“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.

    Good for your teeth and good for the environment

    I've been using these Duo tablets for a week or two and I love them. I'm letting my husband finish the last of our toothpaste in a tube and then he will switch over as well. No more tubes going in the landfill, no more chemical fillers; just a cute little brown bottle and recyclable refill packages when we need more.
