When you bite down do you feel a sharp pain? It quickly disappears and perhaps you ignore it. You avoid certain foods or chew on one side of your mouth. Does this sound familiar? You may have a cracked tooth!
A cracked tooth hurts because the pressure of biting causes the crack to open. When you stop biting, the pressure is released and a sharp pain results as the crack quickly closes.
Even though the crack may be microscopic and may not show on an x-ray, when it opens, the pulp inside the tooth becomes irritated. The pulp is a soft tissue that contains the tooth’s nerves and blood vessels. If the crack irritates the pulp, the tooth may become sensitive to temperature extremes. If the pulp becomes damaged or diseased root canal treatment may be necessary to save the tooth.
