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.

Joint Problems Spotlight

A dislocated jaw is painful and may make it impossible to close your mouth. You may notice that your teeth do not align normally or that your lower jaw seems to be further forward than usual.

A dislocated jaw can result in bleeding or difficulty breathing and must be treated in an emergency setting. It is important to limit the movement of your jaw as much as possible until you can reach your health care provider.

Seek immediate medical care (call 911) for serious symptoms, such as difficulty breathing or profuse bleeding in or around the mouth and jaw.
