with that many Amalgam fillings, the body must be laden with mercury. i think its a detox effect more than the fillings. and the decay is from diet, not prevention.
do you use supplements with titanium dioxide? have you eliminated fluoride from your environment? there is a lot more to it than just amalgams, but getting them out is essential. your problems, in all likelyhood, started long ago and continue to be exacerbated from many sources, not the least of which is the body's inability to deal with it all from the deadly neurotoxin MERCURY!!!
