Dr. Mercola discusses the dangers of root canals here. If you read this article and are concerned about current fillings or need a root canal or other dental procedures ToxicTeeth.org will help get you in contact with a mercury free dentist or doctor. I actually had a root canal procedure done recently and I am seriously thinking about seeing a dentist that I found on this site. I think getting a second opinion and seeing what other options I have for that tooth couldn’t hurt- even after already getting a root canal. Yes, it would have been MUCH more helpful if I had known all of this important information pre-root canal but better late than never.
