The pain in the biting muscle position of the right cheek may be related to overstrain of the biting muscle, temporomandibular joint disorder, and infection of the biting muscle gap. 1. Overstrain of biting muscle: when biting hard food or chewing repeatedly, it can make the biting muscle move excessively, which makes the body’s creatine kinase secretion too high, thus leading to localized soreness. 2. Temporomandibular joint disorder: when opening the mouth wide or chewing, due to the friction between the joints, it may be manifested as pain around the joints and popping sound, etc. There may be pain in the biting muscle position of the cheek on the right side of the face. 3. Infection of the bite muscle gap: If you suffer from wisdom teeth pericoronitis or periapical inflammation, etc., the symptom may appear due to local inflammatory stimulation. It is recommended that people with right cheek biting muscle position pain should go to regular hospitals in time to clarify the cause of the disease and carry out standardized treatment under the guidance of doctors.
