There is a new and interesting treatment for treating TMJ and other causes of jaw stiffness and pain. These treatments are experimental currently but the research shows the treatment could be beneficial. The injection of Botox into the facial muscles around the jaw can relax the muscle and can reduce TMJ pain and even reduce headaches in people who grind their teeth. No other areas of the face are affected by the injections and the pain is brief and minimal. The procedure is also quick, lasting usually 10-30 minutes depending on the severity. After your injection you will start to feel relief nearly immediately, but how long will it last?
