High-Tech Sensitive Toothpastes

Technology developed by NASA can be found in the newest launch from Davids Natural Toothpaste, the Davids Sensitive+Whitening Hydroxyapatite Toothpaste. This high-performance sensitive toothpaste uses an innovative ingredient, nano-hydroxyapatite, for the purposes of repairing enamel and relieving sensitivity. Nano-hydroxyapatite (n-Ha) was developed exactly for these purposes by NASA to help astronauts operating in a zero-gravity environment in space.

The proprietary formula is said to "repair the tooth as hydroxyapatite is deposited inside the passageways to the nerves (tubules), where the bio-active material bonds to the inner tooth surface to plug the tubules and stop sensitivity at its source." Unlike some sensitive toothpaste products that actually use nerve-numbing potassium nitrate, this drug-free alternative actively repairs teeth.
