BOKA: Nano Hydroxyapatite Ela Mint Toothpaste, 4 oz

Nano-hydroxyapatite (n-Ha) is a form of calcium that makes up 97% of your tooth enamel and 70% of your dentin. Because it comprises the primary foundation of teeth and bones, it’s restorative for your smile.

First used by NASA astronauts in space, n-Ha rebuilds teeth without the toxins found in fluoride, making it safe to swallow. (And if it’s good enough for space missions, it’s good enough for us.)
