Dentin
Definition
The layer of tooth tissue beneath the enamel. Dentin is softer than enamel and makes up most of the tooth structure. It contains microscopic tubes that can transmit sensations, which is why exposed dentin causes sensitivity. Crowns cover and protect dentin.
Related Terms
Enamel
The hard, outer layer of the tooth crown. Enamel is the hardest substance in the human body, protecting the underlying dentin. It cannot regenerate once damaged, which is why cavities and chips need to be treated. Crowns replace enamel's protective function.
Pulp
The soft tissue inside a tooth containing nerves and blood vessels. When decay or trauma reaches the pulp, it can become infected and painful, requiring root canal treatment. The pulp extends from the crown through the root canals.
