  1. 1. The hardest, white outer part of the tooth. It is mostly made of calcium phosphate &, a rock-hard mineral
  2. 2. The softer, living inner structure of teeth. Blood vessels and nerves run through the pulp of the teeth.
  3. 3. These teeth erupt at around age 18, but are often surgically removed to prevent displacement of other teeth.
