TMJ Jaw Injuries: Symptoms, Treatment and Your Legal Rights

Looking for experienced TMJ lawyers in California or dealing with jaw pain, clicking or a locked jaw after a car accident, Walch Law can help. For more than 50 years, our Personal Injury Attorneys have represented Californians injured in car accidents, motorcycle accidents, truck accidents and pedestrian accidents  — including hard-to-diagnose injuries like TMJ that insurance companies often try to dismiss.

A blow from an airbag, a hard jolt to the face or violent whiplash can damage the temporomandibular joint (TMJ), causing pain, clicking, headaches and limited jaw movement that may last for months or even years. If you have suffered a TMJ injury in California, Walch Law’s Personal Injury Attorneys have more than 50 years of experience helping injured Californians document difficult-to-diagnose injuries and hold negligent parties accountable. Please contact us now for your FREE consultation and case evaluation or you may also call us at 818-222-3400 (again, after hours, please dial “1”). — There is no fee unless we win your case.

What Is the Temporomandibular Joint?

The temporomandibular joint sits just in front of each ear, where the lower jawbone (the mandible) meets the temporal bone at the side of the skull. Unlike most joints in the body, the TMJ works as a matched pair — both sides move together every time you talk, chew, swallow or yawn. A rounded structure at the top of the jawbone, called the condyle, glides within a socket in the temporal bone. A small cartilage disc cushions that motion so the joint moves smoothly rather than grinding bone against bone.

Because the TMJ combines a hinge motion with a sliding motion and is surrounded by a dense network of nerves, ligaments and muscles, it is considered one of the most mechanically complex joints in the human body — and one of the most vulnerable to trauma.

How Car Accidents Cause TMJ Injuries

TMJ injuries are common in California car, motorcycle, truck, rideshare  and pedestrian accidents, yet they are frequently overlooked in the chaos of the emergency room, where the priority is ruling out fractures and internal injuries. Typical mechanisms include:

• Direct impact — the jaw or face striking a steering wheel, dashboard, window or door frame
• Airbag deployment — the force of a deploying airbag striking the jaw or face at high speed
• Whiplash — the rapid back-and-forth motion of a rear-end collision that snaps the jaw open and shut, straining the joint and surrounding ligaments
• Clenching — an instinctive jaw-clenching reflex at the moment of impact, which can strain the joint even without a direct blow
• Falls and pedestrian impacts — a fall or a strike from a vehicle that transmits force directly through the jaw and skull

Warning Signs and Symptoms of a TMJ Injury

Only a physician or qualified TMJ specialist can accurately diagnose a jaw joint injury, but the following symptoms are common warning signs that should prompt an evaluation, especially after any recent collision:

• Clicking, popping or grinding sounds when opening or closing the mouth
• The jaw locking, catching or feeling “stuck” open or closed
• Pain or difficulty chewing, biting or opening the mouth fully
• Dull, aching or sharp pain in the face, especially upon waking
• Frequent headaches or migraines
• Ringing in the ears (tinnitus) or new hearing problems
• Pain radiating into the neck, shoulders or upper back
• Sinus pressure or facial stuffiness
• Dizziness or balance problems
• Tooth sensitivity or a change in how the teeth fit together
• Increased light sensitivity
• Mood changes, irritability or symptoms of depression tied to chronic pain

Why TMJ Injuries Are Often Missed — and Why That Matters for Your Claim

Jaw pain does not always appear immediately. Adrenaline, inflammation and the focus on more obvious injuries can delay TMJ symptoms by days or even weeks after a crash. That delay is medically well documented, but it is also exactly what insurance adjusters look for when they try to argue that a jaw injury is unrelated to the collision. Prompt medical evaluation — and a clear, written record connecting your symptoms to the crash — is one of the most important things you can do to protect both your health and your claim.

How TMJ Injuries Are Diagnosed

A thorough evaluation typically involves a physical examination of jaw movement and joint sounds, a review of bite alignment, and imaging such as an MRI or CT scan to assess the disc, condyle and surrounding soft tissue. Many accident victims are referred from their primary treating physician to an oral and maxillofacial specialist, orofacial pain dentist, or TMJ specialist for a definitive diagnosis and treatment plan.

Treatment Options for TMJ Injuries

There is no single best treatment for TMJ injuries and the right approach often depends on the severity of the injury and how the individual patient responds. A treating specialist may recommend a combination of the following:

Conservative Treatment

• A custom mouth splint or bite-repositioning appliance
• Moist heat or cold therapy
• Trigger point injections to relieve muscle spasm
• Physical therapy and guided jaw-stretching exercises
• Anti-inflammatory or muscle-relaxant medication

Conservative care is generally the first line of treatment and when successful, commonly runs for four to nine months before symptoms stabilize.

Surgical Treatment

When conservative treatment does not resolve the injury, options range from minimally invasive arthrocentesis and arthroscopy to open-joint surgery, followed by a structured course of rehabilitation and physical therapy. Even with excellent treatment, some TMJ injury victims are left with permanent limitations because of how delicate and nerve-rich this joint is.

Common Mistakes Accident Victims Make with TMJ Injuries

• Waiting to see if the pain “goes away on its own” instead of getting evaluated promptly
• Not mentioning jaw pain, clicking or headaches to the treating doctor because it seems minor compared to other injuries
• Accepting a fast, low settlement offer from the insurance company before the full extent of the injury is known
• Failing to keep a symptom journal documenting pain, jaw locking episodes and limitations
• Missing follow-up appointments, which insurers use to argue the injury was not serious

Common Insurance Company Tactics With TMJ Claims

Because TMJ injuries do not always show up clearly on X-rays and often involve delayed or fluctuating symptoms, insurance companies frequently dispute these claims. Common tactics include arguing that the jaw pain is a pre-existing condition, pointing to any gap in treatment as proof the injury was not serious, sending claimants to an insurer-selected “independent” medical exam designed to minimize findings and offering a quick, low settlement before the long-term impact of the injury is known. An experienced attorney can push back on each of these tactics with medical documentation, specialist testimony and a well-prepared claim.

Damages Available in a California TMJ Injury Claim

A TMJ injury can entitle you to compensation for both financial losses and the impact on daily life, including:

• Past and future medical expenses (imaging, specialists, splints, surgery)
• Lost wages and lost earning capacity
• Pain and suffering
• Loss of enjoyment of life activities
• Emotional distress

California Law and Your Legal Rights

California law gives injured accident victims specific rights and specific deadlines. Two of the most important rules to understand are:

• Statute of limitations: Under California Code of Civil Procedure § 335.1, most personal injury claims — including TMJ injury claims from a car accident — must generally be filed within two years of the date of the injury. Claims against a government entity have a much shorter deadline, often six months, to file an initial claim.
• Comparative negligence: California follows a pure comparative negligence rule (established in Li v. Yellow Cab Co.), which means an injured person can still recover compensation even if they were partly at fault for the accident — their recovery is simply reduced by their percentage of fault.

Because TMJ injuries can be difficult to link conclusively to a specific crash, thorough medical documentation and, where appropriate, expert testimony are essential to proving causation and the true value of the claim.
