Amalgam (silver fillings) – After over a 150 years of use as a filling material dental amalgam is still the most cost effective, strong, and durable filling material available.  Over 100 years of ongoing studies continue to confirm the safety of the material.  No study has found a link to any health problems or disease process.  Dental amalgam fillings are a mixture of Silver, Mercury, Copper, and Tin.  The Mercury makes up approximately 50% of the mixture and is used to bind these metals together to make a hard durable structure.  After the elements are mixed together the Mercury and other metals form a solid matrix.  This changes the chemical nature of the Mercury making it effectively harmless.
