When a cavity is present, the decay must be removed in order to save the tooth. The void that is left after decay is removed is filled in with a material referred to as composite resin.
Back in the day, the most popular material used for fillings was amalgam, often referred to as “metal” or “silver mercury fillings”. Amalgam has been replaced by a material known as composite, allowing you to have a tooth colored filling that is actually bonded to the tooth which lowers the potential for recurrent decay around the edges of the filling. Many people elect to have their amalgam fillings replaced with tooth colored fillings (composite) for aesthetic reasons.
Tooth colored fillings can last for many years and come in a variety of shades. Dr. Roth is able to very closely match the shade of your fillings to your natural tooth color so that it will be almost impossible for people to notice.
