Dear Bryan,
Apologies for the delayed response (just returned from a long trip overseas). The metal fillings should ideally be repleaced with plastic fillings. Many dentists are well experienced with handling such materials. At the same time, it is important to take precautions such as kidney cleansing before and after the removal of old fillings to avoid parts of these toxic metals to end up in the kidneys. Taking Pau'D Arco and/or Aloe Vera juice is a good idea, too. There is more information on this subject in my book The Key to Health and Rejuvenation (www.1stbooks.com). One of the best ways to remove any kind of heavy metals from the body are kinotakara patches attached to the soles of the feet while you sleep. They draw out all toxic metals and other noxious substances, as validated by research. You can search for "kinotakara" on the web. To order you may need a distributor's ID. You can use mine which is 900003034.
