Dental Problems that occur one after the other.....?

Could anyone provide me with some insight? I am a 41 yr old otherwise healthy woman. In Jan. 06, I had a root c and after that had one tooth start to go after another. By April (approx) I had 5-6 root cs, each tooth needed it. I also had some other symptoms during this time (I believe due to infection), such as palpitations, stomach discomfort, throbbing. Dental work all on left side of my mouth & so were phys. problems. I had MRIs, Xrays, bloodwork, EKG, upper GI, etc and all turned out negative. At the present I have already had 3 teeth extracted and another to be extracted today. (one had resorption and later another infected and w/ cellulitis). I have been in alot of pain. My dentist did send me out for consults & though an oral surgeon has seen me recently...I was told by some "didn't want to get involved". IDoes anyone have any guidance? Or if this oral surgeon can't help me, is there somewhere that's interested in helping in unusual cases like this? th-u
