Jaw Clicking and Popping: What It Means and When to Seek Help

What Is Jaw Clicking and Popping?

The temporomandibular joint is one of the most complex joints in the body. It operates as both a hinge and a sliding joint, allowing your jaw to move up, down, forward, and side to side. A fibrous articular disc sits between the condyle (the rounded end of the jaw bone) and the temporal bone of the skull, acting as a shock absorber and enabling smooth movement.

The clicking sound typically occurs when the articular disc shifts forward from its normal position. As you open your mouth, the jaw condyle slides forward and catches the displaced disc, pulling it back into place with an audible click. A second pop may occur when closing as the disc slips forward again. This reciprocal movement is the most common mechanism behind TMJ sounds.

Occasional jaw clicking is extremely common and affects a significant portion of the adult population at some point. Many people experience joint noise that comes and goes without any other symptoms. Chronic clicking, however — where the sound is consistent, progressive, or accompanied by pain — suggests ongoing disc displacement or changes in the jaw joint mechanics that may benefit from assessment.

Some patients describe a popping sensation rather than a click, while others notice a grinding or gritty feeling known as crepitus. Popping tends to relate to disc displacement, whereas crepitus is more commonly associated with roughening of the joint surfaces from degenerative changes. Distinguishing between these sounds helps your dental team identify the underlying cause.

Why Does My Jaw Click?

There are several reasons why the jaw joint produces clicking or popping sounds. In most cases, more than one factor contributes to the problem, and identifying the specific causes helps guide effective treatment.

Disc Displacement

The most common cause of jaw clicking is anterior disc displacement. The articular disc moves forward from its normal position on top of the condyle. When you open your mouth, the condyle slides forward and recaptures the disc with a click. The disc may slip forward again when you close, producing a second sound. This reciprocal clicking is characteristic of disc displacement with reduction.

Muscle Tension and Tightness

Tight jaw muscles — particularly the lateral pterygoid, masseter, and temporalis — alter the way the joint moves. When muscles on one side are tighter than the other, they can pull the jaw sideways during opening, creating an uneven movement path that produces clicking. Chronic muscle tension from stress, posture, or habits like nail biting can sustain this pattern.

Ligament Laxity

The ligaments supporting the jaw joint help keep the disc and condyle in proper alignment. When these ligaments are naturally loose or have been stretched through injury or repeated wide opening, the joint becomes hypermobile. This excessive range of movement allows the disc to shift more easily, increasing the likelihood of clicking and popping during normal jaw function.

Bite Misalignment

An uneven bite — whether from crooked teeth, missing teeth, or poorly fitting dental work — forces the jaw to compensate by closing in an altered position. This compensation changes the loading pattern on the joint, potentially displacing the disc and creating joint sounds. Correcting the bite alignment can reduce the mechanical strain contributing to clicking.

Arthritis

Osteoarthritis can affect the temporomandibular joint, gradually wearing down the cartilage and bone surfaces. As the smooth joint surfaces roughen, the movement becomes less fluid and produces grinding or crepitus sounds rather than sharp clicks. Rheumatoid arthritis can also cause inflammation within the joint, affecting disc position and overall joint function.

Injury or Trauma

A blow to the jaw, whiplash injury, or forceful impact can damage the articular disc, ligaments, or joint surfaces. Even injuries that seemed minor at the time can alter the internal structure of the joint, leading to clicking or popping that develops weeks or months later. A history of facial trauma is an important factor to mention during your assessment.

Teeth Grinding and Clenching

Chronic bruxism places sustained, excessive force on the temporomandibular joint. The repetitive loading fatigues the muscles, strains the ligaments, and can gradually displace the articular disc. Over time, this leads to joint sounds, tenderness, and reduced function. Managing tooth grinding is often an essential part of addressing persistent jaw clicking.

Jaw Clicking With Pain vs Without Pain

Whether jaw clicking is accompanied by pain makes a significant difference in how it should be managed. Understanding what your symptoms indicate helps you decide when to monitor and when to seek professional advice.

Painless Clicking

• Often harmless if no other symptoms are present — many people live with occasional clicking without any issues
• May not require active treatment, particularly if the clicking is stable and infrequent
• Still worth monitoring for changes in frequency, volume, or the development of new symptoms
• Mentioning it at your next dental examination allows your dentist to establish a baseline

Clicking With Pain

• May indicate inflammation within the joint or significant disc displacement affecting surrounding tissues
• Often accompanied by muscle tenderness in the jaw, face, or temple area
• Pain during eating, yawning, or speaking suggests the joint is under functional stress
• Usually benefits from professional assessment to identify the cause and prevent progression

Clicking With Locking

• The jaw temporarily gets stuck in an open or closed position, requiring gentle manipulation to release
• Indicates more significant disc displacement where the disc blocks normal jaw movement
• If locking episodes become more frequent or last longer, this requires prompt dental attention
• Early treatment can help prevent the condition from progressing to a permanent closed lock

Common Symptoms Accompanying Jaw Clicking

Jaw clicking rarely occurs in complete isolation. When the temporomandibular joint is not functioning optimally, several related symptoms may develop. Recognising the full picture helps your dental team understand the extent of any TMJ dysfunction.

