The spectre of mercury poisoning from dental fillings has made the leap from alternative medicine/tabloid fodder to official health concern, as the FDA now acknowledges the possible danger to children, unborn babies, and other sensitive populations. I doubt it's worth having fillings replaced (which I'm guessing could release more mercury than leaving them alone), but certainly a good idea to check with your dentist.
I'd much rather get my mercury from eating tuna and swordfish.
