Enamel

Enamel, the outermost layer of the tooth, is incredibly hard and serves as a protective barrier against wear and decay. It is primarily composed of hydroxyapatite crystals, making it one of the toughest substances in the human body. Enamel is translucent and allows the underlying dentin color to show through, contributing to the overall appearance of the tooth. Despite its strength, enamel can still be damaged by acids from food, drinks, and bacterial activity, leading to erosion and cavities. Maintaining proper oral hygiene and avoiding acidic foods and drinks can help preserve enamel health. Enamel does not contain living cells and cannot regenerate once lost, so prevention and early intervention are key to protecting this vital tooth structure.
