What is a dislocated jaw?

The jawbone, known as the mandible, fits into a joint on each side of the head (temporomandibular joints or TMJs) and becomes dislocated when the bone slides out of these joints. A dislocated jaw may be caused by forceful yawning or by an impact or force, such as being punched in the face or being in a car accident. Other activities that can lead to a dislocated jaw include laughing, vomiting, singing, eating, and even dental treatment.
