tooth enamel

Tooth enamel is the hard, outermost layer of your teeth that protects them from damage and decay. It is the strongest mineral substance in the body, primarily made of calcium and phosphate. Enamel acts as a barrier against acids and bacteria in the mouth, which can cause cavities and erosion. Although enamel is highly durable, it can wear down over time due to factors like poor oral hygiene, acidic foods, and grinding. Once damaged or eroded, enamel does not grow back, so maintaining good oral care is essential to preserve its integrity and keep teeth healthy.
