Origin: Naturally occurring mineral that is the main component of bone and teeth. It has the formula Ca5(PO4)3(OH), but it is often written as Ca10(PO4)6(OH)2 to show that the unit cell contains two entities.
- It helps remineralize and restore the enamel, which is the hard outer layer of the teeth that protects them from decay and sensitivity.
- It forms a protective layer on the enamel and the root surface, which can reduce the risk of plaque formation and tooth erosion.
- It prevents bacteria from attaching to the enamel, which can cause cavities and infections. Unlike fluoride, which kills bacteria, hydroxyapatite does not affect the oral microbiome, which is the balance of good and bad bacteria in the mouth.
- It decreases tooth sensitivity by filling the tiny cracks or tubules that expose the nerves in the teeth. This can make the teeth less reactive to hot, cold, sweet, or sour stimuli.
