I do think amalgams (those who have them) affect everyone at some point in their life. If they don't get you when you are still younger, you will get your share when you're older. I think people would live much longer without amalgams. With amalgams old people get infested with candida and all that stuff.
And nearly all old people have at least had one or more cavity in their teeth, so how many old people do not have amalgams in their teeth? (I think not many). Root canals may be even equally horrific to mercury, even if no mercury is used. And last but not least, the western diet fuels the candida, making things even worse.
