Tooth enamel is made of minerals that work together to protect your teeth. The primary component of enamel is the mineral calcium phosphate, arranged in a crystalline (small crystal) structure known as hydroxyapatite.

The enamel is a thin outer translucent covering of the tooth. Specifically, it covers the visible part of the tooth called the crown of the tooth. The enamel is the hardest substance present in the human body composed mainly of calcium hydroxyapatite and partly of organic materials (proteins).