• Jaw pain or tenderness — especially noticeable when chewing, yawning, or opening the mouth wide
• Facial pain — around the ear, cheek, or temple area, often worse on the affected side
• Headaches — often mimicking tension headaches, felt across the temples or behind the eyes on waking
• Ear symptoms — a feeling of fullness, ringing (tinnitus), or ache without any underlying ear infection
• Difficulty chewing — discomfort, weakness, or a feeling that the jaw tires quickly during meals
• Locking — inability to fully open or close the mouth, even temporarily
• Bite changes — feeling that your teeth no longer fit together properly when you close your mouth
• Neck and shoulder tension — associated muscle groups compensating for jaw dysfunction, creating wider patterns of discomfort

What Causes the Jaw Joint to Click or Pop?

Understanding the mechanical processes behind TMJ clicking and popping helps explain why treatments are targeted at specific aspects of joint function.

Articular Disc Displacement

In a healthy joint, the articular disc stays centred on the condyle throughout movement. With disc displacement, the disc shifts forward — usually pulled by the lateral pterygoid muscle attachment.

• The disc moves forward and gets stuck ahead of the condyle when the mouth is closed
• A click occurs when the condyle slides forward during opening and recaptures the disc
• A pop occurs when the disc displaces forward again as the mouth closes

Joint Hypermobility

Some individuals have naturally loose ligaments throughout their body, a condition known as generalised joint hypermobility. When this affects the TMJ, the joint moves beyond its optimal range.

• Loose ligaments allow excessive forward translation of the condyle during opening
• Common in people who can hyperextend their elbows, knees, or fingers
• May produce a loud pop or clunk when the jaw moves beyond its normal range

Muscle Spasm

When jaw muscles go into spasm, they contract involuntarily and pull the joint out of alignment during movement.

• Tight muscles pull the mandible sideways, creating an uneven movement path
• The resulting irregular motion displaces the disc and produces audible joint noise
• Relieving the muscle tension often reduces or eliminates the clicking

Degenerative Changes

Over time, the smooth cartilage surfaces of the joint can wear down, creating roughened areas.

• Cartilage wear creates rough joint surfaces that grate against each other
• Produces a grinding sensation known as crepitus rather than a distinct click
• More common in older adults or following long-standing untreated disc displacement

Is Jaw Clicking Serious?

The seriousness of jaw clicking depends entirely on the accompanying symptoms and the progression of the condition. Here is a practical guide to help you assess your situation.

When it is likely NOT serious:

• No pain or discomfort accompanies the clicking sound
• No episodes of locking in the open or closed position
• No impact on your ability to eat, speak, or yawn comfortably
• The clicking is occasional and has not changed over time

When to take it seriously:

• Pain accompanies the sound, whether sharp or a dull persistent ache
• Your jaw locks in an open or closed position, even briefly
• Difficulty eating, opening your mouth wide, or chewing on one side
• The clicking has become more frequent, louder, or has changed character
• Headaches, ear symptoms, or neck tension have developed alongside the clicking

Diagnosis and Assessment

If jaw clicking is affecting your comfort or function, a thorough clinical assessment helps identify the underlying cause and guides an appropriate treatment approach. Your dental team will carry out several checks during your consultation.

• Medical history review — discussing your symptoms, when they started, what makes them better or worse, and any relevant medical or dental history
• Clinical examination — listening and feeling for joint sounds by placing fingers over the TMJ while you open, close, and move your jaw from side to side
• Range of motion testing — measuring how wide you can open your mouth and whether the jaw deviates to one side during opening
• Bite assessment — evaluating how your teeth come together and checking for occlusal interferences that may stress the joint
• Muscle palpation — checking the masseter, temporalis, and pterygoid muscles for tenderness, trigger points, and tension

Treatment Options for Clicking Jaw

Treatment for jaw clicking depends on whether there is pain, locking, or functional limitation. Many painless clicks need no active treatment at all, while symptomatic clicking benefits from a tailored approach that addresses the specific contributing factors. TMJ treatment in London is available at our City of London practice, where we develop personalised management plans based on your assessment findings.

Self-Care and Home Management

For mild jaw clicking, self-care is often the first step. These approaches can relieve symptoms and reduce joint strain while your dental team monitors progress.

