Anatomy
Dentin
Dentin is the dense, calcified tissue that lies beneath the enamel and forms the bulk of a tooth. It is softer than enamel and contains microscopic tubules that connect to the nerve.
When enamel wears away or gums recede and expose dentin, the open tubules can cause sensitivity to cold, sweet, or acidic stimuli. Bioactive materials such as Biodentine are used to repair and protect exposed dentin.
