Pain Management: Facial Pain
(Trigeminal Neuralgia)

Pain originating in the face, or elsewhere, may be caused by an injury, an infection in a structure of the face, a nerve disorder, or it may occur for no known reason.

Some common causes of facial pain include:

• Abscessed tooth (a condition in which a tooth is surrounded by inflammation and pus)
• Sinus infection
• Sinusitis (inflammation of the sinuses)
• Injury to the face
• TMJ disorders (TMJ stands for temporomandibular joint, or the jaw joint)
• Trigeminal neuralgia (described below)
