I'm not sure if anyone of experienced teeth grinding, clenching, and bruxism at night? It is horrible, I have neck and back pains due to this issue. I have checked out mouth guards from dentek and doctor's brand, but everyone swears by night guards from TotalGard. Has anyone purchased any products from TotalGard or know of the company? I've heard great things about their products and I wanted some feedback, before I purchased any night/mouth guards from them.
