Botox allows the muscle to relax and perform their regular function. Patients suffering from pain caused by myofascial pain and temporo-Mandibular Joint Dysfunction Syndrome can have great benefits using Botox. If left untreated, excessive grinding and clenching can result in worn and broken teeth and costly treatment for repairs. Botox can give bruising for a few days and some people can have a mild reaction to it. Dr. Oestervemb will discuss benefits and risks in detail at your consultation visit.
