Dentist Journal

Why does a cracked tooth hurt?

The crack exposes the inside of the tooth (the ‘dentine’) that has very small fluid filled tubes leading to the nerve (‘pulp’) of the tooth. Flexing of the tooth opens the crack and causes movement of the fluid within the tubes. When you release the biting pressure the crack closes and the fluid pressure simulates the nerve and causes pain.
