Why Does My Lower Jaw Click When Chewing Possible Causes And Remedies

If you've noticed a clicking or popping sound coming from your lower jaw every time you chew, speak, or yawn, you're not alone. Millions of people experience jaw noise at some point in their lives. While occasional clicking may be harmless, persistent or painful jaw sounds can signal an underlying issue that deserves attention. The temporomandibular joint (TMJ), which connects your jawbone to your skull, is one of the most complex joints in the body. It allows for smooth movement during talking, eating, and swallowing—but when it becomes misaligned, inflamed, or strained, it can produce noticeable noises and discomfort.

This article explores the most common reasons behind jaw clicking during chewing, identifies risk factors, and offers science-backed strategies to manage symptoms. Whether your jaw clicks quietly or comes with pain and limited motion, understanding the root cause is the first step toward relief.

Understanding the Temporomandibular Joint (TMJ)

The temporomandibular joint acts like a sliding hinge, enabling your jaw to move up and down, side to side, and forward and back. A small disc of cartilage sits between the jawbone and the skull socket, cushioning the joint and ensuring smooth motion. When this disc becomes displaced, worn, or inflamed, the joint may not glide properly, leading to audible clicks, pops, or grating sensations.

Jaw clicking occurs when the disc temporarily slips out of place during movement and then snaps back. This often happens during chewing because repetitive motion increases stress on the joint. In many cases, the sound is painless at first but can progress to discomfort, muscle fatigue, or even locking of the jaw if left unaddressed.

“Jaw clicking isn’t always a medical emergency, but it’s a warning sign. Think of it like a squeaky wheel—it might keep turning, but ignoring it could lead to bigger problems.” — Dr. Lena Torres, Oral & Maxillofacial Specialist

Common Causes of Jaw Clicking During Chewing

Several anatomical, behavioral, and physiological factors can contribute to jaw clicking. Some are temporary and resolve on their own; others require professional intervention.

1. Disc Displacement in the TMJ

The most frequent structural cause of jaw clicking is internal derangement of the TMJ, where the articular disc shifts out of its normal position. As the jaw opens or closes, the condyle (the rounded end of the jawbone) moves over the displaced disc, creating a pop or click. This may happen consistently on one side or alternate between both sides.

2. Muscle Tension and Bruxism

Clenching or grinding your teeth—especially at night (a condition known as sleep bruxism)—puts excessive strain on the jaw muscles and joints. Over time, this can irritate the TMJ and lead to clicking. Daytime clenching due to stress or concentration also contributes. People who work long hours at computers or engage in high-focus tasks often unconsciously tighten their jaw, increasing wear on the joint.

3. Arthritis in the Jaw Joint

Osteoarthritis or rheumatoid arthritis can affect the TMJ just like other joints in the body. Cartilage breakdown leads to rougher joint surfaces, resulting in grinding or clicking sounds. Arthritic changes are more common in older adults but can occur earlier in those with autoimmune conditions.

4. Trauma or Injury

A direct blow to the jaw, whiplash, or even dental procedures requiring prolonged mouth opening can damage the TMJ. Such trauma may dislocate the disc or stretch supporting ligaments, causing instability and abnormal joint sounds during chewing.

5. Poor Posture and Neck Alignment

Forward head posture—common among desk workers and smartphone users—alters the alignment of the cervical spine and jaw. This misalignment can pull the mandible out of optimal positioning, increasing pressure on the TMJ and contributing to clicking during movement.

Tip: Pay attention to jaw sounds when they occur. If clicking only happens once per cycle (e.g., one pop when opening, none when closing), it may indicate early disc displacement. Multiple pops suggest more advanced joint degeneration.

When to Be Concerned: Red Flags to Watch For

Not all jaw clicking requires immediate treatment. However, certain symptoms indicate that professional evaluation is necessary:

• Pain in the jaw, face, ear, or temple during chewing or at rest
• Difficulty opening the mouth fully (limited range of motion)
• Jaw locking—either open or closed position
• Swelling around the joint area
• Headaches or earaches without another clear cause
• Asymmetrical jaw movement (jaw veers to one side when opening)

These signs may point to progressive TMJ disorder, inflammatory arthritis, or severe disc displacement. Left untreated, chronic TMJ dysfunction can lead to permanent joint damage, chronic pain syndromes, or degenerative changes visible on imaging.

