Why does my jaw joint click?

A clicking jaw joint, often associated with Temporomandibular Joint Disorders (TMD), can be due to several anatomical and functional issues within the jaw joint and surrounding muscles.

Here's what happens anatomically, particularly focusing on the temporomandibular joint (TMJ) and the masseter jaw muscle:

The Temporomandibular Joint (TMJ):

1. Anatomy: The TMJ connects the lower jaw (mandible) to the skull (temporal bone) in front of the ear. It's a complex joint that allows movement in multiple directions: up and down, side to side, and forward and back.

2. Disc Displacement: Inside the joint, there's a soft, cartilaginous disc that acts as a cushion and allows smooth movement of the jaw. Clicking often occurs when this disc is displaced or moves out of its normal position, usually moving ahead of the condyle (the rounded end of the jaw bone) and then snapping back into place when the mouth is opened or closed.

The Masseter Muscle:

1. Function: The masseter muscle is one of the primary muscles controlling jaw movement, particularly in chewing. It's a strong muscle that connects the lower jaw to the cheekbone.

2. Impact on TMJ: When the masseter muscle is tight or overactive, it can contribute to abnormal jaw mechanics. This tension can put extra pressure on the TMJ, exacerbating issues like disc displacement. In some cases, the muscle itself may be part of the problem, contributing to misalignment or dysfunction in the jaw joint.

3. Feedback Loop: The dysfunction in the TMJ can cause pain or discomfort, leading to further tightening or overuse of the masseter muscle, creating a feedback loop that exacerbates the problem.

In addition to the mechanical aspect, factors like stress, teeth grinding (bruxism), or trauma can also contribute to TMJ disorders and the associated clicking sound. Treatment often involves addressing the root cause, which may include relaxation techniques, physical therapy, dental interventions, or, in severe cases, surgical procedures. It's important to consult with a healthcare professional for a proper diagnosis and treatment plan.
