Thank you very much Bryanna! I found the biological dentist through internet searches. I wasn't sure if I wanted to go there or not. Then I remembered an acquaintance who is extremely health conscience and holistic, so I asked her where she goes for dental work and it was the same place I found online. I have an appt Oct 15th. I appreciate your advice. What you said about negative blood tests and brewing diseases makes sense. I know, with all my being, that I am in the early stages of RA and I am also positive that my root canal is the culprit. I am leaning toward an implant right now. I can't wait to get this tooth pulled and be on the road to recovery.
