Key points
- TMJ disease usually develops gradually, moving through distinct stages from early disc displacement to joint arthritis.
- Each stage narrows the window for conservative treatment. The earlier the intervention, the more options are available.
- Closed lock – a sudden inability to open the mouth fully – is a medical event that needs prompt attention.
Most people who seek help for TMJ disorder have been managing symptoms for months, sometimes years. It often starts as a clicking jaw or earache without an obvious cause. Knowing the stages helps you understand what’s happening in the small but significant temporomandibular joint (TMJ) and why you should act now, rather than wait.
A clicking jaw: warning sign or nothing to worry about?
The click comes from a small disc inside the TMJ slipping out of position. In a healthy joint, this disc sits directly over the condyle (the rounded head of the lower jaw bone), absorbing load and keeping movement smooth. When the disc shifts forward, the condyle catches on it each time the jaw opens, producing that familiar, unsettling click, then catches it again on closing.
A clicking jaw is relatively common and, on its own, is not always a cause for concern. However, clicking accompanied by tenderness, stiffness, facial pain, or difficulty opening your mouth may signal that the joint is under stress and that the disc displacement is beginning to affect the surrounding tissues.
When the click becomes a clunk
A displaced disc that isn’t managed doesn’t settle back into position on its own but instead undergoes significant structural deformity. Repeated loading and movement force the disc to fold and compress on itself.
The sound often changes, with the soft click becoming a louder clunk. Your jaw may also feel stiff in the mornings or after long meals.
If this is happening to you, it’s high time someone examined your jaw! The window for conservative treatment is still open, but it is beginning to narrow.

A jaw that won’t open
Closed lock happens when the deformed disc folds so completely that it physically blocks the jaw from moving forward. You find you can’t open your mouth beyond about 30mm. Forcing it causes significant pain.
Closed lock is a TMJ condition that should be assessed promptly. Early assessment by a practitioner experienced in TMJ management can help determine the most appropriate treatment approach, which may include non-surgical care depending on the individual case.
TMJ Clinics’ multidisciplinary team of dentists and physiotherapists have all completed additional training in TMJ care following our load-reduction protocol. Treatment may include manual therapy or dry needling from our physiotherapists or a customised TMJ splint designed by our dentists.
Pain in the ear, temple and neck
As the disc deteriorates, the tissue behind the joint (retrodiscal tissue) becomes exposed to load it was not intended to bear. This tissue is dense with nerves and blood vessels. Pressure on it causes pain that radiates outward to the ears, temples and neck. By this stage, many patients do seek help but are investigated for ear infections or sinus problems when the real issue is their jaw.
If you’ve been told your ear is fine but have persistent pain, your jaw joint should be assessed.
TMJ arthritis: When the joint begins to break down
Without adequate management, the joint’s bony surfaces begin to erode and remodel. This is TMJ arthritis, a chronic, degenerative condition that is painful, limits function and is significantly more difficult to treat than earlier-stage disease.
Everything we do at TMJ Clinics is oriented towards preventing progression to this stage.

Frequently asked questions
Is jaw clicking always a sign of TMJ disease?
Not necessarily. Painless clicking without other symptoms is common and doesn’t always indicate a problem that needs treatment. Clicking accompanied by pain, stiffness, or limited jaw movement is a reason to seek an assessment.
Can TMJ disease get better on its own?
For some people with mild, early-stage symptoms, conservative self-care, such as reducing jaw loading and avoiding wide mouth opening, can help manage discomfort.
But a displaced disc doesn’t correct itself without treatment. Early assessment establishes whether active management is needed and prevents the condition from progressing.
What does a TMJ assessment involve?
A TMJ-trained dentist will examine your jaw joint, assess your range of movement, review your symptoms and history and possibly order imaging studies.
From there, we can recommend the most appropriate treatments for your stage of TMJ disorder.
At what stage should I see someone about my jaw?
As soon as the clicking is accompanied by pain, stiffness, or limited opening. Early-stage TMJ disease responds well to conservative treatment. Waiting until symptoms are more severe significantly narrows the options.
