The FDA says mercury is dangerous (but they still promote vaccination):

My local dentist says it is not.

The American Dental Association doesn't dare commit.

In 2009, Twin Falls City spent $50,000 to clean up two teaspoon's worth of mercury spilled on the street.  http://magicvalley.com/news/local/article_a0a8cab6-20f9-5aca-adbb-dc0fa243bf45.html

Do these people ever get together?

In 1996, Charlie Brown, who founded the Consumers for Dental Choice said:
      At the start of our movement, we confronted an iron triangle; three major forces: The American Dental Association that profits from a system of consumer ignorance; The Food and Drug Administration that sits in the hip pocket of the American Dental Association… and the state dental boards, who were the enforcers who told dentists:  You have to be silent.
     The American Dental Association had a gag rule and said,  Don't say the M word.  Don't tell people about the mercury; don't say that it's a toxin, or there will be consequences.
    The consequences were the state dental boards pulling licenses of dentists all through the 1990's and threatening to pull the licenses of many more.

The 47 nations of the Council of Europe passed a resolution calling on the nations to start "restricting or prohibiting the use of amalgams as dental fillings, explaining that "amalgams are the prime source of exposure to mercury for developed countries, also affecting embryos, fetuses (through the placenta) and children through breast feeding.

Then again, the principles of holistic dentistry, based on the research of Weston Price and Francis Pottenger, are as follows:
Avoid mercury (amalgam) fillings. If you have amalgam fillings, have them removed by a holistic dentist who specializes in mercury filling replacement. Extract teeth only when necessary, and then in such a way as to avoid leaving the jaw bone with cavitations, which can be focal points of infection.  (Editorial note:  If you have your amalgam fillings removed, ask your dentist for a metal detox chelator like DMSA or buy it yourself online.)

They also added:
Avoid root canals. If you have root canals that you suspect are causing disease, have them removed by a knowledgable dentist. (You can read more about the dangers of root canals here): http://www.foodmatters.tv/_webapp_248876/Root_Canal_Cover_Up_Exposed

So, who can we trust?  Only one person I can think of.   
                  
                     Cursed is he that...shall hearken unto the precepts of men, save their
                  precepts shall be given by the power of the Holy Ghost.    (2 Nephi 28:31)
