Ah, ok. Yeah, those things just sounded so familiar to me. That is the reason for your health problems. The symptoms are from both the mercury and root canals. My body hurt so bad, I could not lay in bed unless I was sleeping, otherwise the pain was nearly unbearable. Yes, Biologic Dentists remove root canals. The crowns, if they are porcelain over metal and not gold (over over the top of a mercury filling), need replaced. If you need help finding a Dentist, you can email me or call me. You should feel at least 90% better (or more) after it is out and you chelate.
