I have probably most of my up and down back teeth filled with silver fillings, my mouth has a metally taste to it, should I be worried????????

Your "silver" fillings are actually composed of approximately 50 percent mercury. This mercury continually leaks and is accumulated in the body. For some people, this has been a problem. It was a problem for me, and after I had these poisons removed, I've recovered significantly.

Should you be worried? I would say that you should be concerned, rather than worry. I would read up about it first before reacting. You can find lots of information about this on the internet. Not everyone in the medical community understands this.

I felt it is very important that I let you and others know, that these are not silver fillings, in the way that most of us think. Mercury is the metal of highest composition in a typical dental amalgam. Silver is generally second, in terms of metal composition.
