TMJ Management and Surgery in Sydney
The Temporomandibular Joint (TMJ) plays an essential role in talking, chewing, and daily function. Problems with this joint often called Temporomandibular Disorders (TMD) can cause pain, stiffness, or restricted movement. For many patients, non-surgical options provide relief, while others may require surgery.
With more than 15 years of specialist practice, Dr Kristian van Mourik provides comprehensive TMJ management at clinics in Bondi Junction and Lindfield.
Our practice provides a wide scope of oral and maxillofacial surgery in Sydney, built on more than 15 years of specialist experience. With two established clinics and a patient-first approach, we focus on careful planning, clear communication, and safe surgical care. Learn more about our team and history in the link below
What is the TMJ Joint?
Your temporomandibular joint (TMJ) connects your lower jaw to your skull on each side of your head. It’s one of the most complex joints in the body, allowing you to talk, chew, and yawn comfortably. The joint connects the mandibular condyle (jawbone) to the temporal bone (skull).
TMJ disorders can occur due to arthritis, injury, teeth grinding or clenching (bruxism), or a misaligned bite. While most TMJ problems can be treated without surgery, about 5% of people with severe cases may need a surgical procedure.
Jaw Pain Specialist in Sydney
Jaw pain can range from mild discomfort to severe, chronic pain that affects eating, speaking, and sleep. As a specialist Oral and Maxillofacial Surgeon, Dr van Mourik assesses the full range of jaw pain causes including TMJ dysfunction, muscle tension, bite misalignment, and arthritis of the jaw joint.
Many patients visiting our Sydney clinics have already seen multiple practitioners without a clear diagnosis. Dr van Mourik uses cone beam CT imaging and a comprehensive clinical assessment to identify the exact source of jaw pain and recommend the most appropriate treatment, whether that is non-surgical management or surgical correction.
Common symptoms that bring patients to our jaw pain clinic include:
- Persistent aching around the jaw, ear, or temple
- Pain that worsens when chewing or opening the mouth wide
- Jaw stiffness first thing in the morning
- Referred pain into the neck, shoulders, or headaches
- A feeling that the jaw is stuck or locked
If you are experiencing any of these symptoms, book a consultation at our Bondi Junction or Lindfield clinic.
Jaw Clicking Specialist in Sydney
Jaw clicking, popping, or grating sounds when opening or closing the mouth are among the most common signs of TMJ dysfunction. While occasional clicking is not always painful, persistent or worsening clicking often indicates a displaced disc within the TMJ joint that requires assessment.
Dr van Mourik is a jaw clicking specialist in Sydney with extensive experience diagnosing and treating disc displacement and joint instability. Not all clicking requires surgery. In many cases, splint therapy, physiotherapy, and lifestyle changes are effective first-line treatments.
When clicking is accompanied by pain, locking, or limited mouth opening, further investigation is recommended. Dr van Mourik will assess whether the clicking is caused by:
- Disc displacement with or without reduction
- Joint hypermobility or instability
- Early-stage arthritis of the TMJ
- Muscle dysfunction or clenching habits
A 3D scan and clinical assessment at our Sydney clinic will determine the cause and the right treatment path for your case.
How to Diagnose TMJ Disorders
Dr van Mourik will begin with a thorough clinical examination to assess your jaw movement, bite, and areas of tenderness.
You may also need diagnostic imaging such as:
- Dental X-rays – to evaluate teeth and jaw alignment
- CT scans – to show detailed bone structure
- MRI scans – to reveal issues with the TMJ disc or soft tissues
In some cases, a TMJ arthroscopy is performed for diagnosis. This involves inserting a fine camera (arthroscope) into the joint space to view and assess the structures directly. TMJ arthroscopy can also be used therapeutically to remove inflamed tissue or scar tissue, improving jaw movement and reducing pain.
As a specialist Oral and Maxillofacial Surgeon with dual medical and dental qualifications, Dr van Mourik is one of the most highly qualified practitioners in Australia to assess and treat TMJ disorders at both the surgical and non-surgical level.
What are the Treatment Options for TMJ Pain?
TMJ management starts with a thorough assessment using clinical examination and advanced imaging such as CT or MRI scans. These provide detailed insight into the joint, muscles, and surrounding structures, allowing treatment to be tailored to each patient.
Conservative management options include:
- Self-care and lifestyle changes: Apply heat or ice, avoid gum chewing and extreme jaw movements, practise relaxed jaw posture, and manage stress.
- Medications: Pain relievers, anti-inflammatories, muscle relaxants, or low-dose tricyclic antidepressants may reduce pain and muscle tension.
- Oral splints or mouthguards: Worn at night to reduce grinding and jaw strain.
- Physiotherapy: Jaw stretching and strengthening exercises, ultrasound therapy, or TENS (transcutaneous electrical nerve stimulation).
- Counselling: Addresses habits that worsen TMJ pain, such as clenching or nail-biting.
- Injections: Corticosteroid or botulinum toxin (Botox®) injections may provide relief by reducing inflammation and muscle tension. These effects are usually noticeable within 2 weeks.
Surgical options may be considered if symptoms persist:
- Arthrocentesis (Joint Washout)
A minimally invasive procedure that flushes the joint using sterile fluid to remove debris and inflammatory byproducts. It helps reduce pain and improve jaw mobility.
- Arthroscopy
A small incision is made in front of the ear and a fine arthroscope (camera) is inserted to view the joint. Damaged tissue can be repaired, and inflammation can be treated. This technique has fewer risks and a shorter recovery time than open surgery.