Evidence-Based Remedies and Management Strategies

Most mild-to-moderate cases of jaw clicking can improve with conservative care. The goal is to reduce inflammation, correct biomechanical imbalances, and minimize behaviors that aggravate the joint.

Diet and Chewing Modifications

Changing how and what you eat can significantly reduce strain on the TMJ:

• Avoid hard, chewy, or large foods (e.g., bagels, tough meats, raw carrots)
• Cut food into small pieces to limit wide jaw opening
• Chew evenly on both sides of the mouth to prevent uneven loading
• Avoid gum chewing and nail biting

Jaw Exercises and Physical Therapy

Specific exercises can help reposition the disc, strengthen supporting muscles, and improve coordination:

1. Resisted Opening: Place your thumb under your chin and gently press upward as you slowly open your mouth. Resist the movement slightly to build control.
2. Lateral Jaw Movement: Slide your lower jaw to the right and left against light finger resistance to improve joint tracking.
3. Posture Correction: Practice chin tucks while sitting upright to align the head over the spine and reduce jaw strain.

Perform these 2–3 times daily for 5–10 minutes. Stop if pain increases.

Stress Reduction and Behavioral Changes

Since emotional stress is a major trigger for jaw clenching, managing it is crucial:

• Practice mindfulness meditation or deep breathing exercises
• Use biofeedback devices that alert you to daytime clenching
• Establish a nighttime routine to wind down before bed

Night Guards and Dental Appliances

A custom-fitted occlusal splint (night guard) worn during sleep can prevent tooth grinding and reduce pressure on the TMJ. Unlike over-the-counter versions, professionally made guards are molded to your bite and offer better protection and comfort.

“About 70% of patients with TMJ-related clicking see improvement within six weeks of consistent night guard use—especially when combined with behavioral changes.” — Dr. Aaron Kim, Prosthodontist

Medical and Professional Treatments

When self-care measures aren’t enough, clinical interventions may be necessary.

Treatment	How It Helps	Typical Duration
Physical Therapy	Manual therapy, ultrasound, and guided exercises restore joint function	4–12 weeks
Orthodontic Adjustment	Corrects bite imbalances contributing to TMJ strain	Months to years
Corticosteroid Injections	Reduces inflammation in severe or arthritic cases	Short-term relief
Surgery (rare)	Repositions or replaces damaged disc in advanced cases	Long recovery

Imaging such as MRI or CBCT scans may be used to assess disc position and rule out structural damage. These are typically reserved for persistent or worsening symptoms.

Mini Case Study: Recovery Through Multimodal Care

Sarah, a 34-year-old graphic designer, began noticing a distinct click in her right jaw while eating sandwiches. At first, it was painless, but after several months of working late and grinding her teeth at night, she developed facial pain and difficulty opening her mouth wide.

She visited a dentist specializing in TMJ disorders, who diagnosed anterior disc displacement without reduction. Sarah was fitted with a custom night guard, prescribed daily jaw exercises, and referred to a physical therapist for manual therapy. She also started using a standing desk and practicing daily neck stretches to correct her forward head posture.

Within eight weeks, her clicking reduced significantly, and pain subsided. After three months, she could chew normally again. Follow-up imaging showed partial disc repositioning. Her success highlights the importance of addressing both mechanical and lifestyle factors.

Frequently Asked Questions

Is jaw clicking dangerous?

Occasional, painless clicking is usually not dangerous and may resolve on its own. However, if it's accompanied by pain, limited motion, or locking, it could indicate a progressive TMJ disorder that needs treatment to prevent long-term damage.

Can jaw clicking go away on its own?

Yes, especially if caused by temporary muscle strain or minor disc displacement. Resting the jaw, avoiding hard foods, and reducing stress can allow natural healing. But if symptoms persist beyond a few weeks, professional care is recommended.

Should I see a dentist or doctor for jaw clicking?

Start with a dentist experienced in TMJ disorders. They can evaluate your bite, joint function, and recommend imaging if needed. In complex cases, referral to an oral surgeon, physical therapist, or rheumatologist may be necessary.

Take Action Before It Gets Worse

Your jaw is designed for thousands of movements each day—chewing, speaking, swallowing. When it starts sending signals like clicking, don't dismiss them as normal wear and tear. Early intervention can prevent minor irritation from becoming chronic pain. Start with simple changes: adjust your diet, practice awareness of clenching, and improve your posture. If symptoms continue, seek professional guidance. With the right approach, most people regain smooth, silent jaw function and avoid long-term complications.
