dental enamel

Dental enamel is the hard, outer layer that covers the teeth, providing protection against physical damage and decay. It is the strongest tissue in the human body, composed mainly of mineral crystals called hydroxyapatite. Enamel forms naturally during tooth development and does not regenerate once lost. Its durability helps teeth withstand biting, chewing, and exposure to acids and sugars from food and drinks. Maintaining healthy enamel through good oral hygiene and minimizing acid erosion is essential for preserving tooth strength and preventing cavities.
