OMD
Occluso-Muscular Disorder- probably 70 to 80 percent of people who have jaw pain, or "TMJ", are better classified under this heading. OMD means a diagnosis of muscle pain caused by a malocclusion, or bad bite. Having your mouth close with your jaw joints out of alignment requires constant posturing of the jaw muscles, and those muscles can become chronically spastic, like an eternal "charley horse". Treatment for this problem is directed at relaxing the muscles, and then correcting the occlusion if necessary.
