Dentin (/ˈdɛntɪn/) (American English) or dentine (/ˈdɛnˌtiːn/ or /ˌdɛnˈtiːn/) (British English) (Latin: substantia eburnea) is a calcified tissue of the body and, along with enamel, cementum, and pulp, is one of the four major components of teeth. (wikipedia.org)
Dentin consists of microscopic channels, called dentinal tubules, which radiate outward through the dentin from the pulp to the exterior cementum or enamel border. (wikipedia.org)
If cementum loss does occur, the dentin beneath will then be exposed. (colgateprofessional.com)

The cell bodies of the odontoblasts are aligned along the inner aspect of dentin against a layer of predentin where they also form the peripheral boundary of the dental pulp Because of dentinal tubules, dentin has a degree of permeability, which can increase the sensation of pain and the rate of tooth decay. (wikipedia.org)
