Your temporomandibular joint, or TMJ, connects your jawbone to your skull. It is present on each side of your head and allows for movement during chewing or speaking. While many people refer to problems with this joint as “TMJ,” this term actually just refers to the name of the joint itself.

Problems associated with the temporomandibular joint can be called temporomandibular joint dysfunction (TMD). This broad term describes various conditions that cause pain and dysfunction in the joints or muscles of the jaw.

Temporomandibular joint dysfunction encompasses various medical conditions affecting the jaw, joints, and surrounding muscles. Some medical conditions related to TMJ conditions include:

• Bruxism:
  • A condition characterized by teeth grinding or clenching, which can lead to TMJ pain and discomfort.
• Arthritis: 
  • Inflammatory conditions such as rheumatoid arthritis or osteoarthritis can affect the TMJ.
• Jaw Dislocation: 
  • Occurs when the jaw joint becomes displaced, causing pain and limited movement.
• Myofascial Pain Syndrome: 
  • A chronic disorder that affects the muscles and connective tissues in the jaw area.
• Trauma or Injury: 
  • Direct trauma to the joints of the jaw or surrounding structures can result in TMJ-related symptoms.

Experience with temporomandibular joint dysfunction can vary from person to person. For some, it can simply be a temporary issue with mild symptoms. For others, it can be a chronic condition; although this is typically less common. Some symptoms of TMJ dysfunction may include the following:

• Jaw pain or tenderness
• Difficulty or pain while chewing
• Clicking or popping sounds when opening or closing the mouth
• Locking of the jaw
• Headaches/Migraines
• Ear pain or ringing in the ears (tinnitus)
• Neck and shoulder pain
• Facial pain or swelling
• Difficulty opening the mouth fully
• Changes in the alignment of the teeth

Temporomandibular joint dysfunction is thought to be caused by various factors, although identifying one exact cause can be difficult. In many cases, an individual can have multiple causes that may contribute to their symptoms.

There are many components, such as hereditary aspects or lifestyle habits, that can contribute to TMJ dysfunction. Occasionally, there may even be no apparent cause for TMJ issues. Some possible factors that lead to TMJ may include:

• Jaw injury or trauma
• Teeth grinding or clenching
• Arthritis in the jaw joint
• Misalignment of the jaw or teeth
• Stress or anxiety leading to jaw-clenching
• Poor posture
• Genetics
• Dental procedures or surgeries
• Connective tissue disorders

Your physical therapist or other providers can diagnose temporomandibular joint dysfunction through a comprehensive evaluation, which may include the following:

 

• Medical History Assessment: 
  • Your physical therapist will ask about your symptoms, medical history, and any factors that may be contributing to your jaw pain or dysfunction.
• Physical examination: 
  • Your jaw movement, muscle strength, and joint function will be examined. They may also check for tenderness, clicking or popping sounds, and signs of misalignment.
• Range of motion tests: 
  • Your physical therapist may measure the range of motion of your jaw to determine any limitations or abnormalities.
• Palpation: 
  • Your therapist will need to gently palpate the joints of your jaw and the surrounding muscles to identify areas of tenderness or tightness. 
• Functional tests: 
  • Functional tests may be performed to assess how your jaw functions during activities such as chewing, speaking, and yawning.

After diagnosis, your physical therapist will develop a personalized treatment plan to address your specific symptoms and improve overall jaw function.

Please note that seeking guidance from a qualified healthcare professional for an accurate diagnosis and appropriate management of temporomandibular joint dysfunction is important.

There are different forms of treatment suitable for TMJ, but may vary based on your individual needs. Physical therapy can be ideal for improving the strength and function of the jaw. They may also utilize pain-relieving treatments if necessary.

Some specific physical therapy treatments your provider may use for TMJ can include:

• Dry Needling
• Cupping
• Manual Therapy 
• Spinal Manipulation 
• Electrical Muscle Stimulation
• Tissue Scraping 
• Exercise Prescription
• Behavioral Modifications
• Therapeutic Modalities
• Neuromuscular Re-education
• Biofeedback (part of neuromuscular)
• Therapeutic Activity 

Depending on your symptoms and lifestyle habits, some recommendations may be suggested to prevent future temporomandibular joint dysfunction. If you play sports, clench your jaw often, or grind your teeth in your sleep, usage of a suitable mouth guard may be recommended.
