The American Dental Association (ADA) has asserted
that dental amalgam is safe since its foundation
in 1859. In its advisory opinion to Rule 5.A. of
the ADA Code of Ethics, it has also held that,
"the removal of amalgam restorations from the
non-allergic patient for the alleged purpose of
removing toxic substances from the body,
when such treatment is performed solely at the
recommendation or suggestion of the dentist,
is improper and unethical".
According to the Boston College Law School study,
"A dentist who is found guilty of violating the
ADA Code of Ethics can be sentenced, censured,
suspended, or expelled from the ADA" and the
"ADA forbids its dentists from suggesting
mercury removal under threat of license suspension".
