What is the most common cause of tooth pain? Generally the most common reason for tooth pain can be summed up in one dreaded word a cavity. Granted some of us are more cavity prone than others but if we are not going to the dentist every six months the chances of having a cavity or other pains increase. What are some other reasons for tooth pain? Grinding our teeth due to increased amounts of stress that each of us have in our life could be another factor.
