When you bite just right on that one tooth, you get a shooting pain. What is going on with the intermittent biting pain? If you ignore it, will it get better and just go away?
The pain on biting is called "cracked tooth syndrome." It is caused by a micro-fracture that is getting deeper every time you bite. The pain is your nerve letting you know the fracture is getting near the center of the tooth where the main nerve lives. That area is called the pulp of your tooth. Treatment is best earlier than later. Consequences of a cracked tooth are possible need for a root canal or an extraction. A crown often solves the problem if treated early in the symptoms.
