More people, including dental hygienists, are switching to nano-hydroxyapatite (nHA), a fluoride-free toothpaste ingredient made from the same mineral as your enamel. Here's why.
1
A university lab saw the difference under a microscope
*Independent laboratory study conducted in 2026. Results observed on dentin samples under microscopic imaging after 3 lab applications of Mouthology 10% nHA toothpaste. Results in a laboratory setting may not reflect individual use.
In an independent university lab study, dentin samples went from 91% exposed tubules to 18% after just 3 lab applications of Mouthology.* Tubules are tiny channels in the layer under your enamel.
Hydroxyapatite is the primary mineral in your enamel. We use 10% nano-hydroxyapatite, the concentration used in published research, to help remineralize* and support enamel.
