what to do when you have a locked jaw
If your jaw is locked open or closed, go to a hospital's emergency department. The open locked jaw is treated by sedating you to a comfortable level. Then the mandible (upper jaw) is held with the thumbs while the lower jaw is pushed downward, forward, and backward. This maneuver is usually done by the Emergency Department physician or an ear, nose, and throat (ENT) specialist. The closed locked jaw is also treated by sedating you until you are completely relaxed.
