Let's
not forget the big picture here. Mercury poisoning from any source is
egregious, especially when it is completely unnecessary. Some may say
mercury in the air from coal burning is a necessary economic evil.
However, because there exists a tradition of putting neurotoxic mercury
into people's mouths does not mean that it should continue. On the
contrary, with new safer fillings like porcelains and composites there
is NO reason to expose anyone in the process of filling a tooth with
toxic mercury, much less the end user, where the filling will leak into
the persons body every second of every day, 365 days a year.
