Re your article on sarcoidosis (WDDTY vol 13 no 2, Q&A), my experience is that there is a two-way connection between teeth and various organs and systems of the body. The root-canal theory assumes a one-way connection - poisoning from a root canal to an organ - but I believe that imbalances in the rest of the body can have an effect on tooth health. I suspect that GS's tooth problem originated elsewhere and the root-canal filling has exacerbated the problem.
As a craniosacral therapist, I 'unwind' the tooth and feel where it is connected to. As there often appears (to my senses) to be a meridian connection, an acupuncturist would probably also be helpful. Direct tooth unwinding can also provide the finishing touches to clearing abscesses. - Andrew Cook, via e-mail
