Nano-Hydroxyapatite: The Fluoride-Free Enamel Protector
What is nano-hydroxyapatite?
Nano-hydroxyapatite (nano-HA) is a form of the same mineral your enamel is made of. In toothpaste, it helps remineralise and protect enamel. And it’s widely used as a fluoride alternative.
Fluoride-free, not care-free
Choosing fluoride-free doesn’t mean going without protection. Our formula uses 5% nano-hydroxyapatite to support enamel, so you’re not trading protection for a cleaner ingredient list.
How it works with whitening
Nano-HA and PAP do different jobs. PAP lifts surface stains to brighten your smile; nano-hydroxyapatite remineralises and protects enamel. Together they let our Whitening Toothpaste whiten and care for enamel in one step.
