Thanks for the info. Maybe I'll call. I'm skeptical in part about the dental/disease connection because my Dentist does not believe there is a connection and she is Natural, Mercury Free and outstanding. However, getting one if these scans can't hurt, and I could decide after it if I really felt there was a realistic chance of a cost;y, controversial dental procedure realistically helping with my immune system. WIth all of the work I've had done, nearly every tooth in my mouth could be suspect. And irony of ironies- they look perfect.
