Short Description
The hard, outermost layer of a tooth that protects against decay and damage but cannot regenerate once eroded or worn down.
Long Description
Enamel is the highly mineralized, outermost layer of the tooth, serving as a protective barrier against decay, temperature changes, and physical wear. It is the hardest substance in the human body, composed mostly of hydroxyapatite, a crystalline form of calcium phosphate.
Despite its strength, enamel is not living tissue and cannot regenerate once damaged. It can be eroded by acidic foods, excessive brushing, teeth grinding, and decay caused by plaque bacteria. When enamel wears down, the underlying dentin is exposed, leading to increased sensitivity and a higher risk of cavities.
Protecting enamel involves good oral hygiene, fluoride treatments, limiting acidic and sugary foods, and avoiding habits like nail-biting or chewing on hard objects. Remineralization treatments, such as fluoride and calcium-rich products, can help strengthen enamel and slow down demineralization.
