Jaw Locking

An injury to the jaw or temporomandibular joint can be involved, although symptoms often begin without an obvious cause. Genes, psychological and life stressors, and pain perception may influence how symptoms begin or persist.

Give the jaw rest and choose soft foods. A warm compress over a painful area and passive stretching are conservative measures used for TMD symptoms, which often improve without treatment.

The assessment starts with the location and timing of pain, what worsens or eases it, whether it spreads, and any other pain conditions. The head, neck, face, and jaw are examined; X-ray, MRI, or CT may be suggested.

Conservative treatment comes first. Education, jaw rest, a soft diet, warm compresses, stretching, improved sleep, stress management, and treatment of parafunctional habits can reduce symptoms.

Better sleep hygiene, lower stress, and changes to clenching or other parafunctional habits may improve symptoms. Permanent changes to the jaw joint, including surgery or implants, carry risks that need careful consideration.

TMD symptoms can include jaw or chewing-muscle pain, pain into the face or neck, stiffness, painful joint sounds, ringing in the ears, hearing loss, dizziness, and a changed fit between the teeth.

Restricted movement or locking alongside pain is a reason to arrange dental assessment. A painless jaw sound alone is common and is considered normal in many people.
