Why Does My Jaw Click or Pop When I Open My Mouth?

Have you ever opened your mouth to yawn, take a bite of food, or brush your teeth and noticed a clicking or popping sound near your jaw? Maybe it happens occasionally, or perhaps you’ve started noticing it every time you chew or speak.

While jaw clicking can be surprising, it’s actually fairly common. In many cases, occasional clicking or popping without pain isn’t a cause for concern. However, when these sounds are accompanied by discomfort, stiffness, or difficulty moving your jaw, they may indicate a problem with your temporomandibular joint.

At Glacier Creek Dental, we believe understanding your symptoms is an important part of maintaining a healthy, comfortable smile. Here’s what you should know about jaw clicking, what causes it, and when it’s time to schedule a dental evaluation.

What Is the Temporomandibular Joint?

Your temporomandibular joints, commonly called the TMJs, connect your lower jaw to your skull.

You have one joint on each side of your head, located just in front of your ears.

These joints work together with surrounding muscles and ligaments to help you:

• Open and close your mouth
• Chew food
• Speak
• Yawn
• Move your jaw from side to side

The TMJ is a complex joint that allows both rotational and sliding movements.

Inside each joint is a small disc made of cartilage-like tissue. This disc helps cushion the joint and allows the bones to move smoothly.

When the disc or surrounding structures don’t move as expected, you may notice clicking, popping, or other unusual sensations.

Why Does My Jaw Click When I Open My Mouth?

Jaw clicking can occur for several reasons.

One common explanation involves the small disc inside the temporomandibular joint.

Normally, this disc moves with the jaw as you open and close your mouth.

However, in some people, the disc shifts out of its usual position when the mouth is closed and then moves back into place as the jaw opens.

This movement can create a clicking or popping sound.

The condition is sometimes called disc displacement with reduction.

Although the name sounds complicated, it simply describes a disc that temporarily moves out of position and then returns during jaw movement.

Importantly, not everyone with this condition experiences pain or requires treatment.

Common Causes of Jaw Clicking and Popping

Several factors may contribute to clicking or popping sounds in the jaw.

1. Temporomandibular Joint Disorders

Temporomandibular disorders, or TMD, are a group of conditions affecting the jaw joints, surrounding muscles, and related structures.

Symptoms may include:

• Jaw pain or tenderness
• Clicking or popping
• Difficulty opening the mouth
• Jaw stiffness
• Pain while chewing
• Limited jaw movement
• A feeling that the jaw is catching or locking

TMD can involve the joint itself, the surrounding muscles, or both.

However, clicking alone doesn’t necessarily mean you have a disorder that requires treatment.

2. Teeth Grinding and Clenching

Do you wake up with a sore jaw or notice yourself clenching your teeth during stressful situations?

Teeth grinding, also called bruxism, can place additional demands on the jaw muscles and joints.

Some people grind their teeth while sleeping, while others clench during the day.

Bruxism may contribute to muscle soreness, headaches, tooth wear, and jaw discomfort.

Although grinding and clenching can occur alongside TMD symptoms, they aren’t always the direct cause of joint clicking.

Your dentist can look for signs of excessive tooth wear and help determine whether protective treatment may be appropriate.

3. Joint Disc Movement

As mentioned earlier, the disc inside your TMJ helps the jaw move smoothly.

When the disc moves differently than expected, it may produce a clicking sound.

Some people notice a click when opening their mouths and another when closing them.

Others experience occasional popping without discomfort.

If the disc stops returning to its normal position, jaw movement may become limited in some cases.

A professional evaluation can help determine whether the clicking is associated with a functional problem.

4. Arthritis or Joint Changes

Like other joints in your body, the temporomandibular joints can develop degenerative changes.

Conditions such as osteoarthritis may affect the joint surfaces and contribute to discomfort or unusual sounds.

Rather than a distinct click, some people experience a grinding or crackling sensation known as crepitus.

Arthritis-related jaw symptoms may include stiffness, tenderness, or changes in movement.

However, joint sounds alone aren’t enough to diagnose arthritis.

5. Jaw Injury

An injury to the jaw or surrounding structures may affect how the joint functions.

For example, a fall, sports injury, or impact to the face could damage tissues involved in jaw movement.

Following an injury, some individuals experience pain, clicking, swelling, or difficulty opening their mouths.

If jaw symptoms begin after trauma, it’s important to seek an appropriate evaluation.

Is Jaw Clicking Normal?

Occasional jaw clicking without pain or movement limitations is relatively common.

Some people have clicking joints for years without developing significant problems.

In these situations, treatment may not be necessary.

