Jaw Clicking: Common Causes, Symptoms, and Triggers

What Is Jaw Clicking?

Jaw clicking is not uncommon in adults. Like other joints in the body, the temporomandibular joint (TMJ) is subject to wear and tear over time. Everyday movement, muscle tension, and joint strain can all contribute to sounds such as clicking, popping, or cracking.

Jaw clicking is most often heard or felt near the ear when chewing, yawning, or opening and closing the mouth. The “click” typically occurs when the jaw joint’s articular disc (which sits between the jawbone and the skull) momentarily slips out of position and then moves back into place. Clicking may happen occasionally or every time you move your jaw, and it can occur on one or both sides.

The amount of pain associated with jaw clicking varies. Some people experience no discomfort at all, while others notice tension, soreness, or pain. Pain level and frequency are often the clearest indicators of whether treatment or lifestyle changes may be needed.

Jaw Clicking vs. Jaw Popping

Clicking and popping are often used interchangeably in reference to the TMJ, but they are not always the same thing.

• Jaw clicking is usually subtler, repetitive, and may occur earlier in TMJ dysfunction. It’s often noticed as a light sound or sensation during jaw movement.
• Jaw popping tends to be louder or more pronounced and is more commonly associated with noticeable joint movement or disc displacement. Read more about jaw popping here.

Clicking without pain may simply need monitoring, while frequent popping or clicking accompanied by discomfort can signal a progressing TMJ issue.

Is Jaw Clicking Normal?

If your hear clicking but don’t experience pain, and it doesn’t interfere with chewing, speaking, or daily function, it’s reasonable to monitor it. Let your dentist know so they can keep an eye on any changes during routine visits.

However, if the clicking becomes painful, frequent, or disruptive, it may be a sign of TMJ disorder. TMJ dysfunction can lead to a cluster of symptoms, including jaw clicking or popping, headaches, facial tenderness, and neck pain. Catching symptoms early and practicing supportive self-care may help prevent flare-ups from becoming more severe.

Side Effects of Jaw Clicking

Painful jaw clicking rarely exists on its own. It’s often one of several symptoms related to an irritated or inflamed temporomandibular joint. Other symptoms may include:

• Pain while chewing
• Decreased range of motion
• Jaw popping
• Teeth grinding
• Jaw clenching
• Facial pain or tenderness
• Neck pain
• Dull or sharp headaches
• Ear fullness or earaches
• Open or closed locked jaw

Symptoms may fluctuate depending on daily activity, posture, stress, and diet. Becoming aware of habits that aggravate the jaw can help reduce overall discomfort.

Common Causes of Jaw Clicking

Although clicking is often related to disc movement within the jaw joint, several underlying factors may contribute.

Arthritis

Arthritis can damage the cartilage that cushions joints, including the TMJ. Clicking may occur in people with rheumatoid arthritis (RA) or osteoarthritis (OA), and repetitive movements like clenching or grinding can further irritate the joint. Imaging such as an MRI can help determine whether arthritis is contributing.

Malocclusion or Misaligned Bite

A misaligned bite is a common contributor to jaw clicking. Overbites, underbites, open bites, and crowded teeth can all cause the lower jaw to overcompensate during movement, leading to clicking, popping, or discomfort over time.

Disc Displacement

The disc that supports jaw movement can shift due to trauma, strain, or gradual wear and tear. Injuries from sports, car accidents, or falls may contribute, but displacement can also occur without a single obvious event.

Poor Posture

Poor posture (particularly a rounded shoulders and a forward head position) can alter the resting position of the jaw. When the spine is misaligned, the jaw joints are pushed out of their optimal position, increasing strain and contributing to TMJ symptoms. Certain exercises may exacerbate this posture or add additional stress to the joints. Improving posture is often a foundational step in jaw health.

Habits That Can Worsen Jaw Clicking

Whether jaw clicking is painful or not, it’s helpful to reduce habits that place unnecessary strain on the jaw joint. Common contributors include:

• Chewing gum
• Eating hard or tough foods
• Biting fingernails or chewing on objects
• Jaw clenching
• Teeth grinding
• Excessive yelling or screaming
• Sleeping on the stomach or improper side sleeping
• Sitting with poor, slouched posture

Managing Jaw Clicking Long-Term

While jaw clicking can’t always be reversed at home, supportive self-care can reduce strain on the joint and lower the likelihood of progression. Paying attention to posture, stress levels, jaw habits, and sleep positioning can go a long way toward protecting long-term jaw health.

A few small changes can make a meaningful difference over time.

If you’re exploring over-the-counter and readily available treatment options, here are some popular recommendations:

• A nightguard for clenching and grinding
• Neck and shoulder posture relaxer
• Facial heating pad to manage pain
