Dislocation of the jaw is usually caused by temporomandibular joint disorders, in which case the cause of the dislocation must be found in a timely manner. If it is due to a chaotic bite in the mouth, it can be corrected by means of orthodontics, so that the joints are located in the correct position, thus avoiding frequent dislocations of the jaw. If the muscles are too tense or spasmodic, local anesthesia can be considered, which can identify which muscle has a problem, and later can be combined with physical therapy to correct the temporomandibular joint disorder. After the dislocation occurs, it is important to go to the dental hospital in time, so that the doctor can carry out the reset of the temporomandibular joint, and at the same time to tie a bandage, so as to avoid the formation of recurring dislocation of the jaw joint phenomenon.
