TMJ Disorder (Temporomandibular Joint Dysfunction)

Jaw pain can significantly affect daily life. If you are experiencing discomfort when chewing, speaking or opening your mouth, you may be dealing with TMJ disorder.

Temporomandibular joint dysfunction (TMJ disorder), sometimes referred to as TMJ syndrome or TMD, affects the joint that connects your jaw to your skull. When this joint or the surrounding muscles are irritated or strained, it can lead to persistent pain, headaches and restricted jaw movement.

Lumino dentists provide assessment and conservative TMJ treatment options across New Zealand. Early evaluation can help prevent symptoms from worsening and reduce the risk of chronic TMJ pain.

What Is TMJ?

The temporomandibular joint (TMJ) is a specialised synovial joint located on each side of your jaw. It connects your lower jaw to your skull and allows both hinging and sliding movements, enabling you to speak, chew and yawn smoothly.

TMJ disorder occurs when this joint or its surrounding muscles do not function properly. TMJ dysfunction may be linked to:

  • Teeth clenching or grinding (bruxism)

  • Stress-related muscle tension

  • Bite misalignment

  • Jaw injury or trauma

  • Arthritis in the TMJ joint

  • Disc displacement within the joint

While many people use the term “TMJ” to describe the condition, TMJ refers to the joint itself. The disorder is technically called temporomandibular joint disorder or TMJ dysfunction.

Common TMJ Symptoms

TMJ symptoms can vary in severity and may develop gradually or suddenly.

Common symptoms include:

  • Jaw pain or tenderness

  • Clicking, popping or grinding sounds when opening the mouth

  • Difficulty chewing

  • Locking of the jaw (open or closed lock)

  • Limited jaw movement

  • TMJ headache, particularly around the temples

  • Ear pain or pressure

  • Facial pain or neck discomfort

Some patients may also experience dizziness, ringing in the ears (tinnitus), or pain on one side of the jaw.

If you are experiencing persistent TMJ symptoms, a dental assessment can help determine whether the issue relates to the joint, the muscles, or your bite.

 

TMJ Treatment Options

In most cases, TMJ treatment focuses on conservative, non-surgical approaches. The goal is to reduce inflammation, relieve muscle tension and protect the joint from further strain.

Treatment options may include:

Bite Splints or Night Guards

A custom-made TMJ splint or night guard may be recommended to reduce teeth grinding and relieve pressure on the joint. These appliances are designed specifically for your bite.

Jaw Exercises

Targeted TMJ exercises can improve jaw mobility and strengthen supporting muscles. Your dentist may provide guidance or refer you for physiotherapy where appropriate.

Pain Relief & Anti-Inflammatory Medication

Short-term use of anti-inflammatory medication may help manage flare-ups.

Stress Management

Because TMJ and stress are closely linked, relaxation techniques can play an important role in managing symptoms.

Orthodontic Assessment

In some cases, bite correction or orthodontic treatment may be discussed if alignment issues contribute to TMJ dysfunction.

Surgical intervention or advanced procedures such as arthrocentesis or TMJ surgery are typically reserved for severe cases and would involve referral to an appropriate specialist.

What to Expect at Your Appointment

Appointments

Most patients require at least two appointments.

At your initial consultation, your dentist will:

  • Assess your jaw movement

  • Examine your bite

  • Review your dental and medical history

  • Discuss your TMJ pain and symptom history

If an oral appliance is recommended, impressions may be taken for fabrication of a custom splint.

Follow-up visits are typically required to review fit, comfort and symptom improvement.

 

How Long It Takes

Consultations usually take around 30 minutes. If impressions are required, the appointment may take longer.

Adjustment to a splint or night guard can take several weeks. Improvement in TMJ symptoms often occurs gradually with consistent use.

Before Your Appointment

No special preparation is required. It may help to note:

  • When your TMJ pain began

  • What triggers symptoms

  • Whether you experience TMJ headaches or ear discomfort

  • Any history of jaw injury

 

After Your Appointment

If prescribed a splint or night guard, follow your dentist’s care instructions carefully. Some temporary discomfort may occur while adjusting to the appliance.

Monitoring changes in symptoms over time can be helpful in evaluating treatment effectiveness.

TMJ FAQs

TMJ disorder refers to dysfunction of the temporomandibular joint, which connects the jaw to the skull. It can cause jaw pain, headaches, clicking sounds and restricted movement.

Mild TMJ dysfunction may improve without treatment. However, persistent or worsening symptoms should be assessed to prevent chronic jaw pain or long-term joint issues.

While many cases are manageable, untreated TMJ disorder can lead to chronic pain, limited jaw function and ongoing headaches. Early conservative TMJ treatment can improve outcomes.

The cost of treating TMJ disorder varies depending on the recommended approach, such as splint therapy or orthodontic treatment. A consultation is required to provide an accurate estimate.
