What kind of metal? I have stainless steel (retainer) in my mouth with no problems, but the mercury fillings were a huge issue.

i don't know, but i better ask. he did say it was not mercury tho.
it's a three tooth bridge that needs to be replaced. i chipped off the porcelin on the back tooth and broke the metal underneath which was the tooth cap i think. plus i have a cavity which needs filling. AND one the teeth had a root canal done many years ago.
arghhh.

I would go to a mercury free dentist. Someone who knows all the materials available and does it all the time. Also, a mercury free dentist who knows how to properly remove amalgams if that is going to be part of your procedure.

Mercury exposure as a model for deviation of cytokine responses in experimental Lyme arthritis: HgCl(2) treatment decreases T helper cell type 1-like responses and arthritis severity but delays eradication of Borrelia burgdorferi in C3H/HeN mice.

Lyme borreliosis is a complex infection, where some individuals develop so-called 'chronic borreliosis'. The pathogenetic mechanisms are unknown, but the type of immune response is probably important for healing. A strong T helper cell type 1 (Th1)-like response has been suggested as crucial for eradication of Borrelia and for avoiding development of chronic disease.
Many studies aimed at altering the Th1/Th2 balance in Lyme arthritis employed mice deficient in cytokine genes, but the outcome has not been clear-cut, due possibly to the high redundancy of cytokines.
This study aimed at studying the importance of the Th1/Th2 balance in murine Borrelia arthritis by using the Th2-deviating effect of subtoxic doses of inorganic mercury. Ninety-eight C3H/HeN mice were divided into four groups: Borrelia-infected (Bb), Borrelia-infected exposed to HgCl(2) (BbHg), controls exposed to HgCl(2) alone and normal controls. Mice were killed on days 3, 16, 44 and 65 post-Borrelia inoculation.
Arthritis severity was evaluated by histology, spirochaetal load determined by Borrelia culture, IgG2a- and IgE-levels analysed by enzyme-linked immunosorbemt assay (ELISA) and cytokine-secreting cells detected by enzyme-linked immunospot (ELISPOT).
BbHg mice showed less severe histological arthritis, but delayed eradication of spirochaetes compared to Bb mice, associated with increased levels of IgE (Th2-induced) and decreased levels of IgG2a (Th1-induced), consistent with a Th2-deviation. Both the numbers of Th1 and Th2 cytokine-secreting cells were reduced in BbHg mice, possibly explained by the fact that numbers of cytokine-secreting cells do not correlate with cytokine concentration.
In conclusion, this study supports the hypothesis that a Th1-like response is required for optimal eradication of Borrelia.
