You can't regrow lost enamel — but you can repair it at the surface. Here's the honest science of what rebuilds enamel, what can't be undone, and the daily fluoride-and-hydroxyapatite routine that does it.

Enamel does NOT grow back — it has no living cells, so once it is physically gone it is gone forever. But enamel loses and regains mineral every day, and you can tip that balance: you can re-harden softened enamel and reverse an early white-spot lesion, even though you can never remineralise a cavity.
