What is enamel primarily composed of?

Enamel is primarily composed of calcium hydroxyapatite, which is a crystalline structure that provides enamel with its strength and durability. This mineral is a form of calcium phosphate that is the main inorganic component of the tooth structure, making up about 95% of enamel by weight.

This high mineral content is crucial for protecting the underlying tissues of the tooth against wear and decay. The unique structure of hydroxyapatite allows for the hardness and resilience of enamel, making it the hardest tissue in the human body. Understanding the composition of enamel is vital for dental professionals as it relates to tooth health, disease prevention, and the effectiveness of various dental treatments.
