Temporomandibular joint disorders can first be treated conservatively and in severe cases can be reset surgically. TMJ disorder is one of the most common diseases in dentistry and is characterized by pain, restricted opening, and popping or rustling sounds at the joint when opening. If one side is stressed for a long period of time, it may lead to disorders of the muscles and surrounding soft tissues on one side, resulting in TMJ disorder. TMJ disorders can also be caused by an imbalanced bite between the upper and lower teeth, malocclusion, and wisdom tooth bite disorders, which can be diagnosed with a CT scan of the temporomandibular joint. TMJ disorders can be treated conservatively, usually with hot compresses on the TMJ and topical diclofenac diethylamide ointment as prescribed by the doctor, and avoiding chewing hard foods and eating soft foods as much as possible. If conservative treatment is not effective, surgery can be performed. TMJ disorders require surgical treatment in severe cases, which mainly involves finding an incision in the preauricular region, exposing the joint cavity for treatment, and finally repairing the joint disk. Patients with temporomandibular joint disorders need to go to a regular hospital and use the appropriate treatment plan under the advice of a doctor.
