Patients with temporomandibular joint disorder (TMD or TMJ) may have jaws that “lock” or make popping and clicking noises. They may have facial pain and chronic headaches, or numbness. Dr. Brown helps position the ball of your jaw joint in its correct position to relieve these symptoms. Treatment may include a custom-fit splint, a thin plastic mouthpiece that is fit over your upper or lower teeth to help gently reposition your jaw.
