FAQs

Wet your toothbrush and pop a tablet in your mouth. Crunch to break it up into tiny bits. You may feel some bits as you start brushing, and that’s okay. Our natural silk foam will build and reach its peak in about 30 seconds. Brush for at least two minutes. Spit. Rinse if you’d like.

We use a dentist-backed fluoride alternative called nano-hydroxyapatite (nHa), the natural mineral in your teeth and bones that combines with calcium and phosphate to make them strong. Decades of research have proven that nano-Hydroxyapatite is just as effective as fluoride.

Glad you asked. We’re proud of our healthy, satisfying foam. It’s made without the traditional toothpaste detergents and sudsing agents (that cause dry mouth) and naturally activates during the brushing process. The longer you brush the foamier it gets.

Nope! Supplements like vitamin D, vitamin B12, melatonin, and caffeine are absorbed when they come into contact with the tissues in your mouth. This is called mucosal absorption. When you brush with Duo, these supplements efficiently reach your system without needing to be swallowed.

Select your bottles and frequency—we’ll do the rest! Subscribing saves you up to 40% and reduces your carbon footprint with consolidated shipments. After your first delivery, refills will arrive in compostable pouches. You can pause, skip, or cancel anytime.

Duo tablets are manufactured using vegan ingredients in an FDA-registered facility in New York State. Our manufacturing facility is cGMP-certified and every Duo tablet is meticulously screened for quality and safety.
