Recaldent™ is derived from the milk protein, casein. For many years it has been known that milk and its derivatives have a tooth protective effect. Research has shown that this activity is due to a part of the casein protein called Casein Phosphopeptide (or CPP), which carries calcium and phosphate ions in the form of Amorphous Calcium Phosphate (or ACP). Tooth Mousse, the first product for professional use to contain this complex of CPP-ACP (Recaldent™), is the ideal delivery system for bio-available calcium and phosphate ions. CPP-ACP was developed at the School of Dental Science at the University of Melbourne Victoria/ Australia. Recaldent™ is a trade mark used under license. Recaldent™ (CPP-ACP) is derived from milk casein. Do not use on patients with a milk protein and/ or hydroxybenzoates allergy.
