Made from the same mineral found in teeth and bones, Hydroxyapatite is a proven, safe alternative that’s proven to remineralise and restore tooth enamel. A hero for reducing tooth discolouration, Hydroxyapatite has been the gold standard of oral care in Japan for over 40 years. It is a biocompatible compound and therefore readily absorbed right down to the tooth’s root; unlike synthetic compounds, it reaches the deepest areas of decay and can rebuild enamel on any tooth surface.
