Orofacial pain is a general term covering any pain which is felt in the mouth, jaws and the face. It is a common symptom, and there are many causes. It is estimated that over 95% of cases of orofacial pain result from dental causes (i.e. toothache caused by pulpitis or a dental abscess).
After dental pain, the second most common cause of orofacial pain is temporo-mandibular joint dysfunction (TMD, pain-dysfunction syndrome). All other causes of orofacial pain are rare in comparison, although the full differential diagnosis is extensive.
