Short answer: a click or pop when you open wide is common, and on its own it does not always mean a problem. It is worth an exam if the clicking comes with pain, locking, trouble opening or chewing, or headaches. A dentist can tell the difference, and many people only need reassurance and a few habit changes.
Why jaws click
Your jaw joint (the temporomandibular joint, or TMJ) has a small cushion of cartilage called a disc that sits between the jaw bone and the skull. A click or pop can happen when the disc shifts slightly as the jaw opens or closes. Many people have this for years with no pain and no limits on what they can do.
Because clicking is so common, the sound alone is not a good guide. What matters is what goes with it.
Signs worth asking about
Take these together. One alone means little, and several at once are a good reason to book an exam.
- Pain in front of the ear, in the jaw, or along the cheek when you chew or yawn.
- Locking. The jaw catches, or will not open or close fully for a moment.
- A smaller opening than before, or the jaw drifting to one side as you open.
- Trouble chewing tougher foods, or a bite that suddenly feels different.
- Morning jaw soreness or headaches around the temples.
- Ringing, fullness or an earache with no ear infection found.
A simple, gentle self-check: in front of a mirror, open slowly as wide as is comfortable. Notice whether your jaw travels straight down or drifts to one side, and whether anything catches or hurts. Do not force it. Write down what you notice, because it helps us.
What can make it worse
Clenching or grinding, often at night, is a common companion of jaw problems. Chewing gum all day, biting nails or pens, resting your chin on your hand, and long periods of stress can all keep the muscles tense. If you suspect you grind, our post on how to tell if you grind your teeth goes through the signs.
A note on a relaxed jaw
Many Eastern traditions, from yoga to mindfulness practice, pay attention to where we hold tension, and the jaw is a common place. A simple habit some people find helpful is to rest with lips together, teeth slightly apart and the tongue resting gently on the roof of the mouth, and to unclench through the day when they notice it.
It is a perspective and a habit, not a treatment. Relaxation can support comfort, but it should not replace an exam if you have pain, locking or limited movement.
What we look at in an exam
We ask about your symptoms and habits, feel the jaw muscles and joint as you open and close, measure how far you can open, and check your teeth for wear that suggests clenching. Some patients need nothing more than advice. Others may benefit from an initial consultation, where we evaluate your jaw and use imaging when needed to understand what’s causing the clicking. Based on our findings, we recommend care tailored to your needs to help address your symptoms and improve jaw function. Read more on our TMJ page.
Jaw clicking, with pain or locking?
A short exam can tell us whether it is a harmless click or something worth looking after. There is no obligation, and many patients are glad they asked.
Frequently Asked Questions
Is jaw clicking always a sign of TMJ disorder?
No. Many people have a click or pop in the jaw with no pain and no limits on movement, and it often needs no treatment. It becomes worth an exam when the clicking comes with pain, locking, a reduced opening or trouble chewing.
When should I see a dentist about jaw clicking?
Book an exam if the clicking comes with jaw or ear-area pain, if the jaw locks or catches, if you cannot open as wide as before, or if your bite suddenly feels different. Do not wait if the jaw is stuck and will not open or close.
Can clenching or grinding cause jaw clicking?
Clenching and grinding can strain the jaw muscles and joint and are often found alongside jaw symptoms. Worn teeth, morning jaw soreness and temple headaches are clues. An exam can show whether it is likely.
Will jaw clicking go away on its own?
Sometimes. Mild clicking often comes and goes, and simple steps such as softer foods for a while, avoiding wide yawns and gum chewing, and managing clenching can help. If it persists or gets painful, have it checked.
Do relaxation or breathing habits fix TMJ problems?
Relaxing the jaw and calm breathing can support comfort and are healthy habits. They have not replaced an exam for pain, locking or limited movement, and they are not a treatment for a jaw joint disorder on their own.
