The temporo-mandibular joint (TMJ) connects your mandible (jaw bone) to the temporal bone of your skull i.e. your jaw joint. We have two TMJs and they are located in close proximity to each ear. Between your mandible and your skull we have a meniscus (cartilagenous disc) acting as a cushion to prevent bone on bone contact, facilitate joint movement and absorb the forces endured during eating, drinking, yawning etc. Lots of muscles are responsible for producing movement of the TMJs and are activated most of the day during yawning, speaking, feeding and breathing. Thus, the TMJ is one of the most used joints in the body and can be predisposed to injury/disorder.

‘Temporomandibular disorders’ (TMD) is a collective term embracing a number of clinical problems that involve the muscles of mastication (feeding), the TMJ and associated structures, or both (Jeffrey Okeson, 1996).

It is estimated that approximately 550,000 people in Ireland suffer from TMD making this condition a significant public health problem. In fact it is the second most common musculoskeletal condition causing pain and disability.

Signs & Symptoms of TMD
TMJ related pain can be varied, diffuse and debilitating. Symptoms can include:

  1. Pain and tenderness on palpation in the muscles of mastication,or of the joint itself.

  2. Pain when chewing, clenching, or yawning

  3. Facial pain or headache that is often worse upon waking

  4. Limited range of movement of the jaw

  5. Jaw clicking, popping, graunching, locking and/or stiffness in the joint

    treatment/dental restoration

  5. Arthritic conditions

  6. Generalised Hypermobility

  7. Prolonged poor posture
