Dentin is the part of the tooth below the enamel that is made from calcium, root canal and pulp chamber. It is made up of calcified tissue, along with enamel, cementum, and pulp all of which are major parts of a tooth. The enamel is on the outside of the tooth or “crown” and the cementum is the root and all is surrounded by the pulp. This is called the primary dentin.
