Jaw joint pain: causes and help

Pain near the ear, jaw fatigue, or difficulty opening the mouth wide may be related to joint or masticatory muscle disorders. Similar symptoms can also be caused by other conditions.

What are jaw joint disorders?

The temporomandibular joint of the lower jaw is located on both sides of the face in front of the ears. Together with muscles, it allows opening of the mouth, chewing, and speaking. Disorders of the joint and masticatory muscles include several different conditions.

Pain in the jaw does not always originate from the joint itself. Sometimes dental, ear, or other facial area problems must be ruled out.

What symptoms may occur?

There may be pain in the masticatory muscles, joint area, face, or neck; opening the mouth may become more difficult, and the jaw may become stuck. Some people experience painful clicking or crackling sounds.

A joint sound alone without pain is common and usually does not mean treatment is needed. Assessment is important when pain is present or movement is impaired.

What can cause these symptoms?

Some disorders may involve trauma, muscle tension, and other factors, but in most cases, no clear single cause is identified. Clenching the teeth or frequent chewing of gum can increase muscle load.

One should not automatically assume that pain is caused by an incorrect bite or that changing tooth position is necessary to eliminate it. Individual evaluation is important when deciding on treatment.

How is the examination performed?

The doctor asks when the pain started, what aggravates it, and if there was any trauma. The masticatory muscles, jaw movement, and teeth are examined. If needed to answer a specific clinical question, imaging or other tests may be suggested.

What help can be offered?

Many cases are initially managed conservatively: temporarily choosing softer foods, reducing teeth clenching and prolonged gum chewing, discussing the use of heat or cold, and appropriate exercises. A specialist selects a specific plan.

In some cases, physical therapy or a splint may be discussed. Before treatment that irreversibly alters teeth, bite, or joint, it is worth discussing alternatives, benefits, and risks.

When to seek urgent help?

If the jaw becomes stuck, the bite changes after trauma, or pain increases and interferes with eating, contact a doctor or dentist. After severe facial trauma, severe swelling, or breathing difficulties, call emergency services at 112.
