Botox is commonly known as a solution for cosmetic concerns, because of how it can effectively smooth wrinkles or restore firmness to sagging skin. However, there are many other uses for botox. Botox is also used to treat TMJ symptoms as well as the symptoms of bruxism. Botox is used to relax the muscles of the jaw and alleviate the clenching or tension in the jaw area which is often characteristic of these conditions. This is because botox works by "blocking" signals to the muscle they are affecting, which prevents grinding, clenching, or tension. It can also help with symptoms of migraines associated with tension in the TMJ muscles.
