Jaw clicking, locking and restricted opening
Understanding jaw clicking and movement changes
Inside each jaw joint is a small disc that helps the joint move smoothly.
In a clicking joint, the small disc inside the joint may sit slightly in front of the rounded end of the lower jaw when the mouth is closed. As the mouth opens, the jaw may move back underneath the disc. This change in position can produce a click or pop.
If the disc stays in front and the jaw cannot move underneath it, the joint may not open as freely. The jaw may catch, lock or feel harder to open. Pain and tightening of the surrounding muscles can also make movement more restricted.
A painless click that does not affect how the jaw moves often does not require treatment. Assessment is more important when clicking is accompanied by pain, catching, locking, reduced opening or symptoms that are becoming more frequent.
Where it shows up
Changes in movement can feel different for each person
Jaw movement changes are not always painful. Some people notice a click or pop without discomfort, while others experience pain, catching, locking or difficulty opening the mouth fully.
Common experiences include
- clicking or popping when opening, closing or chewing
- a feeling that the jaw catches, shifts or moves off-track
- difficulty opening the mouth fully
- the jaw feeling stuck or temporarily locked
- pain, pressure or discomfort during jaw movement
- needing to move the jaw a certain way to open comfortably
The way these symptoms present can vary depending on whether the main issue is joint-related, disc-related, muscle-related or influenced by clenching, guarding or loading patterns.
Symptom patterns
Understanding what different patterns may mean
Clicking or movement changes do not always mean something is worsening. In other cases, clicking, catching, locking or restricted opening may suggest that the joint, disc or muscles are under increased load.
Clicking without pain or restriction
Clicking with pain
May reflect joint irritation or increased loading of the joint structures
Intermittent catching or locking
May indicate changes in how the disc is moving during function
Restricted opening
Similar symptoms can have different meanings
The significance of clicking or changes in jaw movement depends on the overall symptom pattern.
We consider whether the symptoms are painful, whether movement is becoming restricted, whether the jaw catches or locks, and whether the pattern is stable or changing over time.
These details help determine whether the joint is functioning comfortably or whether further assessment, monitoring or treatment may be appropriate.
Whole-body connections
The jaw doesn’t work in isolation
Clicking and locking usually relate primarily to movement within the jaw joint. However, tight or protective jaw and upper-neck muscles may also affect how comfortably and freely the jaw moves.
Jaw movement may be influenced by:
- changes in how the joint disc moves;
- muscle tension or guarding;
- clenching or grinding;
- repeated or prolonged jaw use, such as chewing, talking or yawning;
- pain or restricted movement in the upper neck; and
- how well the two jaw joints and chewing muscles work together.
Where relevant, we consider these factors during your assessment, particularly when clicking or locking is accompanied by pain, muscle tightness or restricted opening.
01
Disc movement
The disc may not move smoothly with the jaw joint, which can contribute to clicking, catching or locking
02
Muscle imbalance
Tension or protective muscle activity can affect how freely the jaw opens and closes.
03
Overload from clenching
Repeated clenching or grinding can increase load on the joint, disc and surrounding muscles.
04
Changes in jaw movement
Jaw movement may become less smooth, restricted or more effortful over time.
How symptoms change
Movement patterns can vary over time
Changes may be influenced by:
- clenching or grinding
- stress or muscle tension
- prolonged talking or chewing
- sleep quality
- neck and postural factors
How we help
Care guided by your diagnosis
Clicking or movement changes do not always require treatment. When care is needed, it is based on understanding what is contributing to the change in movement.
Assessment may consider:
- disc position and joint mechanics
- muscle activity and coordination
- bite function and loading patterns
- contributing habits and whole-body factors
Because of this, people with similar symptoms may require different approaches.
Care may involve a combination of:
- monitoring and education
- jaw loading and habit modification
- orthotic support where appropriate
- muscle-focused strategies
- movement or exercise-based approaches
- addressing contributing factors such as posture or habits
Treatment depends on the severity and pattern of symptoms, and is introduced in stages where appropriate.
When to seek an assessment
Clicking is associated with pain
Jaw movement feels restricted or changes over time
The jaw locks open or closed
Difficulty eating or speaking develops
Symptoms are worsening or becoming more frequent
If jaw clicking, pain or restricted movement is affecting you, an assessment can help clarify what may be contributing

Our approach to TMJ care
Whole-body care guided by diagnosis
TMJ symptoms rarely come from the jaw alone. They can involve joint mechanics, muscle tension, bite function, posture, breathing, and sleep. At TMJ Centre Melbourne, care begins with understanding why symptoms are occurring. Treatment decisions follow diagnosis, not symptom labels. Care plans are personalised and often combine approaches, with progress reviewed and adjusted over time.
Diagnosis first
Whole-body assessment
Multidisciplinary care
Staged treatment
Evidence-Informed Care
We use recognised diagnostic frameworks and current literature to help guide assessment and treatment planning where relevant.
