The Temporomandibular Joint (TMJ) is the hinge-like structure that connects the jaw to the skull. It is unique in being a bilateral joint made of multiple structures that move together.
Health conditions stemming from it, are referred to as Temporomandibular Joint Disorders (TMD). These disorders are often incorrectly referred to as TMJ, after the joint name rather than the pathology.
Symptoms of TMD include a wide range of physical issues not limited to the following:
- Clicking or popping during jaw movements
- Tiredness or soreness of the jaw
- Wearing down of tear associated with excessive TMJ movement
- Facial swelling
- Jaws that seem to be stuck or locked when opening, though only temporarily
In some cases, medical equipment such as mouth guards may be recommended in addressing TMD. These devices can help mitigate the damaging effects to the teeth, gums, and tongue associated with TMD.
