If you have noticed a clicking or popping sound when you open your mouth, chew, or yawn, you are not alone.
Jaw clicking is a very common experience, and for many people it is a minor inconvenience that comes and goes.
But when it is accompanied by pain, stiffness, or difficulty chewing, it may be a signal worth paying attention to.
Understanding why your jaw clicks when you chew is the first step toward finding the right approach to managing it.
What Causes Jaw Clicking?
The clicking sound you hear typically originates from the temporomandibular joint, often referred to as the TMJ. This is the joint on each side of your face that connects your lower jaw to your skull. When this joint or the soft tissue disc inside it is not moving smoothly, it can create audible sounds during jaw movement.
Several factors can contribute to jaw clicking.
Disc Displacement
Inside each temporomandibular joint is a small disc of cartilage-like tissue that acts as a cushion between the bones. When this disc moves slightly out of its normal position, it can create a clicking or popping sound as the jaw opens and closes. This is one of the most common reasons for jaw clicking and is often associated with temporomandibular disorder (TMD).
Jaw Misalignment
How to fix jaw alignment is a question that often comes up in connection with clicking, and with good reason. When the teeth and jaws do not come together in a balanced way, the jaw may need to shift or compensate with each bite, which can place strain on the joint and surrounding muscles. Over time, this can contribute to TMJ symptoms including clicking, soreness, and stiffness.
Bruxism and Clenching
Grinding your teeth at night or clenching your jaw during periods of stress are both common habits that can cause significant wear on the jaw joint and surrounding structures. Patients who grind or clench frequently are more likely to develop TMJ-related symptoms, including jaw clicking and jaw pain when opening the mouth.
Arthritis
In some cases, particularly in older adults, arthritis affecting the temporomandibular joint can cause clicking and discomfort. Osteoarthritis and rheumatoid arthritis can both affect this joint, leading to changes in its structure over time.
Stress and Muscle Tension
Emotional stress frequently manifests physically in the jaw. When people are anxious or under pressure, they often unknowingly tighten their jaw muscles, which can disrupt the smooth movement of the joint and contribute to clicking sounds and discomfort.
Why Does My Jaw Hurt When I Open My Mouth?
If you are experiencing jaw pain alongside the clicking, it suggests that the joint or surrounding muscles are under some form of stress or irritation.
Jaw pain when opening the mouth can range from a dull ache to a sharp discomfort, and it may worsen with activities like yawning, chewing tough foods, or holding the mouth open for extended periods during dental appointments.

How to Stop Jaw Clicking
The approach to managing jaw clicking depends on the underlying cause. Here are some options that are commonly recommended.
Rest the Jaw
Avoiding very hard or chewy foods can help reduce the strain on the joint during a period of active symptoms. Eating softer foods and cutting food into smaller pieces takes pressure off the jaw and may reduce clicking frequency.
Apply Heat or Cold
Applying a warm compress to the jaw area can help relax tense muscles, while cold packs can reduce inflammation. Alternating between the two is sometimes helpful, but follow the guidance of a healthcare professional for your specific situation.
Practice Jaw Exercises
Gentle stretching and strengthening exercises for the jaw can help improve range of motion and reduce muscle tension over time. A physical therapist or dentist familiar with TMD management can recommend appropriate exercises for your situation.
Night Guards
A custom-fit night guard worn during sleep can protect the joints and teeth from the effects of grinding and clenching. This is often one of the most effective interventions for patients whose jaw symptoms are driven by bruxism. More information is available on the Diamond Braces blog on how to stop grinding your teeth.
Stress Management
Since stress is a significant driver of jaw clenching and tension, finding effective ways to manage stress can have a meaningful impact on TMJ symptoms. Techniques such as mindfulness, regular exercise, and sufficient sleep can all help reduce the physical toll of stress on the jaw.
When to See a Professional
Occasional, painless jaw clicking is generally not a cause for concern. However, you should consider seeking professional evaluation if the clicking is accompanied by pain or tenderness in or around the jaw, if you have difficulty fully opening or closing your mouth, if the jaw feels like it locks or catches, or if you notice the problem getting progressively worse over time.
An orthodontist, general dentist, or orofacial pain specialist can evaluate your bite, jaw function, and symptoms to determine what is contributing to the issue and what approach is most appropriate for you.

FAQ
Why does my jaw hurt when I open my mouth?
Jaw pain when opening the mouth can result from inflammation or dysfunction in the temporomandibular joint, muscle tension from clenching or grinding, or bite misalignment. If the pain is persistent or worsening, it is worth having your bite and jaw function evaluated professionally.
Can Invisalign Fix Jaw Alignment Issues?
In some cases, bite misalignment contributes meaningfully to jaw clicking and discomfort. When that is the case, orthodontic treatment may be part of a broader management approach. Can Invisalign fix jaw alignment? In cases where the jaw symptoms are connected to how the teeth come together, aligning the teeth more effectively through braces or clear aligners may reduce the stress on the joint. However, orthodontic treatment is not a standalone cure for TMJ disorder, and it should be considered carefully in consultation with both an orthodontist and your general dentist.