- Arthrotomy (Open-Joint Surgery)
An open approach allows the surgeon to visually examine the joint and perform repairs or tissue biopsies. This option is typically for more complex TMJ conditions.
- Modified Condylotomy
This procedure addresses the TMJ indirectly through surgery on the lower jawbone (mandible), rather than inside the joint itself, to ease pain and locking.
- Total Joint Replacement
When other treatments fail, the damaged TMJ may be replaced with a custom metal prosthesis. This is a major surgery performed under general anaesthetic in a private hospital, with a longer recovery period.
How long does treatment take?
Minimally invasive treatments such as arthrocentesis are usually performed as day procedures, with recovery in just a few days. More complex surgeries, such as open joint surgery, require longer healing times and follow-up care.
Will I be awake during treatment?
Comfort is prioritised for every patient. Depending on the type of procedure, local anaesthetic, intravenous sedation, or general anaesthesia may be used.
Non-Surgical TMJ Treatments
Surgery is not the first step for most TMJ patients. The majority of TMJ disorders respond well to conservative, non-surgical management. Dr van Mourik takes an evidence-based approach, starting with the least invasive treatment appropriate for your diagnosis.
Occlusal splint therapy A custom-made splint worn at night reduces the load on the TMJ and surrounding muscles. Splints are one of the most widely used and effective treatments for TMD, particularly for patients with clenching or grinding habits.
Physiotherapy and jaw exercises Targeted exercises help retrain jaw movement, reduce muscle tension, and improve joint stability. Physiotherapy is often used alongside splint therapy for the best outcomes.
Medication Anti-inflammatory medications, muscle relaxants, and low-dose antidepressants can help manage pain and muscle overactivity in the short term.
Arthrocentesis A minimally invasive procedure where the joint is flushed with sterile fluid to reduce inflammation and improve movement. Performed under local anaesthetic, arthrocentesis is suitable for patients with acute joint locking or persistent pain that has not responded to conservative care.
Botox for jaw clenching Botulinum toxin injections into the masseter muscles reduce the force of clenching and grinding, providing relief for muscle-related TMD and associated headaches.
When is non-surgical treatment enough? For most patients with disc displacement, myofascial pain, or early-stage TMD, non-surgical treatment provides significant or complete relief. Dr van Mourik will discuss realistic expectations for your specific diagnosis at your consultation.
When is TMJ Surgery Recommended?
Surgery is generally only considered when non-surgical treatments have not relieved symptoms. It may be recommended when:
- Pain continues to interfere with daily activities despite conservative management.
- The jaw locks open or closed, restricting normal function.
- Clicking, popping, or grinding noises are associated with limited movement or discomfort.
- Imaging shows structural changes such as displaced discs or joint degeneration.
- TMJ problems are significantly impacting quality of life, such as eating, speaking, or sleeping.
Every case is assessed individually. Risks, benefits, and alternatives are discussed thoroughly so patients can make an informed decision.
Dr van Mourik performs the following TMJ surgical procedures:
- Arthroscopy A minimally invasive procedure using a small camera inserted into the joint. Arthroscopy allows Dr van Mourik to visualise the joint directly, remove scar tissue, reposition the disc, and flush the joint. Recovery is faster than open joint surgery and it is suitable for a wide range of TMJ conditions.
- Open joint surgery (arthroplasty) For more complex cases involving severe disc damage, advanced arthritis, or joint degeneration, open joint surgery allows direct repair or reconstruction of the joint structures. This is performed under general anaesthetic at an accredited Sydney hospital.
- Total joint replacement In cases of severe joint destruction where the joint cannot be repaired, total TMJ replacement using a custom prosthesis restores function and eliminates pain. Dr van Mourik discusses all surgical options in detail at your consultation, along with expected outcomes and recovery.
Recovery After TMJ Surgery
Recovery varies depending on the procedure. Arthroscopy patients typically return to normal activities within one to two weeks. Open joint surgery requires a longer recovery period of four to six weeks. Dr van Mourik provides tailored post-operative instructions and follow-up care at both clinic locations.
Hospital Stay
- Arthroscopy or Arthrocentesis: Usually performed as day surgery.
- Complex Procedures (e.g. Joint Replacement): May require a 3–4 day hospital stay.
Pain Management
- Mild Procedures: Pain is generally managed with Nurofen® or Panadeine Forte®.
- Joint Replacement: IV pain relief is provided for the first 48 hours, followed by oral medication.
Time Off Work or School
- Arthroscopy, Arthrocentesis, or Arthrotomy: Allow approximately 3 days off.
- Joint Replacement: Plan for around 2 weeks off.
Diet and Wound Care
- Soft Diet: Continue for 3–4 weeks post-surgery.
- Stitches: Dissolving stitches usually disappear within 1–2 weeks.
Follow-Up Visits
- Regular reviews ensure proper healing and jaw function
Recovery After TMJ Botox Injections
Recovery after TMJ Botox injections is minimal. Most patients can return to normal activities immediately, though mild swelling or redness at the injection site is common.
Activity and Position
- Remain upright for 4 hours after treatment.
Avoid for 24 Hours
- Alcohol or exercise (including swimming).
- Nurofen® or other anti-inflammatory medication.
- Touching or rubbing the treated area.
- Applying makeup, sunscreen, or skincare to the site.
- Direct sunlight exposure.
Avoid for 1 Week
- Facial massages, waxing, or other beauty treatments.
Possible Temporary Effects
- Mild swelling, redness, bruising, or tenderness.
- Headache or fatigue lasting 1–2 days.
