“What you brush 
with matters.”

Tooth enamel cannot repair itself from within, which means your toothpaste has an important job to do. We packed Duo with proven ingredients like nHa to remineralize teeth and promote vibrant oral health. Developed by dentists, better for everyone.

    I am so glad that Duo has refills available! I love the easy travel bottles and having refills available is so convenient. I have tried other toothpaste tabs but find Duo to be easier to chew. Also, they do not contain fluoride but still provide cavity protection !!

    Thank you, Duo ❤️

    Love it!

    These tablets are the best! The only thing I would like is to have refills with no new bottle.
