What is TMJ problem and how is it caused?
The exact cause of the disorder is unknown. Some factors are related to an improper bite, injury, arthritis, severe stress, or a combination of factors. Clenching or grinding teeth, a condition called bruxism, may develop from stress or as part of a sleep disorder. This can tire muscles and create painful spasms, causing even more pain. Repeated muscle problems may affect the joints, resulting in tissue damage, muscle tenderness, and more spasm, perpetuating a cycle of pain.
