“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.

    Interesting Idea

    I love the novelty of this and the added benefits to ordinary toothpaste. I’m still getting used to chewing up a paste, but it’s fun to switch it up. I’ll try out this routine for a few months. So far liking it alright.
