What It Is

Inside the joint, a small disc rides between the jaw and the skull — when its movement goes a little off-track, that's often the click you hear.

The temporomandibular joint (TMJ) works like a sliding hinge that connects the skull to the jawbone. The TMJ is basically the jaw joint. Problems with it are often called temporomandibular disorders (TMD) (NIDCR, 2026). These disorders can cause pain in the muscles controlling jaw movement and in the jaw joint itself. The cause is often hard to determine; a mix of genes, life stresses and how a person experiences pain may play a part (NIDCR, 2026). Some people with jaw pain also grind their teeth or clench down when sleeping. However, many people habitually clench their teeth and never develop this disorder.

TMD is not usually serious and generally gets better on its own (NHS, 2023). In most cases, simple self-care and non-surgical treatments are all that is needed (NIDCR, 2026).

What Causes TMJ Pain?

  • Teeth grinding, often at night (NHS, 2023)
  • Wear and tear (osteoarthritis) of the jaw joint. Yes, the TMJ can suffer with osteoarthritis like many other joints (NHS, 2023)
  • Stress, causing repeated jaw clenching (NHS, 2023)
  • Trauma, such as a blow to the head or face (NHS, 2023)
  • Repetitive stress on the jaw, such as habits like gum chewing or nail biting (NIDCR, 2026)

Research does not support the idea that a bad bite or braces cause TMD (NIDCR, 2026).

Temporomandibular Joint Disorder (TMJ) Anatomy

The TMJ is the jaw joint, and you can feel it by placing your fingers just in front of your ears and opening and shutting your mouth (NIDCR, 2026). You have one on each side. The temporomandibular joint allows the complex movements required for eating, yawning, talking and swallowing.

There is a disc within the joint, and this acts similar to a disc in your spine – to provide cushioning and protection to the joint, and allow movement.

When the joint becomes painful, it can limit your lifestyle. Understanding what you are dealing with can help you receive the appropriate treatment.

I Get a Click in My Jaw – is This Normal?

Yes, clicking or popping in the jaw without pain is common, is considered normal, and does not need treatment (NIDCR, 2026). Most people do not notice it until they get pain. If your click is painless, the best thing you can do is try not to deliberately click your jaw and forget about it. If the click is painful, get it checked, as painful clicking can be a sign of TMD (NIDCR, 2026). Often, once you have pain, you become "aware" of a click which may have been present all along.

I Saw My Dentist, but They cannot Help, What Should I do?

Dentists are teeth experts, but not all of them focus on jaw problems. You could seek a dentist or specialist with expertise in jaw pain (an orofacial pain specialist) (NIDCR, 2026). Your family doctor or nurse practitioner may also suggest seeing a physiotherapist for advice about jaw exercises and massage, or a psychologist if stress and anxiety are making the pain worse (NHS, 2023). I can help with jaw exercises and massage too (see the My Approach tab).
