If the jaw is dislocated and reset, you should hold your chin with your hands and send it to the hospital immediately, which will be solved by a professional doctor in the hospital. The most common method is this: we ask the assistant to hold the patient's head, the doctor stands in front of the patient, two thumbs are wrapped with gauze and pressed against the lower molar, and four fingers on both sides are pressed against the outer lower part of the mandible, then both hands are forced forward and downward to depress the mandibular angle, and then pushed up and down.
