TMJ
Causes of TMD

There are many causes for TMD such as:

  1. Unbalanced occlusion or 'Bad Bite'
  2. Stress (emotional or work/school related)
  3. Injury or trauma (this could have been an injury as obvious as a blow to the jaw with a fist or something as subtle as a whiplash injury with direct trauma to the head or jaw.)
  4. Teeth grinding or Bruxism

A 'Bad Bite' could be caused by any of the following:

  1. Missing teeth
  2. Crowded or 'crooked' teeth
  3. Worn down teeth
  4. Old crowns and bridges
  5. Unbalanced dentures

When teeth are missing, or out of alignment, it causes the jaw to shift positions and the muscles to work harder to chew, swallow, bite, etc. and eventually will cause: muscle spasms, tension and pain.

Muscle tension and misplaced TMJ could cause the TMJ disc to be pulled out of place which will result in pain, clicking and popping in the TMJ.

If the disc is displaced for a long time, the bones will start rubbing against each other and some damage will happen to the bone, this is called Osteoarthritis.

If there is inflammation in other joints or bones of the body, it is called Osteoarthritis (Arthritis) which may involve the jaw bone and the TMJ. Some damage to the bone may be evident on the x-rays.

TMD Symptoms

To help diagnose a TMJ disorder, you want to look for the following symptoms that are generally related to TMD.

  • Jaw Pain
  • Jaw Clicking
  • Limited Mouth Opening
  • Jaw Locking
  • Face Pain
  • Eye Pain
  • Ear Pain

If you are experiencing any of these symptoms, please call our office at (408) 340-6480 and we'll be happy to discuss them further and talk possible treatments that are available and would work best for you.

Jaw Tracking

This state-of-the-art jaw tracking system helps diagnose TMJ Dysfunction (TMD) by tracking the jaw movement.

Research shows that there are certain jaw movements which show very specific types of TMJ dysfunction. For example, limited opening and closing or locking, jaw opening deviations and deflections, and restricted side-to-side jaw movements. All of these indications are widely accepted and published criteria for diagnosing TMD.

Bite Splints

Bite splints (plates) are effective in relieving TMD symptoms.

A bite splint provides an acrylic platform to bite against. Some bite plates move the mandible to a new position.

Generally, splints are worn part-time and for most people night time seems to be the best time to wear them.

Electromyographic Analysis (EMG)

We use an Electromyographic Analysis (or EMG) to measure muscle activity on head and neck muscles both at rest and in function. This is done by placing computerized sensors on the skin allowing us to accurately monitor muscle activity.

Hyperactive muscles are common for patients experiencing pain symptoms associated with TMJ problems. Imbalances between right and left sides of the same sets of muscles are also typical. The EMG system is a safe and comfortable method do help detect such issues and getting to the root of a TMJ issue.

Headaches

If you suffer from frequent head or facial pain, an incorrect bite may be the cause due to constant cranial muscle strain. Headaches from dental stress are a type of muscle tension headache. A tension headache may be on one or both sides of your head and feels like a dull, non-throbbing ache that can usually be relieved by aspirin.

When you swallow, your upper and lower jaw muscles must hold your jaw firmly against the skull. Between swallowing over 2,000 times a day and a poorly aligned bite, the jaw muscles can overwork causing muscle strain which in turn leads to a headache. People who suffer from migraine pain and chronic headaches clench their jaws in a balanced, centered position. This causes extremely intense muscular contraction, but little strain on the jaw. Nighttime jaw clenching usually goes unnoticed but it sets the stage for migraine pain and chronic headache pain.

Joint Vibration Analysis (JVA)

The Joint Vibration Analysis (or JVA) has been accepted by the American Dental Association to help provide a fast, non-invasive method to accurately diagnose TMJ function and demonstrate the severity level of the problem.
