Amalgam, or silver, is durable, inexpensive, and can last for at least seven years if cared for properly. However, amalgam doesn’t match the color of your teeth, and it can corrode over time, creating discoloration where the filling meets the tooth. Some people are concerned about the mercury in amalgam, but research has shown that the amount of mercury in amalgam is similar to the mercury exposure you get from other sources in the environment.
Modern technology has allowed for tooth-colored (composite) fillings, which are designed to blend in with your tooth. Because these fillings are bonded to the inside walls of the tooth, there is no chance of micro-leakage or discoloration of the tooth. These fillings last for at least five years. We recommend composite fillings for most of our patients.
