I don't know if I can help you as I am not an expert in this area of root canal infection and extraction. But, I have read a lot about Dr. Price's research on the toxicity of root canals and it does appear to hold some weight in my opinion. But, then again I have been wrong in the past. What I am curious to know is, why didn't the dentist clean out the infection after extraction. From what I understand is that the biological dentists are supposed to be highly trained in this area. He/she must have been a bio-dentist if they done the kinesiology test. Also, what is your opinion of the kinesiology test? I believe that it is a good income generator for the dentist. I had this test done as well and basically my feeling was that I paid the dentist money to push on my arm for 15 minutes. I find it difficult to believe that someone can put a pair of sunglasses on your chest, stick a finger on your tooth, push on your arm and say "you have an infection"!! I'm definitly sceptical!
I'm debating a decision on root canal extraction at this time.
