Davids | NASA Nano-Hydroxyapatite Natural Toothpaste

Discover the breakthrough toothpaste powered by NASA-developed nano-hydroxyapatite technology! Originally created to help astronauts repair their teeth after time in zero gravity, this revolutionary mineral is now transforming natural oral care on Earth.

Nano-hydroxyapatite makes up 97% of tooth enamel and works to rebuild tooth structure by sealing micro-cracks and reinforcing weakened areas. The HYDROXI™ Enamel + Whitening formula provides clinical-grade enamel support while gently removing surface stains, and the Sensitive + Whitening version fills microscopic tubules to block sensitivity at the source.

Made in USA with 98% domestic ingredients, EWG VERIFIED™, and housed in recyclable metal tubes. Fluoride-free, SLS-free formulas with premium botanical mint flavors transform your daily brushing into proactive treatment for stronger, healthier teeth.
