TMJ Disorders: Jaw Clicking, Locking and Pain

The temporomandibular joints—commonly called the TMJs—connect your lower jaw to your skull. You use them constantly when you speak, chew, yawn, and swallow. When these joints or the surrounding muscles are irritated, symptoms can range from occasional clicking to persistent pain or a jaw that locks.

TMJ symptoms can be frustrating, but surgery is rarely the first step. My approach begins with a careful diagnosis and a focus on the simplest effective treatment for your symptoms.

Common signs of a TMJ disorder

TMJ disorders can feel different from one patient to another. You may notice:

• Pain in front of the ear or along the jaw
• Clicking, popping, or grinding sounds
• Difficulty opening the mouth fully
• A jaw that catches or locks open or closed
• Pain while chewing or speaking
• Muscle tenderness in the face, temple, neck, or jaw
• Headaches that seem connected to jaw tension
• A bite that suddenly feels different

A clicking jaw is not always a problem. If it is painless, does not limit movement, and does not interfere with daily life, it may not need treatment. Pain, locking, restricted movement, or a change in bite deserves assessment.

What can cause TMJ symptoms?

TMJ disorders often have more than one contributing factor. These may include clenching or grinding, muscle tension, joint inflammation, arthritis, prior injury, stress, bite changes, or disc displacement within the joint.

It is important not to assume that every jaw symptom comes from the TMJ. Tooth infection, sinus problems, nerve pain, and other medical conditions can produce similar discomfort. A proper assessment helps identify the likely source.

How is TMJ disorder diagnosed?

At your appointment, I ask about your symptoms, medical history, sleep habits, stress, previous injuries, and any dental treatment you have had. I examine the jaw joints, muscles, bite, and range of movement.

Depending on your symptoms, imaging such as X-rays, CT scans, or MRI may be appropriate. The aim is to understand whether the problem is mainly muscular, joint-related, dental, or something else.

Treatment usually starts conservatively

For many patients, TMJ symptoms improve without surgery. Treatment may include:

• A short period of softer foods to reduce strain on the joint
• Anti-inflammatory medication or other medication when appropriate
• Heat or cold therapy
• Gentle jaw exercises or physiotherapy
• A night guard or stabilization appliance when clenching or grinding is a factor
• Strategies to reduce daytime clenching and muscle tension
• Referral to a dentist, physiotherapist, pain specialist, or other provider when needed

Surgical treatment is considered only in selected cases, such as significant joint disease, persistent locking, structural problems, or symptoms that have not responded to appropriate non-surgical care.

When should you seek urgent assessment?

Seek prompt care if you have severe swelling, fever, trauma, sudden inability to close or open your mouth, significant worsening pain, or symptoms that may indicate infection. These problems may require a different type of treatment than a routine TMJ disorder.