• Eating a softer diet to rest the joint — avoiding hard, chewy, or crunchy foods temporarily
• Applying warm compresses to the jaw muscles for ten minutes, several times daily
• Avoiding wide yawning, chewing gum, and biting into large items like apples
• Practising the “lips together, teeth apart” resting position throughout the day

Jaw Exercises

Specific exercises can help strengthen the muscles that stabilise the jaw joint and improve coordination during movement, reducing the likelihood of disc displacement during function.

• Controlled opening — open your mouth slowly in a straight line using a mirror as a guide, stopping before the click occurs
• Resistance exercises — place gentle pressure against your chin while opening to build muscle strength and control
• Lateral movements — gently move your jaw side to side against light finger resistance to strengthen lateral stabilisers
• Tongue-up exercises — place your tongue on the roof of your mouth and open slowly, which helps guide the jaw into a centred position

Night Guards and Splints

Custom occlusal splints worn during sleep reduce the muscle tension and joint loading caused by nocturnal grinding and clenching. By creating a stable, even biting surface, they allow the jaw muscles to relax and reduce the forces transmitted to the joint.

• Protects teeth from grinding damage while reducing joint strain
• Custom-fitted for maximum comfort and effectiveness
• Particularly beneficial when bruxism is contributing to jaw clicking

Stress Management

Since stress-related jaw tension is a significant contributor to clicking, incorporating relaxation techniques into your daily routine can make a meaningful difference. Mindfulness meditation, progressive muscle relaxation, and breathing exercises all help reduce unconscious clenching throughout the day. Developing awareness of when you hold tension in your jaw allows you to intervene before symptoms escalate.

Physiotherapy

When jaw clicking is linked to significant muscle dysfunction or restricted movement, specialist jaw physiotherapy can be highly effective. A physiotherapist experienced in TMJ conditions uses manual therapy, targeted exercises, and postural correction to restore balanced jaw function. Your dental team can guide you toward an appropriate referral when physiotherapy would benefit your management plan.

Bite Correction

When misaligned teeth or an uneven bite contribute to jaw clicking, correcting the alignment can reduce the mechanical strain on the joint. Orthodontic treatment improves how your teeth fit together, allowing the jaw to close in a more natural, balanced position.

• Corrects malocclusion that forces the jaw to compensate during closure
• Reduces uneven loading on the temporomandibular joint
• May be combined with other approaches for comprehensive management

Restorative Dental Treatment

Uneven fillings, poorly fitting crowns, or missing teeth can all create bite imbalances that stress the jaw joint. Restorative dentistry can adjust or replace dental work that disrupts your bite harmony, as well as replace missing teeth to restore proper occlusal balance.

• Adjusting high spots on fillings or crowns that interfere with even closure
• Replacing missing teeth to improve bite distribution and joint loading
• Rebuilding worn or damaged teeth to restore proper occlusal contacts

Jaw Clicking Before and After

With appropriate management, patients with jaw clicking can experience meaningful improvements in comfort and function. Outcomes vary depending on the underlying cause and severity, but realistic expectations include:

• Reduced or eliminated clicking and popping sounds during jaw movement
• Improved jaw movement range with smoother, more comfortable opening
• Decreased pain and discomfort in the jaw, face, and temple area
• Better chewing function and confidence during meals
• Fewer headaches and reduced muscle tension in the jaw and neck

Can Jaw Clicking Go Away on Its Own?

Many cases of painless jaw clicking do resolve or become less noticeable over time, particularly when the clicking is related to temporary muscle tension, a period of heightened stress, or a minor change in jaw habits. The joint can adapt, and the disc may settle into a more stable position without intervention.

However, clicking that is accompanied by pain, locking, or progressive difficulty with jaw function is less likely to resolve without treatment. The underlying causes — whether disc displacement, bite issues, or degenerative changes — typically require targeted management to prevent the condition from worsening.

In some cases, a clicking jaw that suddenly stops clicking without improvement in other symptoms may indicate that the disc has permanently displaced and is no longer recapturing. This is known as disc displacement without reduction and may be accompanied by restricted opening. It is important to mention this change to your dental team.

Monitoring your symptoms and maintaining good jaw habits — avoiding excessive chewing, managing stress, and keeping your teeth slightly apart at rest — gives the joint the best chance of natural improvement while preventing aggravation.

When to See a Dentist About Jaw Clicking

While occasional painless clicking may not require urgent attention, the following signs indicate that a professional assessment would be beneficial:

• Clicking is accompanied by pain in the jaw, face, or temple area
• Your jaw locks in an open or closed position, even if only briefly
• Difficulty eating, opening your mouth fully, or chewing comfortably
• The clicking has become more frequent, louder, or has changed in character
• Headaches or ear symptoms have developed alongside the jaw sounds
• Your bite feels different or your teeth no longer fit together comfortably
• Self-care measures have not improved your symptoms after a few weeks
