TMJ Disorders

The TMJ (temporomandibular joint) ranks among the body's most frequently used joints, making it susceptible to a variety of complications. Physiotherapy offers an effective treatment approach for the many conditions that stem from TMJ dysfunction.

Treatment typically uses techniques designed to enhance jaw movement — including massage, targeted stretching and coordination exercises for the muscles around the TMJ, and joint-capsule stretching. Physiotherapists have specialised knowledge of musculature and muscle physiology, positioning them well to treat TMJ disorders. The aims are to relax tightened muscles, release scar tissue, correct postural issues, and restore joint mobility and stability.

Types of physiotherapy for TMJ disorders

Physical exercises

Exercises designed to strengthen the muscles around the TMJ and improve the mouth's flexibility and range of motion.

Temperature therapy

Both heat and cold applications help — heat improves circulation while ice reduces pain and swelling.

Massage and myofascial release

Helpful in relieving general tension of the jaw muscles.

Posture correction

Improving posture addresses pain and tension radiating to the neck, shoulders and back.

Low-level laser and ultrasound therapy

Laser therapy uses light-waves for anti-inflammatory effects and tissue repair. Ultrasound therapy employs sound-waves to reduce inflammation and break down scar tissue.

Dry needling and acupuncture

A fine needle is inserted into the skin and slightly into the underlying muscle at trigger points to release tension and increase blood circulation.

What is the TMJ and how does it work?

The temporomandibular joint comprises two joints connecting the lower jawbone to the skull's temporal bone. They act like sliding hinges, combining sliding motions with a hinge action. Cartilage lines the interacting bones to prevent friction, while a small disk absorbs shock. These joints enable jaw movement up and down, side to side, and forward and backward — functions essential for talking, chewing, swallowing and yawning.

Signs and symptoms of TMJ disorders

• Discomfort in the jaw, often worst in the early morning and/or late afternoon
• Ear pain or ringing in the ears
• Headaches and dizziness
• Facial pain or pain behind the eyes
• Pain spreading to the shoulder, neck or back
• Difficulty or pain when chewing
• Lockjaw, clicking, popping or grating sounds
• Tooth sensitivity, or numbness and tingling in the fingers
• Misalignment of the teeth

Causes and risk factors

Exact causes often remain unclear and may stem from several factors, including genetics. Common causes include bruxism (jaw clenching and teeth grinding), cartilage damage from arthritis or degenerative disease, trauma from a forceful impact, and disk erosion or misalignment.

Diagnosis and treatment

Your physiotherapist will assess your symptoms by listening to the jaw as you open and close your mouth, observing range of motion, and applying gentle pressure to identify painful areas. Where the initial examination is inconclusive, imaging studies such as X-rays, CT scans, MRI or arthroscopy may be recommended. A personalised programme is then developed based on the suspected cause, enabling you to regain normal jaw function while addressing associated pain.
