Minor Problems Might Turn Out To Be TMJ/TMD

 

Temporomandibular joint disorders are problems affecting the jaw joint, usually pain or reduced movement of the joint. There are various causes but mostly it is not a serious condition, and often improves with simple treatments.

The temporomandibular joint (TMJ) is the hinge joint that connects the lower jaw (mandible) to the temporal bone of the skull, which is immediately in front of the ear on each side of your head. The joints are flexible, allowing the jaw to move smoothly up and down and side to side and enabling you to talk, chew, and yawn. Muscles attached to and surrounding the jaw joint control the position and movement of the jaw.

 

What are TMJ disorders, and what are causes of TMJ disorders?

TMJ disorders are a group of complex problems of the jaw joint. TMJ disorders are also sometimes referred to as myofascial pain dysfunction and Costen’s syndrome. Because muscles and joints work together, a problem with either one can lead to stiffness, headaches, ear pain, bite problems (malocclusion), clicking sounds, or locked jaws. The following are behaviors or conditions that can lead to TMJ disorders.

  • Teeth grinding and teeth clenching (bruxism) increase the wear on the cartilage lining of the TMJ. Those who grind or clench their teeth may be unaware of this behavior unless they are told by someone observing this pattern while sleeping or by a dental professional noticing telltale signs of wear and tear on the teeth. Many patients awaken in the morning with jaw or ear pain.
  • Habitual gum chewing or fingernail biting
  • Dental problems and misalignment of the teeth (malocclusion). Patients may complain that it is difficult to find a comfortable bite or that the way their teeth fit together has changed. Chewing on only one side of the jaw can lead to or be a result of TMJ problems.
  • Trauma to the jaws: Previous fractures in the jaw or facial bones can lead to TMJ disorders.
  • Stress frequently leads to unreleased nervous energy. It is very common for people under stress to release this nervous energy by either consciously or unconsciously grinding and clenching their teeth.
  • Occupational tasks or habits such as holding the telephone between the head and shoulder may contribute to TMJ disorders.

 

Symptoms associated with TMJ disorders may be:

  • Blinking
  • Biting or chewing difficulty or discomfort
  • Clicking, popping, or grating sound when opening or closing the mouth
  • Dull, aching pain in the face
  • Earache (particularly in the morning)
  • Headache (particularly in the morning)
  • Hearing loss
  • Migraine (particularly in the morning)
  • Jaw pain or tenderness of the jaw
  • Reduced ability to open or close the mouth
  • Tinnitus
  • Neck and shoulder pain
  • Dizziness

Because many other conditions can cause similar symptoms to TMD including a toothache, sinus problems, arthritis, or gum disease, your dentist will conduct a careful patient history and physical examination to determine the cause of your symptoms.
