
  • Tilt the brush at a slight angle and gently brush the outer, inner, and biting surfaces of your teeth using short up-and-down strokes.
  • Be sure to reach right to the back of your mouth and other tricky spots.
  • Brush for two minutes, then swish the remaining foam around in your mouth for a further 30 seconds before spitting it out.
  • Don't rinse with water or mouthwash after brushing — this washes away the active ingredients in the toothpaste before they can get to work.
  • Avoid acidic drinks like coffee and fruit juice for 30 minutes after brushing.

An electric toothbrush with smart technology can help you see whether you're brushing your teeth properly too. But a manual brush will still do the job well, as long as you're using the correct technique. When it comes to brushing kids' teeth, letting them choose a baby or kids' toothbrush with fun colors or characters on it can help with compliance.

BioMin has also created special coloring sheets featuring ‘Bino’ the friendly dinosaur, and a brushing chart to encourage children to brush twice a day. Download them from BioMin's website to get your kids on board with their brushing!

Conclusion

The patented technology used in BioMin toothpaste is not only designed for people with sensitive teeth; pretty much anyone can use it and benefit from stronger, protected tooth enamel. Because of the way BioMin F toothpaste releases fluoride steadily over time, the concentration is less than half that of most adult toothpastes in the US.

However, if you'd prefer to avoid fluoride altogether, you can go with BioMin C. With special flavors for kids too, you can keep the whole family's teeth protected with BioMin.

We hope this BioMin toothpaste review has helped you understand more about the product. If you'd like to give it a try, it's convenient to buy on Amazon, either as a single tube or in a better-value multipack.

Many people who have been suffering from hypersensitivity notice an improvement within just a few days, so it's certainly worth considering if this is something you experience.

FAQs

Does BioMin toothpaste contain SLS?

BioMin Restore, the version available in the US, does not contain sodium lauryl sulfate (SLS), an ingredient that makes the toothpaste foam in many personal care products like toothpaste and shampoo.

However, to keep the foaming properties, this ingredient is replaced with cocamidopropyl betaine and sodium methyl cocoyl taurate — gentler, more natural alternatives.

Is BioMin tested on animals?

No. No animal testing has been used in the development of these products. In addition, BioMin toothpastes are vegan-friendly, as they contain no animal-derived products.

Is BioMin a whitening toothpaste?

No, BioMin toothpastes are not specifically designed for whitening teeth, but some people notice their teeth appear brighter, whiter, and feel cleaner with regular use. If you really want whiter teeth, you could use BioMin alongside a teeth whitening kit. Alternatively, you could try one of these whitening toothpastes instead.

Where can you buy BioMin toothpaste in the US?

BioMin toothpaste may be available in some pharmacies and dental practices, but it isn't widely stocked yet. You may find it easier to purchase BioMin toothpaste online, where prices may be lower too. Click here to view prices for BioMin Restore on Amazon.

What is the active ingredient in BioMin?

The active ingredient in BioMin is BioMin® C. This is mixed with your saliva to create a compound called BIORESTORE™, which has a similar chemical structure to tooth enamel. This enamel-like compound coats teeth in a protective biofilm and prevents further damage to teeth.
