TMJ dysfunction refers to a variety of conditions that affect the temporomandibular joint (TMJ), which connects the jawbone to the skull. The TMJ is responsible for facilitating movements such as opening and closing the mouth, chewing, and speaking. Dysfunction of the TMJ can cause pain and discomfort in the jaw, face, neck, and head.

Common symptoms of TMJ dysfunction include:

  • Pain or tenderness in the jaw joint
  • A clicking, popping, or grinding sound when opening or closing the mouth
  • Difficulty opening the mouth wide
  • Headaches or ear pain
  • Jaw muscle stiffness or soreness
  • Toothaches or sensitivity
  • Locking of the jaw joint

The exact cause of TMJ dysfunction is not always clear, but it can result from several factors such as:

  • Injury to the jaw or TMJ
  • Bruxism (teeth grinding or clenching)
  • Arthritis in the TMJ
  • Stress or anxiety, leading to jaw clenching or teeth grinding
  • Misalignment of the teeth or jaw

The treatment for TMJ dysfunction may include various approaches such as pain medications, splints or mouthguards, physical therapy, and in severe cases, surgery. The role of a physiotherapist in treating TMJ dysfunction may include exercises to improve jaw mobility, manual techniques to reduce muscle tension, and modalities such as ultrasound or heat therapy to relieve pain and inflammation. A chiropractor may also use manual therapies to alleviate joint restrictions and improve TMJ function.


The symptoms of TMJ dysfunction can vary from person to person and can range from mild to severe. Some common symptoms of TMJ dysfunction include:

  1. Pain or tenderness in the jaw joint
  2. Pain in or around the ear
  3. Difficulty or discomfort while chewing
  4. A clicking or popping sound when opening or closing the mouth
  5. Limited range of motion in the jaw
  6. Headaches
  7. Neck or shoulder pain
  8. A feeling of tiredness in the face
  9. Swelling on one or both sides of the face

It’s important to note that these symptoms can also be caused by other conditions, so it’s important to see a healthcare provider for an accurate diagnosis.


The exact causes of TMJ dysfunction are not fully understood, but there are several factors that can contribute to its development. Some of the most common causes include:

  1. Jaw injuries: Trauma to the jaw joint or muscles can cause damage and lead to TMJ dysfunction.
  2. Teeth grinding or clenching: This puts excessive pressure on the jaw joint and muscles, leading to irritation and inflammation.
  3. Arthritis: Osteoarthritis or rheumatoid arthritis can cause damage to the joint cartilage and lead to TMJ dysfunction.
  4. Stress: Emotional or physical stress can cause muscle tension in the face, neck, and jaw, leading to TMJ dysfunction.
  5. Malocclusion: A misalignment of the teeth or bite can cause an uneven distribution of pressure on the jaw joint and lead to TMJ dysfunction.
  6. Connective tissue disorders: Certain medical conditions such as Ehlers-Danlos syndrome or Marfan syndrome can cause laxity in the ligaments and muscles of the jaw, leading to TMJ dysfunction.
  7. Oral habits: Certain habits such as nail biting, chewing gum, or biting pencils can put excessive pressure on the jaw joint and muscles, leading to TMJ dysfunction.

It’s important to note that sometimes the exact cause of TMJ dysfunction is not known, and it may develop due to a combination of factors.


Physiotherapists can play an important role in the management of TMJ dysfunction. They may use a variety of techniques, including:

  1. Jaw exercises: Physiotherapists can prescribe exercises to help strengthen the muscles around the jaw joint and improve jaw mobility.
  2. Manual therapy: Techniques such as massage, stretching, and joint mobilization may be used to improve joint mobility and reduce muscle tension.
  3. Heat or cold therapy: Applying heat or cold to the affected area can help reduce pain and swelling.
  4. Electrical stimulation: This involves using low-level electrical currents to stimulate the muscles and reduce pain.
  5. Education: Physiotherapists can educate patients on proper posture, chewing techniques, and other lifestyle modifications that can help reduce symptoms.

Overall, the goal of physiotherapy in TMJ dysfunction is to reduce pain and improve function, allowing patients to perform their daily activities with greater ease and comfort.


Chiropractors can also play a role in the treatment of TMJ dysfunction, particularly if the condition is caused by issues with the alignment of the jaw or neck. Chiropractors may use manual techniques such as adjustments, mobilizations, and soft tissue therapies to help realign the jaw or neck and relieve tension and pain in the TMJ area. They may also recommend exercises and stretches to help improve range of motion and reduce stiffness in the jaw. However, it is important to note that the effectiveness of chiropractic care for TMJ dysfunction may vary depending on the individual case, and it is always best to consult with a healthcare professional before seeking any form of treatment.


Physiotherapy can provide several benefits for individuals with TMJ dysfunction, including:

  1. Pain relief: Physiotherapists can use techniques such as manual therapy, acupuncture, and dry needling to relieve pain in the jaw, neck, and head regions.
  2. Improved jaw function: Physiotherapy can help improve jaw mobility, allowing individuals to open their mouths wider and more comfortably.
  3. Strengthening exercises: Physiotherapists can design specific exercises to strengthen the muscles around the jaw and neck, which can help reduce the risk of future TMJ dysfunction.
  4. Posture correction: Poor posture can contribute to TMJ dysfunction. Physiotherapists can provide guidance on how to improve posture and reduce stress on the jaw.
  5. Education and self-management: Physiotherapists can educate individuals on how to manage their symptoms and prevent further complications of TMJ dysfunction through self-care techniques such as relaxation exercises, stress management, and jaw stretching.

Overall, physiotherapy can be an effective treatment option for individuals with TMJ dysfunction, helping to alleviate pain, improve jaw function, and prevent future episodes of dysfunction.
