Pain in the bite joint is mainly caused by eating hard things for a long time, or frequent misalignment of the bite and large open mouth, or abnormal bite relationship after dental treatment, such as wearing dentures or wisdom teeth extraction, which leads to joint dysfunction and causes ear pain. For treatment, it is necessary to treat the relevant oral diseases and correct the occlusal relationship. You need to eat a light diet, eat thin and soft food, not hard food, and especially restrict wide open mouth and misaligned bite. The painful area can be warmed up with hot towels twice a day for half an hour each time, and the more obvious pain can be relieved by taking oral ibuprofen capsules.
