Silver fillings (also known as mercury amalgam fillings) were the standard of care decades ago due to their low cost and ease of use. Dr. Gene McCormick says there are inherent cautions associated with silver fillings, however. When placed, they seal a tooth for awhile, but, over time and with chewing forces, separate from the edges of the cavity in which they were placed. They are mechanically placed, not chemically bonded to a tooth and do not offer any protection from breakage of the tooth. Although no proven health risks for silver fillings exist, controversy has surrounded the fact that they contain mercury which is a toxic heavy metal.
