Dentin is found underneath the enamel surface of the tooth and underneath the cementum that forms along a tooth's roots.

Unlike enamel, exposed dentin is highly susceptible to the bacteria that cause dental cavities and can cause tooth sensitivity. Cementum.
The bulk of the tooth is composed of dentin. The dentin of the crown is covered. by enamel and the dentin of the root is covered by cementum.
