What Are the Causes of an Exposed Tooth Nerve?

Basically, our tooth is composed of three layers; the uppermost layer is composed of enamel, right next to it is the sensitive dentine and the innermost layer, tooth pulp. Both the dentin and tooth pulp are very sensitive and also rich in blood vessels.


If any of the two-layer is compromised, you will have extreme sensitive issues in your tooth like sensitivity while having something hot or cold.
