Jaw clicking usually happens when the small disc inside the jaw joint slips out of place and pops back as you open or close your mouth. A painless click is often harmless, but clicking with pain, locking, headaches or limited opening can point to a TMJ disorder. At Kinard Family Dental in Helotes, TX, Dr. Sarah Kinard diagnoses and treats jaw problems through TMJ/TMD treatment and explains how they connect to airway dentistry.
What Is Happening When Your Jaw Clicks?
Your jaw joint, the temporomandibular joint, sits just in front of each ear. Between the rounded end of the jawbone and the skull is a small disc of cartilage that cushions movement. When everything works smoothly, the disc moves with the jaw silently.
If the disc sits slightly out of position, the jaw has to slide over its edge as you open, which produces a click or pop. Often the disc slips back into place as the jaw closes, which can cause a second, softer click. Clicking can also come from tight or unbalanced jaw muscles, or from surfaces in the joint rubbing unevenly.
Is Jaw Clicking Normal?
Jaw clicking is common, and a click without pain or other symptoms is often not a cause for concern. Many people have a painless click for years that never changes. It is still worth mentioning at your next dental visit, so it can be recorded and monitored over time.
What matters is whether the click comes with other signs, and whether it is changing.
When Is Jaw Clicking a Sign of TMJ Disorder?
- Pain in the jaw, face, temples or in front of the ear
- A jaw that catches, locks open or locks closed
- Difficulty opening wide, or a jaw that shifts to one side as it opens
- Headaches, especially in the morning
- A grating or crunching sound rather than a single click
- A bite that suddenly feels different
Any of these alongside clicking is a reason to have your jaw evaluated. Our article on TMJ and chronic migraines explains how jaw problems and headaches are often linked.
Does Jaw Clicking Get Worse Over Time?
Not always. Many painless clicks stay the same for years. In some people, though, the disc gradually stops slipping back into place. The click may disappear, but the jaw starts catching or cannot open as wide as before. That change, sometimes called a closed lock, is a sign the joint needs attention.
Watch for clicking that becomes louder or more frequent, new pain, a jaw that catches before it opens fully or a feeling that your bite has shifted. These changes are much easier to treat early than after they have been present for months.
What Causes Jaw Clicking and Popping?
- Disc displacement: the cartilage disc sits forward of its normal position.
- Clenching and grinding: constant pressure strains the joint and muscles, often at night.
- Bite problems: teeth that do not meet evenly can load one side of the jaw more than the other.
- Injury: a blow to the jaw or a hard fall can disturb the joint.
- Joint changes: arthritis and wear can make joint surfaces rough.
- Habits: chewing gum constantly, biting nails or resting the chin on a hand.
Can Sleep and Breathing Affect Jaw Clicking?
They often do. When the airway narrows during sleep, many people clench or push the jaw forward to keep breathing, which strains the joints for hours each night. Morning jaw soreness, worn teeth and a clicking joint can all be signs of this pattern. Our adult airway sleep dentistry page explains how breathing problems during sleep are evaluated.
What Can You Do at Home for a Clicking Jaw?
- Choose softer foods for a while and cut food into smaller pieces.
- Avoid chewing gum, chewy candy and biting into large items like whole apples.
- Support your chin when you yawn to avoid opening too wide.
- Apply warm compresses to tight jaw muscles.
- Notice daytime clenching and rest your jaw with the teeth slightly apart and lips together.
Home care helps mild symptoms, but it does not correct a displaced disc or a bite problem. If pain or locking continues for more than a week or two, an evaluation is the next step.
Is Jaw Clicking the Same as TMJ Disorder?
Not exactly. Jaw clicking is a sound the joint makes. TMJ disorder, often called TMD, describes problems with the joint or the muscles around it that cause pain, limited movement or other symptoms. Clicking is one possible sign of TMD, but many people click without having a disorder, and many people with TMD never click.
That is why the evaluation looks at how your jaw moves and feels, not just at the noise it makes.
When Should You Get Help Quickly?
Contact a dentist promptly if your jaw locks open or closed, if your bite suddenly changes after an injury, or if you cannot open your mouth enough to eat. Swelling, fever or severe pain in the jaw joint should be checked by a physician or dentist the same day.
Can Children Have Jaw Clicking?
Yes. Children and teenagers can develop jaw clicking, often while the jaw is growing and the bite is changing. A painless click may settle as growth continues, but clicking with pain, headaches, teeth grinding or mouth breathing is worth evaluating. In children, jaw and airway development are closely linked, which is why our Myobrace for kids and pediatric airway care often address both together.
How Is Jaw Clicking Diagnosed and Treated?
Diagnosis starts with a careful exam of how your jaw opens, closes and moves side to side, and which muscles are tender. At our Helotes practice, CBCT imaging gives a three-dimensional view of the joints, and a digital scan captures your bite precisely.
Treatment depends on the cause. A custom oral orthotic can reduce load on the joint and protect the teeth from grinding. Bite correction, myofunctional exercises and, for some patients, Botox to relax overactive jaw muscles may be part of the plan. When the airway plays a role, treating it can ease the strain on the jaw. Our TMJ/TMD treatment page describes each option.

Schedule NowFrequently Asked Questions
Should I worry if my jaw clicks but does not hurt?
A painless click is often harmless. Mention it at your next dental visit so it can be monitored, and have it evaluated if pain, locking or limited opening develops.
Can jaw clicking go away on its own?
Sometimes, especially if it is caused by temporary muscle tension or a short period of clenching. Clicking caused by a displaced disc or bite problem often continues until the cause is treated.
Why does my jaw click when I chew?
Chewing moves the jaw repeatedly under load, so a disc that sits slightly out of place may click with each bite. Clenching, bite imbalance and tight muscles can also cause clicking while eating.
Is jaw popping a sign of TMJ?
It can be. Jaw popping with pain, headaches, locking or difficulty opening is a common sign of a TMJ disorder. Popping alone, without other symptoms, is often not serious.
Can stress make my jaw click more?
Yes. Stress often leads to clenching and grinding, which tightens the jaw muscles and strains the joint, making clicking and soreness more noticeable.
What happens if my jaw locks?
If your jaw locks open or closed, contact a dentist promptly. Do not force it. A locked jaw often needs professional treatment to restore normal movement.
Can a night guard help a clicking jaw?
A custom orthotic can reduce pressure on the joint and protect the teeth from grinding. Over-the-counter guards may not fit well and can sometimes make symptoms worse.
Does insurance cover TMJ treatment?
Coverage varies. Some dental or medical plans contribute to TMJ evaluation and treatment. Our team can help you review your benefits.
