It’s called nHap. It stops sensitivity at the source, and it's changing how we think about oral health.
(DDR) — If you suffer from sensitive teeth or are simply tired of generic supermarket pastes that don't seem to do anything, you aren't alone. For decades, the standard answer has been "more fluoride."
But a new standard has emerged in 2026, and it wasn't invented in a boardroom—it was originally developed by NASA to help astronauts repair their bones and teeth in zero gravity.
Your teeth are made of enamel, which is 97% hydroxyapatite. When you eat acidic foods, you lose those minerals (demineralization).
nHap is a bio-mimetic mineral. Unlike fluoride, which just sits on top of the tooth, nHap actually bonds with your teeth to fill in the microscopic tubules that cause sensitivity. It essentially rebuilds your enamel from the outside in.
We tested dozens of brands claiming to use this technology. However, many use cheap "aggregates" that are too large to actually penetrate the tooth surface.
One product stood out for its high concentration of medical-grade nHap and clean ingredient profile.
Rated #1 for purity, particle size, and whitening capability without abrasion.
