Teeth
Teeth are shaped for their jobs: the flat, sharp incisors at the front cut, the pointed canines tear, and the broad premolars and molars at the back crush and grind. A tooth has a crown above the gum and a root in the jaw bone; the crown is covered in enamel, the hardest stuff in the body, over softer dentine, with the pulp of blood vessels and nerves in the middle.
