“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 all-around

    Duo makes my mouth feel cleaner than any other toothpaste has. It doesn’t get clumpy like some others I have tried and it has a pleasing taste. And of course, I love not using plastic.

    Love these tabs

    I like the flavor more than I thought I would. The clean feeling lasts all night, too! Better than my old toothpaste, which I thought I would never give up.
