My dentist says I need a crown for one of my bottom teeth and he has
explained that you need a strong base under it. He says the best base is
amalgum because it is strong enough to provide long term support for the
porcelain or gold crown. Some people have told me to avoid amalgum like the
plague because on a daily basis, deadly mercury is released into the body.

I have read an article by Dr. Gerald H. Smith that says "It is estimated
that 70% of all medical illnesses are directly or indirectly caused by human
intervention in the dental structures (teeth and jawbones)." He also says
that dental amalgum fillings slowly leak mercury, tin, silver, copper and
sometimes nickel, see

I have also read that toxic bisphenol A (BPA) may be released from certain
"white" / plastic dental sealants.

So is there a strong material that doesn't release toxic substances into the
body that may be used as a base for a crown? Or would I be better to just
have the tooth removed? Thanks for your input.
