   en.wikipedia.org/wiki/Remineralisation_of_teeth

   When fluoride ions are present in plaque fluid along with dissolved hydroxyapatite, and the pH is higher than 4.5, [16] a fluorapatite-like remineralised veneer is formed over the remaining surface of the enamel; this veneer is much more acid-resistant than the original hydroxyapatite, and is formed more quickly than ordinary remineralised ...

   Fluoride has a high tendency to react with the calcium hydroxyapatite Ca10(PO4)6(OH)2 in tooth enamel due to its high affinity to metals. [8] [10] It subsequently replaces the hydroxide group in hydroxyapatite to precipitate calcium fluorapatite Ca5(PO4)3)F. [8] These fluorapatite precipitations scavenge excess phosphate and calcium in the saliva to form a supersaturated solution for ...

   In 1980, the Japanese company, Sangi Co., Ltd., launched APADENT, the world's first remineralizing toothpaste to use a nano-form of hydroxyapatite, the main component of tooth enamel, rather than fluoride, to remineralize areas of mineral loss below the surface of tooth enamel (incipient caries lesions).

7. Hydroxyapatite - Wikipedia

   en.wikipedia.org/wiki/Hydroxyapatite

   In various studies the use of nano hydroxyapatite in toothpaste showed positive results in aiding the remineralisation of dental enamel. [32] In addition to remineralisation, in vitro studies have shown that toothpastes containing nano-hydroxyapatite have the potential to reduce biofilm formation on both tooth enamel and resin-based composite ...
