Inside a Tooth

A tooth has a hard outer layer, a softer layer under it, and a living center. Roots hold the tooth in the upper or lower jaw.

In the picture

  1. Enamel: the hard white outer covering of the crown.
  2. Dentine: the yellow layer beneath the enamel.
  3. Pulp: the living center with nerves and blood vessels.
  4. Root: the part that anchors the tooth in the jaw.

Examples

  • Biting into an apple presses on the hard outer layer of a tooth.
  • A cold drink can cause a sharp feeling if the living center is exposed.
