Botox can be used to treat temporomandibular joint (TMJ) disorder, a condition that causes pain and dysfunction in the jaw joint and muscles. Botox can be injected into the muscles that control jaw movement to reduce muscle tension and pain.   Botox can be used to relieve a number of symptoms associated with temporomandibular joint (TMJ) disorder, including:   • Pain - Botox can be injected into the jaw muscles to reduce muscle tension and pain. • Bruxism - Botox can also be used to relax the muscles that control jaw movement, which can help to reduce teeth grinding (bruxism) and jaw clenching. • Limited jaw movement - Botox can be used to relax the muscles that control jaw movement, which can help to increase the range of motion in the jaw. • Muscle stiffness - Botox can help to reduce muscle stiffness and spasms, making it easier to open and close the jaw. • Locking of the jaw - Botox can help to reduce the locking of the jaw by relaxing the muscles that cause it.   Botox is not a permanent cure for TMJ disorder, and it should be used in conjunction with other therapies to manage symptoms. Some people may find that they need to receive Botox injections more frequently than others. This may depend on the severity of symptoms, the underlying cause of the disorder, and the individual's response to the treatment.
