The temporomandibular joint connects the lower jaw to the temporal bone of the skull and is responsible for bringing the lower and upper jaws together. It is one of the most frequently used joints in the body. Depending on the underlying cause, jaw pain can occur suddenly or build up over time.
Dental problems, including infections, can cause facial pain and swelling in and around the jaw area. Jaw pain may be caused by a temporomandibular (TM) disorder. This condition can cause pain in the TM joint (located in front of the ear), in the ear, or above the ear.
