Homonym: enamel (Coating)
Enamel is the hard, outer layer that covers and protects our teeth. It is the strongest substance in the human body, made mostly of minerals, particularly hydroxyapatite. Enamel helps prevent tooth decay and damage from acids produced by bacteria and food.
This protective layer is translucent, allowing the underlying dentin to show through, which gives teeth their color. Enamel does not regenerate, so it is important to maintain good oral hygiene and limit sugary foods to keep it healthy. Regular visits to the dentist can help monitor enamel wear and overall dental health.
