A clicking or popping sound in your jaw when you open your mouth is common and, on its own without pain, is usually not something to worry about. The click typically comes from the small cushioning disc inside the jaw joint moving slightly out of its normal position and then back again as you open and close. It becomes a genuine concern when it is joined by pain, a jaw that catches or locks, or a noticeable change in how far you can open your mouth.
Key takeaways
- Jaw clicking without pain is common and generally does not need treatment.
- The most useful question is not "does my jaw click" but "does it click and hurt, catch, or limit movement".
- Common causes include a shifted jaw joint disc, muscle tension, teeth grinding or clenching, and joint wear over time.
- Simple self-care, including a softer diet and stress management, resolves many mild cases.
- Persistent pain, locking, or a jaw that will not fully open or close needs a professional assessment.
The one question that matters: does it hurt?
Isolated jaw clicking, with no pain, no locking, and no restriction in how far you can open your mouth, is extremely common and is generally considered a normal variant rather than a disorder needing treatment. The distinction that actually matters clinically is whether the click is accompanied by pain, difficulty chewing, a jaw that catches or locks, or a visible shift in your bite. If any of those are present alongside the click, it is worth having assessed. If the click is truly silent in every other sense, most guidance is to monitor rather than treat.
What causes the clicking sound
The jaw joint, or temporomandibular joint, has a small disc of cartilage that sits between the jawbone and the skull, cushioning movement as you open and close your mouth. In many people, this disc sits slightly out of its ideal position. As the jaw opens, the disc can slip back into place with an audible click, then slip out again as the jaw closes, sometimes producing a second click. Muscle tension from stress or habitual clenching, teeth grinding, and gradual wear of the joint surfaces over the years can all contribute to or worsen this pattern.
When clicking is not usually a concern
| What you notice | Usually not concerning | Worth a check |
|---|---|---|
| Sound when opening or closing | Click with no pain, occurring consistently in the same way | New click that started suddenly, or one that has become louder or more frequent |
| Jaw movement | Full, smooth opening and closing despite the click | Jaw that catches, locks briefly, or deviates noticeably to one side |
| Pain | None, or very mild and occasional | Pain in the joint, ear, temple, or jaw muscles, especially on chewing |
| Bite | Feels the same as always | Teeth suddenly meeting differently, or a feeling the bite has changed |
| Other symptoms | None | Frequent headaches, ear fullness, or jaw fatigue with chewing |
What you can try at home for mild symptoms
- Stick to softer foods for a few days if the joint feels irritated, avoiding wide bites like whole apples or thick sandwiches.
- Avoid chewing gum, which places repetitive, prolonged strain on the joint.
- Notice and reduce clenching during the day, particularly during concentration or stress, since daytime clenching is a common and often overlooked contributor.
- Apply a warm compress to the jaw muscles if they feel tight or sore.
- Practise relaxing your jaw with your teeth apart and lips gently closed as a resting position, rather than teeth touching.
When a night guard or other treatment is considered
If clenching or grinding, particularly overnight, is identified as a contributing factor, a custom-fitted night guard is often recommended to reduce the load on the joint and the muscles around it while you sleep, and knowing how to look after a night guard helps it last. For more persistent or painful cases, treatment can range from physiotherapy-style jaw exercises through to a referral for further assessment where the joint itself needs closer investigation. Most cases of jaw clicking, even when treatment is recommended, are managed conservatively rather than surgically, and surgery is reserved for a small minority of more complex or unresponsive cases.
Could it be linked to teeth grinding?
Yes, frequently. Grinding and clenching place repeated, often unconscious, strain on the same joint and muscles involved in jaw clicking, and the two commonly occur together. If you wake with a sore jaw, notice flattened or worn tooth surfaces, or a partner has mentioned you grind at night, it is worth mentioning alongside any jaw clicking at your next dental visit, since addressing the grinding often improves the joint symptoms as well.
Frequently asked questions
Is jaw clicking a sign of TMJ disorder?
Clicking alone, without pain or restricted movement, is common and not necessarily a disorder. It becomes more likely to represent a temporomandibular disorder when pain, locking, or reduced movement are also present.
Can jaw clicking go away on its own?
For many people, mild clicking persists at a stable, harmless level for years without ever needing treatment. Simple habit changes, such as reducing clenching and gum chewing, can also reduce or resolve it in some cases.
Should I see a dentist just for jaw clicking with no pain?
It is not usually urgent, but mentioning it at a routine check-up is reasonable so it can be monitored and compared against future visits if symptoms change.
Can stress cause jaw clicking?
Yes. Stress-related clenching and muscle tension are common contributors to both jaw clicking and jaw pain, and stress management can meaningfully reduce symptoms for some people.
Will a night guard stop the clicking?
A night guard mainly protects against the effects of grinding and clenching and can reduce associated muscle tension, which sometimes reduces clicking, though it is not guaranteed to eliminate the sound itself.
When does jaw clicking need urgent attention?
If your jaw suddenly locks open or closed and will not move normally, or if clicking starts abruptly after an injury to the face or jaw, seek prompt assessment rather than waiting.
Booking with Lumi Dental
If jaw clicking is joined by pain, locking, or a bite that feels different, an assessment can help identify what is driving it and whether a night guard or other treatment would help. See our current offers or learn more on our general dentistry page.
