What is tooth enamel known as?

Tooth enamel is recognized as the hardest substance in the human body due to its unique composition and structure. Enamel is primarily made of hydroxyapatite, a crystalline calcium phosphate, which gives it exceptional strength and durability. Its hardness is crucial as it protects the underlying structures of the teeth, such as the dentin and pulp, from wear, decay, and external forces during chewing.

The hardness of enamel allows it to withstand significant pressure and friction from food during mastication, making it essential for effective chewing and maintaining overall oral health. Its resilience is a key factor in preventing the effects of cavities and erosion caused by acids from food and beverages.

This characteristic differentiates enamel from other substances in the body, with the significant emphasis being on its mechanically protective function rather than any perceived fragility or softness, which would not accurately reflect its capabilities.
