My story is similar I had two root canals extracted all the mercury removed and still felt horrible it was because the holistic dentist botched this job it took me 18 month to figure out the cause. He place a bone graft that my body was rejecting... I was allergic to the bone graft and he had place the bone graft , over necrotic jaw bone. I found great a cavitation specialist to clean out every extraction site, He opened the site and said this bone graft looks really odd, and then it was oily looking it was pus, an brewing infection and he took it out and underneath of that was bone infection. Bone infections are a medical emergency and seriously need to be dealt with. It is better to see an expert . The other piece here is that root canal leak virulent strains such as strep staph etc,, and effect other parts of the body usually the heart , lungs liver etc.. Getting the root canal extracted is not enough you must see a cavitation expert and get lined up with someone that can get you on broad spectrum NATURAL Antibiotics you do not need the side effects from super strong Antibiotics the RISKS are to great when you are already comprimised also get on a high quality probiotic Find an alternative medicine doctor to work with they will bring you back to full health in a gentle natural way, .
