“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.

    Great product!

    The idea of supplements and tooth cleaning in one is genius! These tablets really taste great, work great, and make my mouth feel fresh and clean. I love that it's a gentle but thicker foam, and they definitely get foamy! I'm a fan for life.

    Works great

    I was skeptical of trying toothpaste tablets, but they work really well and I can feel the melatonin kick in very fast. I have a smallish mouth so I bite the tablet in half and save the other half for later. It also foams up much better than I expected it would.
