Why Does the Jaw Click or Pop, and When Does It Matter?

Jaw clicking and popping are most frequently linked to the kinematics of the temporomandibular joint (TMJ), the movement of the articular disc, or masticatory muscle function. Experiencing a click, pop, grating sensation, or catching feeling when opening the mouth does not automatically indicate a severe underlying pathology.

When joint sounds are painless, do not restrict mandibular opening, and involve no jaw locking, they are generally not classified as an urgent clinical condition. However, if the sound is accompanied by pain, catching, reduced mouth opening, chewing difficulty, onset following trauma, or changes in dental occlusion, a comprehensive TMJ evaluation is indicated.

The essential clinical question is not merely “Why is my jaw clicking?” but rather: Is this sound accompanied by pain, jaw locking, or a loss of functional range of motion?

Why Does the Jaw Make a Sound?

The temporomandibular joint is a movable structure where the lower jaw connects with the skull. This joint works continuously while speaking, eating, yawning, and chewing. The disc structure, ligaments, muscles, and bone surfaces inside the joint work together to facilitate movement. When there is a disharmony in one of these structures, sounds coming from the jaw may become noticeable. In some people, the sound has been present for a long time and does not cause pain. In others, the sound is newly started, gradually increasing, or seen together with jaw locking. The clinically important distinction begins here.

Movement of the temporomandibular joint disc

The structure called the disc in the temporomandibular joint helps joint movement to be more balanced. When the position or movement of the disc changes, a “click” or “snap” sound may be heard when opening the mouth. This sound is sometimes painless; sometimes it can be accompanied by a feeling of catching, skipping, or locking during jaw movement. In disc-related jaw clicking, a person usually feels a sound at the exact same point while opening or closing their mouth. If the sound is painless and does not restrict mouth opening, it can be monitored. However, if there is pain, locking, or difficulty during opening and closing, the temporomandibular joint should be evaluated.

Teeth clenching and jaw muscle tension

The habit of teeth clenching or teeth grinding can cause overloading of the masticatory muscles. This increases the force placed on the temporomandibular joint and, over time, can lead to complaints such as jaw clicking, morning jaw fatigue, temple pain, or tenderness while chewing. Stress, clenching teeth during sleep, chewing on one side, and consuming hard foods for prolonged periods can also strain the muscles. In this case, the sound may originate not only from the joint itself but also from the unbalanced operation of the muscles controlling the joint.

Bite misalignment or missing teeth

The occlusion (bite) relationship of the teeth can affect the working order of the temporomandibular joint. Missing teeth, high dental fillings, ill-fitting prostheses, or long-term unilateral chewing can alter the load on the temporomandibular joint. This does not always directly mean temporomandibular joint disease. However, if the chewing side has changed along with jaw clicking, if the teeth do not close as they used to, or if the sound started after a new filling or prosthesis, an evaluation by a dentist is beneficial.

Trauma or sudden strain

Receiving a blow to the jaw, biting forcefully into a hard food, keeping the mouth open for long periods during lengthy dental treatments, or yawning very widely can strain the temporomandibular joint. In such situations, jaw sounds can begin suddenly. A jaw sound that starts after trauma should not be left unattended if it is accompanied by pain, limitation in mouth opening, deviation of the jaw to the side, or a change in bite. Because here, unlike a simple click, the joint, muscle, or ligament tissue may have been affected.

When Is Jaw Clicking and Popping Important?

The sound coming from the jaw does not always require treatment on its own. However, if certain symptoms are present, this sound should no longer be viewed merely as a “click.” Temporomandibular joint evaluation is especially important for sounds accompanied by pain, locking, reduction in mouth opening, or sounds that start after trauma.

If there is pain

If there is pain along with the jaw sound, this situation should be handled more carefully. Pain can be felt in the temporomandibular joint, in front of the ear, in the temple, in the cheek, or in the masticatory muscles. Pain that increases during chewing may suggest muscle and joint overloading. If the pain is gradually increasing, becoming distinctly unilateral, or affecting daily chewing comfort, monitoring only the sound may not be sufficient.

If there is jaw locking or catching

Catching of the jaw while opening, staying stuck at a certain point when opening the mouth, or sometimes locking completely is an important symptom. This condition may be related to articular disc movement or muscle spasm. It is not right for patients experiencing locking to try to force their jaw open. Forcible movements can further irritate joint and muscle tissues. In such a case, a temporomandibular joint examination should be performed.

