Clicking or popping in the jaw is common, and on its own it usually isn’t a cause for concern. What matters more than the sound itself is whether it comes with pain, stiffness, or trouble opening your mouth fully. When those other symptoms show up alongside the noise, it’s a better sign that something in the joint needs attention.
The temporomandibular joint, or TMJ, sits just in front of each ear and connects your lower jaw to your skull. A small disc inside the joint helps it move smoothly. When that disc shifts slightly out of its usual position, it can create a click or pop as the jaw opens or closes. This is a mechanical event, and it doesn’t automatically mean the joint is damaged or that treatment is required.
What Causes Jaw Clicking or Popping
Jaw sounds typically come from one of a few sources:
- Disc movement within the joint. The cushioning disc inside the TMJ can shift position slightly during movement, creating a click as it moves back into place.
- Muscle tension or overuse. Clenching, teeth grinding, or chewing gum frequently can tire the muscles that control jaw movement and contribute to joint noise.
- Joint wear over time. A grating or gravelly sound, sometimes called crepitus, can develop when the surfaces inside the joint have worn down.
- General joint hypermobility. Some people simply have joints that move slightly more than average, which can produce sound without any underlying problem.
When Clicking Is Not a Concern
According to the National Institute of Dental and Craniofacial Research, sounds such as clicking or popping in the jaw joint are common, are considered normal, and don’t need treatment when there’s no pain involved. Many people go through periods of occasional jaw clicking that comes and goes without ever developing into anything more.
If your jaw clicks only occasionally, doesn’t hurt, and doesn’t limit how wide you can open your mouth, it’s reasonable to simply keep an eye on it rather than seek treatment right away.
When Clicking May Signal a TMJ Disorder
Clicking becomes more worth discussing with a dentist when it’s paired with other symptoms. The NIDCR notes that the following signs may point to a temporomandibular disorder, commonly called TMD:
- Pain in the jaw joint or the muscles used for chewing
- Pain that spreads to the face or neck
- Jaw stiffness
- Limited movement or the jaw locking open or closed
- Painful clicking, popping, or grating when opening or closing the mouth
- Ringing in the ears, hearing changes, or dizziness
- A change in how your upper and lower teeth fit together
The Cleveland Clinic notes that jaw popping can occur on one or both sides of the face and can range from mild to more noticeable, and that it’s worth mentioning to a healthcare provider even if pain hasn’t developed yet, particularly if the sound happens regularly during everyday eating or speaking.
What a Dental Evaluation Involves
There’s no single standard test for diagnosing TMJ disorders, so a dentist typically starts by asking about your symptoms, including when the clicking started, what makes it better or worse, and whether you’ve noticed jaw stiffness, headaches, or changes in your bite. From there, a physical exam usually includes checking your jaw’s range of motion, listening and feeling for joint sounds, and gently checking the surrounding muscles for tenderness.
Imaging such as an X-ray, MRI, or CT scan may be recommended in some cases, though it isn’t always necessary for milder symptoms. Because jaw and facial pain can sometimes come from other sources, a dentist may also check for dental or sinus-related causes before settling on a TMJ-related explanation.
Conservative Care Comes First
If an evaluation points to a TMJ-related cause, most dentists start with the simplest options rather than jumping to anything invasive. According to the NIDCR, TMD symptoms often improve without treatment, and initial steps commonly include eating softer foods for a while, applying heat or cold to the area, gently stretching the jaw muscles, and reducing habits like clenching, gum chewing, or nail biting. A custom night guard may also be considered if nighttime grinding or clenching appears to be contributing to the symptoms.
The NIDCR specifically cautions against treatments that permanently change the bite, teeth, or jaw joints, or that involve surgery, noting that evidence supporting many of these more invasive approaches is limited. Surgery is generally reserved for cases with significant joint damage or severe symptoms that haven’t responded to more conservative care.
Everyday Habits That Can Add Strain
A few common habits tend to place extra load on the jaw joint and muscles, and cutting back on them can sometimes ease clicking or reduce the chance of it becoming painful. Chewing gum for long stretches, biting nails or pens, resting your chin on your hand, and clenching your teeth while concentrating or under stress all ask more of the joint than everyday chewing and speaking do.
None of these habits are dangerous on their own, but reducing them can lessen the mechanical stress that contributes to clicking, and it’s often one of the first things a dentist will ask about during an evaluation. Being mindful of how often your teeth touch throughout the day, aiming to keep them slightly apart with lips closed when you’re not eating or speaking, is a simple habit that many people find helpful.
When to See a Dentist
It’s worth booking an evaluation if your jaw clicking is accompanied by pain, if your jaw locks or catches when opening or closing, if you notice your bite feels different, or if the clicking has become more frequent or noticeable over time. Clicking that shows up alongside jaw pain on one side, headaches, or ear symptoms is also worth mentioning during an exam, since these can sometimes point toward the same underlying joint issue.

Frequently Asked Questions
Is it normal for my jaw to click when I open my mouth?
Yes, occasional clicking without pain is common and is generally considered a normal finding rather than a sign of a disorder.
Should I worry if my jaw pops but doesn’t hurt?
Painless popping usually doesn’t need treatment. It’s still worth mentioning to a dentist if it happens frequently, especially during a routine check-up, so it can be monitored over time.
Can jaw clicking go away on its own?
It can. Many people notice clicking that comes and goes without any lasting change, particularly when it isn’t linked to pain or a specific habit like clenching.
What’s the difference between clicking and a jaw that locks?
Clicking is a sound during movement, while locking means the jaw temporarily gets stuck open or closed and resists movement. Locking is a stronger signal that a dentist should take a closer look.
Will a night guard stop my jaw from clicking?
A night guard may help if clenching or grinding is contributing to your symptoms, but it isn’t guaranteed to eliminate clicking on its own. A dentist can help determine whether it’s an appropriate option for your situation.
Can stress make jaw clicking worse?
Yes. Stress often shows up as jaw clenching or teeth grinding, even when you’re not aware of it happening. Reducing tension in the jaw during the day and addressing clenching habits can sometimes ease clicking that’s related to muscle strain.
If your jaw clicking comes with pain, stiffness, or a change in how your bite feels, book an appointment at Florence Dentistry for an evaluation. Our team also provides neuromuscular dentistry for patients whose jaw joint and bite issues need a more focused approach.
