Can you provide a list of the more experienced,(successful) clinics in
North America that are well equipped with both Conventional medical
doctors as well as Naturopathic doctors and dentists that work as a
group to address metal toxic poisoning associated with amalgam
fillings and/or osteonecrosis?

I don't think any highly rated organization would touch this. The
mainstream dental organizations insist that negligible mercury is
absorbed from amalgum fillings. Generally dentists don't recommend
replacing sevicable amalgum fillings, but most will replace them is
you insist, and some dentists no longer instal amalgum fillimgs. It is
one of the many topics where the truth is elusive. According to one
sourse, amalgum of silver and mercury (if theoughly mixed) truly does
release negligible mercury, but "improved" amalgum has several pecent
copper added to make the filling harder, but this does allow small
amounts of mercury to enter your system. Seems logical, but it may all
be technobable. A few people have improved health shortly after having
amalgum fillings removed, but there is some evidence that mercury
posoning was not the cause of their poor health.   Neil
