If you have silver (amalgam) or gold fillings, you may have considered having them replaced with tooth colored fillings (composite). Dr. Johnson does not recommend replacing this type of filling material if it is just for aesthetic reasons. Often insurance won’t cover the procedure to change to a composite filling if it is for a cosmetic reason.
Some patients have concerns about mercury being present in amalgam material. Many studies have been done showing that the filling material is safe for patients to have in their mouths. There are several metals that make up the amalgam material and when they combine, the mercury is biologically inert.
It is important to remember that anytime Dr. Johnson has to drill on a tooth, it is a type of surgery. If he were to replace a gold or silver filling with a tooth colored filling, he has to remove the tooth structure around where the old filling was to place a new filling. Anytime a tooth is worked on it can cause damage to the tooth, requiring more dental treatment.
Dr. Johnson and our team monitor all teeth for signs of decay, wear and cracks. When the time comes for a filling to be replaced for any of these necessary reasons, we would recommend replacing a silver or gold filling with a tooth colored (composite) filling.
