Formulated by co-founders Stevie Roberts DMD, MS and Robert Johnson DMD, MD, Duo remineralizes teeth, whitens enamel and stops sensitivity at the source. Purifying antioxidants and nourishing botanical extracts promote a balanced oral microbiome.

Free from drying SLS foaming agents and other harsh chemicals used in most toothpastes, our proprietary silky foam naturally hydrates your mouth (hydration is the secret to preventing growth of bad bacteria that cause disease and bad breath).

Duo is at the forefront of bridging oral health with systemic wellness. The mouth is the gateway to all major systems, and the oral membrane is highly permeable.


Many people actually struggle to absorb vitamins and supplements through the gastrointestinal tract. Duo’s toothpaste tablets allow you to absorb essential vitamins like B12 and D directly into your bloodstream as you brush (plus, you can ditch those giant horse-pill vitamins!)

1.5 billion toothpaste tubes end up as trash each year, polluting the earth with toxins from plastic that takes over 500 years to biodegrade.

Reducing single-use plastic is one of the most effective ways we, as companies and individuals, can help the planet.


Duo toothpaste tablets come in apothecary-grade, recyclable glass bottles and refills arrive in compostable pouches.
