Symptoms and Signs of Broken Jaw Symptoms, Treatments, and Recovery Time

Doctor's Notes on Broken Jaw Symptoms, Treatments, and Recovery Time

A broken jaw is a fracture or break of the jaw bone (mandible). This is a common type of facial injury. A broken jaw is most often caused by trauma in the form of a direct blow to the jawbone, occurring as a result of a face-first fall, automobile accident, sports injury, or assault.

Jaw pain is the most common symptom of a broken jaw. The pain of a broken jaw may be severe. Other associated symptoms and signs can include the sensation that the teeth are not aligned or do not fit together correctly (malocclusion), swelling of the jaw, problems with speaking or chewing, numbness of the lower lip, inability to close the mouth, and bleeding or bruising.
