“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.

    Sleep Duo

    I'm glad I tried this product out. It helps me fall asleep gently and quickly. This is a new essential part of my sleep routine. The lavendar is a tad strong, but I enjoy it. Happy brushing!

    Way better than other toothpaste tablets!

    My dental hygienist can’t stop oohing and ahhing over my teeth since I started using these tablets. They foam up so nicely compared to other toothpaste tablets. I subscribed for auto shipping because I don’t want to ever run out.

    Love the packaging!

    I already had the glass bottles, so I am thrilled with the reduced waste on this packaging.
