i have been searching for a cause for my chronic fatigue and have come across a lot of information stating root canals can lead to various seemingly unrelated disease such as heart disease and cancer. i have just ordered " root canal Cover-Up", by Dr. George Meinig.

Apparently Dr. George Meinig was at the forefront of root canal development and spent many years performing and teaching others how to perform root canal. Then he discovered the research done by Dr Weston price who was against root canals. He was so convinced by Dr Weston's evidence he changed his stance and wrote the above book. I have just ordered it on amazon and would recommend you do the same.

Actually there are many more books on amazon relating to the same subject. I was amazed as I had never heard of this before.

I currently have 2 root canals and from all the evidence I have read so far, I'm pretty sure I will be having them removed soon. My health is more important than a tooth or 2. Also it seems having any metal in your mouth is bad, especially if you have at least 2 different types as along with your saliva to act as a conductor, you basically create a battery in your mouth that can interfere with your body and brains natural currents. I had permanent metal retainers top and bottom, but I had them both removed yesterday and I'd swear I notice a difference and feel a little better already.

Even today I was talking to a friend about the root canals and he started telling me how he had a root canal done, he had some problems with it, pain, swelling, but he had also developed eczema at the same time. He had the root canal removed and his eczema cleared up in a matter of days.

My advice would be to search for a holistic or biological dentist who will be more open to your concerns, and to seriously consider loosing a tooth as you may get your health back.
