“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.

    Ah, sleep. How good it feels !

    I have been telling friends about my new nighttime tooth tablets. I truly believe that the Duo Sleep is helping my body get the melatonin it needs. I have tried melatonin medication and it did not work but the Duo gets the melatonin in my system effectively.
