What is the Difference Between Silver Mercury and Plastic (tooth coloured) Fillings?
There has been a debate between the dental profession, health agencies and the public over the appropriate use of silver-mercury and plastic, tooth-colored fillings. The reality is that both materials have strengths and weaknesses and the choice between the two is one that should be made on a case-by-case, or tooth-by-tooth, basis. If economy and longevity of the filling are of primary concern and the tooth is in the back of the mouth, the silver filling may be the best choice. If appearance or the need to strengthen the remaining tooth structure is most important, the plastic materials may be appropriate.
