Metal fillings have been around for a significantly long time, and to this day, they do an adequate job in filling teeth. Today's white fillings are, by far, a patient's first choice because of their natural cosmetic benefits. Metal fillings still have their own benefits. Metal fillings (also known as amalgam fillings) are very strong and do not wear out as quickly as composite (white) fillings. This is great for patients who have large areas that need to be filled. Metal fillings generally cost less than natural-looking white composite fillings, so patients who need fillings in any out-of-sight teeth often consider a metal filling.
