What part of the tooth lies beneath enamel and surrounds the pulp?

Explanation:
Dentin is the tooth tissue that lies beneath enamel and surrounds the pulp. It forms the main bulk of the tooth under the enamel cap on the crown and encases the pulp chamber in both the crown and root regions. Dentin is a living tissue produced by odontoblasts in the pulp and contains dentinal tubules that run from the pulp toward the outer surface, transmitting sensations and nutrients. Enamel sits on top as the hard outer layer, cementum covers the root surface, and the pulp is the soft tissue inside.
