Enamel

What is Enamel?

The hard, non-living outer layer that covers the crown of a tooth. It is the hardest substance produced by the human body and resists the wear of biting and grinding, but because it contains no living cells it cannot repair itself once it is worn away or damaged.

This definition is part of the Human Nutrition chapter in Cambridge O Level Biology.
