Dentin Definition by Healthwise:
Dentin is the middle layer of a tooth. It is made of hard minerals and protects the pulp (the inner core of the tooth) from external conditions such as heat and cold.
Dentin is covered by enamel above the gumline (the crown of the tooth); dentin in the root of the tooth is covered by hard connective tissue called cementum.
