Jaw pain and clicking: when to think about a TMD

Temporomandibular disorders (TMD) do not correspond to a single disease. The term brings together more than thirty conditions that can affect the temporomandibular joint, the muscles involved in chewing and, in some cases, produce associated headaches.

What symptoms may suggest a TMD?

The most common symptom is pain in the joint or chewing muscles. Stiffness, limitation in opening the mouth, blockages, and pain extending to the face or neck may also occur.

• Jaw pain when chewing, yawning or talking.
• Clicking accompanied by pain.
• Blockage or difficulty opening and closing the mouth.
• Recurring facial or headache pain.
• Recent changes in the way teeth fit together.

An isolated joint noise, without pain or limitation, is common and does not necessarily require treatment. Evaluation becomes important when the symptom is painful, persistent, or interferes with daily activities.

How is the diagnosis made?

There is no single test that confirms all TMD. The evaluation begins with a detailed history: where it hurts, how long it lasts, what activities trigger it, and whether there are other pains or sleep problems. The exam checks head, neck, face, joint and jaw movements.

Imaging, such as an x-ray, MRI, or CT scan, is ordered only when the history and examination indicate that it may provide relevant information.

Treatment usually begins conservatively

Many paintings improve with simple and reversible measures. Depending on the diagnosis, the plan may include education, reducing overuse habits, exercises, physical therapy, pain management, or a splint that does not permanently change the bite.

Irreversible or surgical procedures are not the first option for most people. The recommendation must be adapted to the type of TMD and the evolution of each patient.