If mouth opening has decreased

A decrease in mouth opening that could normally be opened comfortably may point to a problem related to the temporomandibular joint or masticatory muscles. A person may notice that they cannot open their mouth as much as before while yawning, eating, or brushing teeth. A decrease in mouth opening should not be neglected, especially if it is accompanied by pain or jaw sounds. Because this situation means not just a sound, but a loss of function.

If it started after trauma

If sounds started coming from the jaw after a blow, fall, accident, or sudden strain, evaluation is more important. If there is a change in bite, jaw deviation, swelling, or difficulty in chewing after trauma, an oral and maxillofacial surgery consultation may be required. At ON7 Clinic, such temporomandibular joint and surgical dental problems can be evaluated by Dr. Emre Çimen, who works in the field of oral and maxillofacial surgery.

Is It Normal for the Jaw to Make a Sound When Opening the Mouth?

Sounds coming from the jaw when opening the mouth can be seen in many people. If the sound is painless, mouth opening is normal, the jaw does not lock, and the complaint is not progressive, it is most often not evaluated as an emergency.

However, if the sound has started recently, is gradually increasing, or the jaw deviates to the side during mouth opening, an evaluation is necessary. Especially if jaw clicking turns into locking after a while, this may indicate that joint movement has deteriorated more significantly.

What is important here is not the sound itself, but what comes along with the sound. A painless and stable click is not the same thing as a painful, catching, and function-limiting click.

Does Jaw Clicking Go Away on Its Own?

Jaw clicking may decrease on its own in some individuals. Especially in complaints related to short-term muscle tension, temporary strain, or habit changes; resting the jaw, avoiding hard foods, and paying attention not to open the mouth too wide can provide relief.

However, if the sound has been continuing for a long time, is accompanied by pain, or restricts jaw movement, waiting for it to go away on its own may not be right. As some temporomandibular joint problems progress, pain, locking, and chewing difficulties can become more pronounced.

What Can Be Done at Home for Jaw Clicking?

If the sound coming from the jaw is mild and painless, the person can try to prevent the complaint from increasing by paying attention to habits that strain the temporomandibular joint. These recommendations do not replace treatment; they can only help protect the joint from unnecessary load.

It can be helpful to avoid hard and sticky foods for a while, not to chew unilaterally, to reduce chewing gum, to take care not to open the mouth too wide, and to monitor this habit if teeth clenching is noticed.

If there is night teeth clenching, morning jaw fatigue, or temple pain, a personalized splint or different supports may be required. This decision should be made after an examination. It should not be forgotten that standard over-the-counter splints may not be suitable for every patient.

How Is Jaw Clicking Diagnosed?

Diagnosis in jaw clicking begins with understanding how the patient’s complaint started and under which conditions it increases. The doctor evaluates mouth opening, jaw movements, the timing of the joint sound, masticatory muscles, dental occlusion, and missing teeth if any.

In some patients, clinical examination alone may be sufficient. However, if there is trauma, locking, a marked decrease in mouth opening, severe pain in the joint area, or suspicion of structural problems, additional imaging methods may be required.

In temporomandibular joint problems, the treatment decision is not made solely based on sound. Whether the sound is painful, whether it affects function, and how much it challenges the patient’s daily life are evaluated together.

How Is Jaw Clicking Treated?

Treatment for jaw clicking is planned according to the cause of the sound and accompanying symptoms. Not every jaw click requires surgical treatment. In many temporomandibular joint problems, the first approach is more conservative and reversible methods.

In cases related to muscle tension and teeth clenching; habit regulation, jaw exercises, soft diet recommendations, personalized splints, or physical therapy supports may come to the agenda. If there are missing teeth, bite problems, or ill-fitting prostheses, they may need to be corrected.

Surgical approaches are generally considered in selected cases where pain, locking, loss of function, or structural joint problems are more advanced. Therefore, the complaint of “sound coming from the jaw” does not directly mean surgery.

How Is Jaw Joint Clicking Evaluated at ON7 Clinic?

At ON7 Clinic, the complaint of sound coming from the temporomandibular joint is not evaluated merely as “is there a sound or not?”. How long the sound has been present, whether pain accompanies it, mouth opening, locking history, teeth clenching habits, missing teeth, and bite relationships are examined together. Cases in the field of oral and maxillofacial surgery and surgical dental problems can be evaluated by Dr. Emre Çimen. Especially if there is a jaw sound starting after trauma, limitation in mouth opening, jaw locking, or a bite change, a more detailed examination may be required in terms of the temporomandibular joint. After the evaluation, the goal is not to apply the same treatment to every patient, but to distinguish whether the sound is a monitorable condition, a functional problem of muscle-joint origin, or a presentation requiring further investigation.
