Temporomandibular joint disorder
Temporomandibular joint disorder refers to pain or discomfort affecting the joint that connects the jaw to the skull, as well as the muscles that support jaw movement.
This disorder is typically classified into three categories:
- Muscular pain and functional issues
- Internal joint dysfunction
- Degenerative changes within the joint
Pain is commonly described as a dull ache that may extend into the face or neck and can be accompanied by clicking, locking or popping of the jaw. Joint movement may also be restricted, sometimes limiting how far the mouth can open.
Pain in the area can be caused by a number of reasons. Issues with the joint itself can often causing locking or clicking that is associated with pain.
In some individuals, a hypermobile jaw may be associated with pain, though TMJ disorder is often related to trauma, habitual teeth grinding and increased stress levels.
