Meet the super ingredient that’s quietly changing the future of oral care — Nano-hydroxyapatite (n-HAp) n-HAp is a synthetic version of the mineral that makes up your teeth. It mimics natural enamel, filling microscopic gaps, rebuilding the tooth surface, and sealing exposed dentine to reduce sensitivity. Clinically proven to soothe, repair and support your smile in as little as two weeks — all without disrupting your mouth’s healthy microbiome. And it’s the hero ingredient in our new toothpaste — Restore.
