Five Reasons to Switch to Duo
1. Developed by dentists to optimize oral health
Co-founders Dr. Stevie Roberts and Dr. Robert Johnson formulated Duo toothpaste tablets to leverage the latest science for maximum oral and whole-body health. Duo uses all natural ingredients to clean and protect your teeth and gums, including nano-hydroxyapatite for remineralization and antioxidants for overall oral health. Drs. Roberts and Johnson also realized that with a more fun brushing experience, their patients would brush more often. So they designed Duo with great natural flavors and hydrating foaming action to get their patients excited to brush twice a day (or more!).
2. Nano-hydroxyapatite for natural remineralization and whitening
Hydroxyapatite is the primary mineral in your enamel that makes your teeth strong, and nano-hydroxyapatite (nHa) is a microscopic derivative of that mineral. nHa in toothpaste has proven to be highly effective at remineralizing teeth by naturally bonding with your enamel and dentin, reinforcing your teeth’s existing structure. And because hydroxyapatite is what makes your teeth white, nHa naturally whitens your teeth at the source!
3. Glass bottles and compostable refill pouches make Duo the sustainable choice
Duo toothpaste tablets come in apothecary-grade glass bottles, and refills are available in compostable pouches. With 1.5 billion toothpaste tubes discarded every year, and each tube taking 500 years to biodegrade, that is a lot of single-use plastic stacking up in our landfills – not anymore with Duo!
4. Say goodbye to tooth sensitivity without relying on numbing agents
The nHa in Duo toothpastes tablets is a key ingredient to prevent tooth sensitivity. Most sensitivity is caused by exposed nerves in your teeth’s dentin pores, and nHa naturally fills in those pores. No exposed nerves means no more tooth sensitivity! And unlike other toothpaste brands, Duo gets rid of your sensitivity without having to resort to numbing agents. With Duo, you can take on the day with confidence and pain-free!
5. Vitamins and supplements that absorb while you brush – no swallowing needed
Duo utilizes the magic of mucosal absorption to deliver vitamins and supplements directly into your bloodstream while you brush. This works because your mouth is full of capillaries and absorbent tissue that absorb nutrients and bypass the complex filtration systems your body uses to process pill-based supplements. Mucosal absorption gets you your supplements faster, with higher bioavailability and better effectiveness. And because you’re already brushing anyway, Duo means one less thing to worry about. With Duo, you can get more of what you need, when you need it!

- LCLori C.Verified BuyerReviewingImmunityI recommend this productRated 5 out of 5 starsYesterdaySurprisingly efficient
These small tables leave your teeth super clean and I have noticed my teeth are whiter.

Duo works very well. I would buy it again.
- JCJudy C.Verified BuyerReviewingOriginal + 3 BundleI recommend this productRated 5 out of 5 stars1 week agoLove this product!
I love everything about this product starting with the little glass bottles. I've been trying to get rid of one- time use packaging for all my basic products like shampoos, laundry detergents etc. and the glass bottles along with the compostable refill pouches fit this goal perfectly. I've tried other tooth tablets before but I like the taste of these the best. They're minty but not overpowering. I've also been trying to pay attention to the ingredients in products and wanted to know more about the nano-hydroxyapatite in the product. I emailed the company and got a very detailed response from Mike, one of the co-founders of Duo. I will be a customer for life and am ordering starter sets for my grown children to get them started!
- KJKara J.Verified BuyerReviewing360 BundleI recommend this productRated 5 out of 5 stars1 week agoEnjoying this but with bad breath mornings
I think that maybe if you floss, then use mouthwash, then use Duo, then you won’t have bad breath in the morning. But if you forget the mouthwash, then Duo doesn’t seem to have a strong enough mint flavor to account for better breath in the morning. I didn’t have this issue with regular tooth paste. It’s just an adjustment though, because I love the toothpaste itself and do actually think that it has made my teeth whiter already after just one month of use. I love the way it makes my teeth feel. It’s like squeaky clean feeling. I’d recommend it!
