Question

what is the composition of human tooth enamel

Answer 1

This inorganic material is mainly composed by a calcium phosphate related to the hexagonal hydroxyapatite, whose chemical formula is Ca10(PO4) 2(OH) 1. X-ray energy dispersive spectroscopy (EDS) analysis of enamel and dentin also indicated the presence in small quantities of other elements such as Na, Cl and Mg 2.

Answer 2

Calcium Phosphate is the composition of human tooth enamel and that is why it is the hardest substance of the human body.
