Treatment of TMJ disorder in dental science also typically focuses on correcting malocclusion, or an incorrect bite. In some cases, this may involve the use of orthodontic appliances to correct abnormal tooth alignment. Medications, such as nonsteroidal anti-inflammatory drugs (NSAIDs), are often prescribed to reduce inflammation and pain in the temporomandibular joint as well as other affected areas. Oral splints, which are designed to reduce tension in the joint, are often recommended in order to help relieve pain. In some cases, surgery may be required to treat persistent problems in the joint. Physical therapy, exercise, and educational instruction about minimizing dental trauma and avoiding certain activities that may precipitate a flare-up are often included in the treatment of TMJ disorder. There is evidence that cognitive-behavioral therapy (CBT), which involves the patient learning coping strategies, may be beneficial in treating this disorder. In many cases, an interdisciplinary approach to TMJ treatment is most effective. For instance, dentists may work in collaboration with physical therapists, occupational therapists, and speech-language pathologists to improve symptoms such as jaw pain and stiffness, tinnitus, and difficulty speaking or opening the jaw. Treatment of TMJ disorder in dental science is highly individualized, as the exact cause of the condition may vary from one person to another.
