Temopromandibular disorder can develop for many reasons. You might clench or grind your teeth, tightening your jaw muscles and stressing your temporomandibular joint. Or you may have a damaged jaw joint due to injury or disease. Whatever the cause, the results may include a misaligned bite, pain, clicking or grating noises when you open your mouth, or trouble opening your mouth wide.

Temporomandibular disorders are treated with upper or upper and lower removable appliances.
