And I suggest that you read a few books on the subject of amalgams. A good one to start with is written by Hal Huggins. Another book is titled "Tooth Truth" author is Frank J. Jerome. Both of these people are former dentists.
Of course we ALL realize the Amalgam fillings are "totally safe"...as reported by the American Dental ASSociation.......they make LOTS of money off unsuspecting people by putting poisonous metals in mouths every day.
You say how biased is your source? That is the question I ask you .....how biased is YOUR source?
The love on money is the root of all evil....have you heard of that one ?
Most people with Dr. in front of their name is all about $$$$.
