Both my two front upper teeth have been root-canal filled (rcf) more
than twenty years ago.  According to Dr Weston Price early last
century,  rcf teeth can cause health problems.  I have chronic renal
failure and have been on kidney dialyses for nearly two years.

I understand from Dr Price's and later Dr George Meining's research
http://www.optimalhealthdentistry.com/rootcanals.html that the health
improves when the rcf teeth are removed.

My question. Is there is any current research into this theory as I
wish to remove these rcf teeth and see if my health improves.  I would
prefer to do this as part of a research study 1.  to help others and, 
2.  to ease the financial burden.
It would be preferable for me that the research be in Sydney, Australia.

If there is no current research, then a dentist in Sydney who wishes
to carry out the work at a reasonable price

I am a dentist..I have worked and researched the dental profession for
over ten years

Never have I come across a paper that correlates RCT's to kidney problems. 

Also from what I know about biology and biomaterials (I have studied
both) the plausibility of this would be pretty much nil.

Keep your teeth
