Additional symptoms of TMD include headaches, tinnitus, dizziness, ear pain.
Women are least three times more likely to seek care for the disorder.
The cost of health care for TMD patients is twice that of unaffected individuals. The consequences of TMD include decreases in ability to chew foods, difficulty opening wide, lost days from work, interference with leisure activities, irritability and moodiness, depression, and reduction in the general quality of life. Unfortunately, there is considerably less known about the etiology of the disorder. One set of theories has proposed that occlusal imbalance between teeth accounts for the disorder. To date, there is no good evidence to support this perspective.
