Hot and cold tooth bite pain is usually due to hidden cracks that reach deep into the pulp of the tooth, resulting in inflammation and infection of the pulp, as follows.
1. Cryptic fissure is a small crack that occurs on the surface of the crown of the tooth, which is not easy to be detected by the naked eye. When the crack progresses to a certain depth, the tooth bites at or near the crack, causing bite pain. In addition, excitation pain or spontaneous pain may also occur.
2. When the fissure reaches the pulp, bacteria will enter the pulp cavity through the fissure to infect the pulp, which will lead to the occurrence of pulpitis, and then the affected tooth will produce pain when it is stimulated by hot and cold.
There may be other reasons for hot and cold tooth bite pain, it is recommended to go to the hospital in a timely manner, with the help of the doctor to clarify the cause of the disease, and then targeted treatment.
