Unlike most sensitive toothpastes, which work by either numbing the nerve or slowly blocking tiny channels inside the tooth over days or weeks, AeroGraft quickly seals exposed tubules (tiny hollow canals that make up the interior structure of human teeth) while releasing calcium and phosphate ions to form a protective mineral layer on the tooth surface.

This title could not look more like an ad. I'm not saying it is an ad (full disclosure, I didn't even click the link), but if a company is trying to market their new toothpaste with "natural" ingredients sprinkled in, this is exactly the title they'd go for. The title doesn't even make a single claim of anything new being done.

Now do natural brushes.

Wondering if this is just nano hydroxyapatite with aerogel just for kicks, or if there is meaningful difference / improvement.
