The mineral
Your enamel, rebuilt.
Hydroxyapatite is the calcium phosphate mineral that makes up 97% of your enamel and 70% of dentin. It's not a synthetic substitute — it's what teeth are already made of.
For decades, Japan has recognized it as a clinically proven anticaries agent. Now it's becoming the global standard for fluoride-free oral care: biocompatible, safe if swallowed, and effective at rebuilding the surface layer you lose every day.
That's why we built One+ around 10% nano- and micro-hydroxyapatite — the concentration where remineralization actually shows up in the data.
01 Is hydroxyapatite actually as effective as fluoride?
Yes, when the concentration is right. Decades of Japanese clinical data — where HAp has been a recognized anticaries agent since 1993 — support 10% as the threshold for measurable remineralization. We meet it; most other brands don't.
02 Why nano AND micro hydroxyapatite?
They do different jobs. Nano-HAp is small enough to enter dental tubules and address sensitivity at the nerve. Micro-HAp coats the surface and rebuilds the visible enamel layer. Using both is how you get the full effect.
03 Can children use it?
Yes. Hydroxyapatite is biocompatible and safe if swallowed — one of the reasons we chose it. We still recommend a rice-grain amount for kids under 3 and a pea-sized amount thereafter.
04 What's the actual ingredient list?
