TMJ and Jaw Pain Causes and Treatment

If you think you may be suffering from tooth grinding or TMJ disorder, don’t hesitate to contact Dr. Patrick Lawrence and Dr. Shanup Gundecha of Family & Cosmetic Dentistry in Cary, NC.

Signs and symptoms of TMJ disorders may include:

  • Pain or tenderness of your jaw
  • Pain in one or both of the temporomandibular joints
  • Aching pain in and around your ear
  • Difficulty chewing or pain while chewing
  • Aching facial pain
  • Locking of the joint, making it difficult to open or close your mouth

TMJ disorders can also cause a clicking sound or grating sensation when you open your mouth or chew. But if there’s no pain or limitation of movement associated with your jaw clicking, you probably don’t need treatment for a TMJ disorder.

When to see a doctor

Seek medical attention if you have persistent pain or tenderness in your jaw, or if you can’t open or close your jaw completely. Your doctor, your dentist or a TMJ specialist can discuss possible causes and treatments of your problem.


The temporomandibular joint (TMJ) combines a hinge action with sliding motions. The parts of the bones that interact in the joint are covered with cartilage and are separated by a small shock-absorbing disk, which normally keeps the movement smooth.

Painful TMJ disorders can occur if:

  • The disk erodes or moves out of its proper alignment
  • The joint’s cartilage is damaged by arthritis
  • The joint is damaged by a blow or other impact
  • In many cases, however, the cause of TMJ disorders isn’t clear.
  • Risk factors
  • Factors that increase the risk of developing TMJ disorders include:
  • Various types of arthritis, such as rheumatoid arthritis and osteoarthritis
  • Jaw injury
  • Long-term (chronic) grinding or clenching of teeth
  • Certain connective tissue diseases that cause problems which may affect the temporomandibular joint

Tooth grinding, also known as bruxism, is an extremely common dental problem that should not be taken lightly. Oftentimes patients who grind their teeth do it while they sleep, so they may not be aware of just how much damage the clenching and grinding of their teeth can cause.

The experienced dental professionals at our Cary dental office will conduct a dental exam and take digital x-rays if necessary to determine if teeth grinding is seriously affecting your dental health. For those who grind their teeth in their sleep, our Cary dentists can fit your mouth with a comfortable mouth guard to help prevent your teeth from wearing on each other. A small NTI appliance is also available.
