http://webmineral.com/data/Carbonate-fluorapatite.shtml WebApatite is a mineral found in tooth enamel. When fluoride toothpastes are used, the mineral is converted to fluoroapatite, which is much harder and therefore more resistant to tooth decay. The formula for fluoroapatite is Ca 5 (PO 4) 3 F (molar mass = 504.5 g/mol).
WebTooth enamel is composed of the mineral named hydroxyapatite, Ca5 (PO4)3OH (Ksp = 6.8 x 10^-37). The presence of acids, i.e. acidic fruits, fruit juices or acids that are formed when sugars are metabolized by bacteria, will react with …
