Believe me, you don't have to convince me that dentists are evil. If my dentist had his way I would already have a crown and 4 more fillings that I am pretty sure I don't need. The only reason I want to keep the tooth is to keep him away from it. He gave me the root canal in the first place.
I could be wrong, but I believed that Miracle-Mineral-Supplement would kill pathogens in the body, and therefore, "fix" the problems with the root canal. Maybe that was wishful thinking. but you can't blame a girl for trying ;)
