Mercury amalgam fillings contain 50% mercury, and continually release mercury vapor into your body. Mercury is the most toxic nonradioactive substance known to man. If you are among the growing number of people who are concerned about the mercury in your fillings, then you already known the importance of getting these removed. General dentists routinely drill out mercury filling without using safety protocols, not realizing the dangers of releasing mercury vapor to the patient, staff and dentist. A holistic dentist is trained in safe mercury amalgam removal and uses specific protective protocols and equipment to protect everyone involved.
