Best Answer

Teeth are made up of 3 hard tissues and 1 soft tissue.

The hard tissues are:

  1. Enamel - The hardest tissue in our body; has a hardness value of 350-500 KHN (Knoop Hardness Number)
  2. Dentin - Hard tissue which is harder than bone but not enamel. Hardness value is 60-70 KHN. Dentin forms bulk of the tooth.
  3. Cementum - Hard tissue which is similar to bone but is avascular (without blood supply). Hardness value is similar to bone - 50-55 KHN.

The soft tissue of the tooth is pulp, which is highly vascular and essentially comprises fibroblasts, collagen fibres, blood capillaries and nerves.
