Facial pain commonly results from temporomandibular joint (TMJ) disorder. Many practitioners refer to TMJ disorder, or syndrome, as a single disorder but there are various sub-diagnoses (e.g. myofascial pain, temporomandibular joint inflammation). The disorder is common and most often occurs in people aged between 20 and 40 years (NICE 2009). Around 33% of the population has at least one temperomandibular symptom and 3.6% to 7% of the population has TMJ disorder with sufficient severity to cause them to seek treatment (Wright 2009).

TMJ disorder is an umbrella term covering acute or chronic pain, especially in the muscles of mastication, or inflammation of the temporomandibular joint (Zakrzewska 2007). The temporomandibular joint is susceptible to many of the conditions that affect other joints in the body, including ankylosis, arthritis, trauma, dislocations, developmental anomalies, neoplasia and reactive lesions. Symptoms usually involve more than one of the numerous TMJ components: muscles, nerves, tendons, ligaments, bones, connective tissue, and the teeth. Symptoms can include difficulty in biting or chewing, jaw pain or tenderness of the jaw, clicking, popping, or grating sound when opening or closing the mouth, reduced ability to open or close the mouth, a dull, aching pain in the face, dizziness, headache or migraine (particularly in the morning), neck and shoulder pain, blinking, ear pain, hearing loss and tinnitus.

Treatment of a patient with chronic facial pain includes analgesics, NSAIDs, an occlusal splint (bite guard), cognitive behavioural therapy, physiotherapy and surgery (Al-Jundi 2008).
