Yawning jaw dislocation needs to be reset and treated, which needs to be carried out under the operation of professional doctors, through the four methods of pulling, pressing, pushing and lifting to reset. 1. Dislocation of the jaw, i.e., dislocation of the temporomandibular joint, is often caused by yawning and eating with a wide mouth, and the patient will have difficulty in shutting up and spitting out words. In case of TMJ dislocation, you need to consult a doctor as soon as possible and have a professional doctor to perform manipulation to reset the jaw. 2. Pull the chin forward for 5 minutes, then press the chin down with fingers for 5 minutes, then push the jawbone quickly and lift it upward to reset the TMJ. Taping immobilization for more than 2 weeks is also required to limit mouth movement. If manipulation of the reset does not help much, surgery is needed. Patients with TMJ dislocation need to avoid opening their mouths too wide in their daily lives, such as laughing, to avoid reoccurrence of TMJ dislocation.