However, jaw clicking deserves attention when it is accompanied by:

• Persistent pain
• Difficulty chewing
• Limited mouth opening
• Jaw locking
• Frequent headaches associated with jaw discomfort
• Changes in how your teeth fit together
• Symptoms that are getting worse

These signs may indicate that the jaw joint or surrounding muscles need further evaluation.

Can Stress Make Jaw Clicking Worse?

Stress can influence how you use your jaw muscles.

When you’re feeling anxious or concentrating intensely, you may unconsciously clench your teeth or hold tension in your face and jaw.

This increased muscle activity can contribute to soreness and discomfort.

For some people, stress-related clenching may make existing jaw symptoms more noticeable.

However, stress doesn’t explain every case of jaw clicking.

TMD is complex, and symptoms may involve physical, behavioral, and other health-related factors.

Relaxation techniques, improved sleep habits, and awareness of daytime clenching may help reduce muscle tension.

Can Chewing Gum Cause Jaw Problems?

Chewing gum requires repeated movement of the jaw muscles and joints.

For most people, occasional gum chewing doesn’t cause a problem.

However, if you’re already experiencing jaw pain or stiffness, prolonged chewing may aggravate your symptoms.

The same may be true for chewing very tough foods or frequently biting hard objects.

If your jaw is uncomfortable, temporarily choosing softer foods and reducing activities that strain the joint may help.

You don’t necessarily need to avoid these activities forever, but giving irritated tissues a chance to settle can be useful.

What Is the Difference Between TMJ and TMD?

These terms are often used interchangeably, but they mean different things.

TMJ stands for temporomandibular joint. Everyone has two TMJs.

TMD stands for temporomandibular disorder, which refers to conditions affecting the jaw joints or surrounding muscles.

For example, saying you have “TMJ” technically refers to the joint itself, while saying you have “TMD” describes a disorder involving that area.

Your dentist can help determine whether your symptoms are associated with a temporomandibular disorder or another condition.

How Does a Dentist Evaluate Jaw Clicking?

If you’re experiencing jaw clicking or popping, your dentist may begin by asking about your symptoms.

They may want to know:

• When the clicking started
• Whether you experience pain
• If your jaw ever locks or catches
• Whether chewing makes symptoms worse
• If you grind or clench your teeth
• Whether you’ve experienced a recent injury

During the examination, your dentist may assess how your jaw moves, check for tenderness, and listen or feel for joint sounds.

They may also examine your teeth for signs of grinding or excessive wear.

Imaging isn’t necessary for every patient with jaw clicking. However, additional evaluation or referral may be recommended when symptoms suggest a more complex joint problem.

How Is Jaw Clicking Treated?

Treatment depends on whether the clicking is causing pain or interfering with normal jaw function.

If your jaw clicks occasionally but doesn’t hurt, your dentist may simply recommend monitoring the symptoms.

When discomfort is present, conservative approaches are often considered first.

Gentle Jaw Exercises

Certain exercises may help improve jaw movement and muscle coordination.

However, exercises should be selected based on your specific condition rather than performed aggressively or without guidance.

Reducing Jaw Strain

Temporarily avoiding gum chewing, very hard foods, and excessive mouth opening may help irritated tissues settle.

Warm or Cold Compresses

Applying a warm or cold compress to the jaw area may help relieve discomfort for some people.

Managing Clenching Habits

If you frequently clench your teeth, becoming more aware of the habit may help reduce unnecessary muscle tension.

Oral Appliances

A dentist may recommend a custom oral appliance for certain patients, particularly when teeth grinding or specific jaw-related symptoms are involved.

Not every patient with jaw clicking needs a nightguard.

Additional Care

Persistent or complex symptoms may require referral to a healthcare professional with advanced training in orofacial pain or temporomandibular disorders.

Irreversible procedures that permanently change the bite generally aren’t recommended solely to treat uncomplicated jaw clicking.

Can Jaw Clicking Go Away on Its Own?

Yes, some cases of jaw clicking improve or become less noticeable over time.

Others may continue without causing pain or functional problems.

The presence of a clicking sound doesn’t necessarily mean the condition will get worse.

If symptoms are mild, conservative care and monitoring may be appropriate.

However, worsening pain, restricted movement, or repeated locking should be evaluated.

When Should You See a Dentist About Jaw Clicking?

If your jaw clicks occasionally without pain, it may not require immediate treatment.

However, schedule a dental appointment if you notice persistent discomfort, difficulty chewing, or changes in jaw movement.

You should also seek evaluation if your jaw frequently catches or locks.

If your mouth becomes stuck open or closed, particularly after an injury, seek prompt medical or dental care.

A proper diagnosis can help prevent unnecessary treatment and identify when additional care is appropriate.
