Does hydroxyapatite remineralise teeth?
Lab, in-situ, and clinical evidence on whether hydroxyapatite can remineralise early enamel lesions — what is well shown, what is early-stage, and how it differs from fluoride’s mechanism.

Hydroxyapatite and cavity prevention
What clinical trials say about hydroxyapatite toothpaste and cavities — Schlagenhauf 2019 and Paszynska 2021/2023, effect sizes, funding, limits, and how they sit beside fluoride’s evidence base.
Hydroxyapatite and the oral microbiome
How hydroxyapatite interacts with oral bacteria — mainly by reducing adhesion rather than killing microbes — and why short in-situ biofilm findings are not the same as clinical microbiome claims.
Nano-hydroxyapatite vs hydroxyapatite
Nano-HA isn’t a different mineral—it’s smaller particles. See typical sizes, EU morphology rules, and what “nano” on a toothpaste label actually means.
