The hardest substance in our body is tooth enamel. 1. Name the chemical compound present in the tooth enamel.

Tooth enamel is primarily made up of hydroxyapatite, a crystalline structure composed of calcium phosphate. This amazing compound provides the enamel with its incredible strength and durability, making it capable of withstanding the forces of chewing without easily wearing down. Did you know that tooth enamel is incredibly thin, usually only about 2.5 millimeters in thickness? Despite its hardiness, it's also quite susceptible to erosion from acids found in food and drinks. Maintaining good dental hygiene and a balanced diet can help protect this vital layer and keep your smile shining bright!
