If you are looking for excellent detailed information about the effects of amalgam fillings, I recommend a book by Hal Huggins called, "It's All In Your Head", by Hal Huggins.<P>When I first learned that I had mercury in my mouth (thanks to amalgam fillings), I located and read this book in 2 days... cover to cover.<P>It'll change your view of dentistry and help make you become an informed patient.<P>Herb Allure distributes this book. Contact Herb Allure or your local bookstore for more information.<P>------------------<BR>Russ Tanner<BR>of Herb Allure
