What is "dentin"?

Dentin is a dense, yellowish substance that forms the bulk of a human tooth, underlying the protective enamel on the crown and cementum on the root. It is composed of mineralized tissue and contains microscopic tubules that house nerve endings, making it sensitive to stimuli such as temperature and pressure. Dentin acts as a cushioning layer, protecting the innermost pulp of the tooth, and contributes to the overall strength and integrity of the tooth structure. When the enamel is compromised, dentin can become exposed, leading to increased sensitivity and potential dental issues.
