Fillings are the most conservative approach of restoring a tooth. When a cavity is removed, a filling is placed to restore the tooth, as long as it is not a large area of tooth structure. There are two types of fillings we use in our office.
Amalgam is made up of a mixture of silver, tin, zinc, copper, and mercury, with mercury being nearly 50% of the mixture. Amalgam material has been around and used for decades, although not esthetically pleasing, it is very durable for posterior teeth. There has been controversial literature and reports on the mercury in amalgam fillings.

Composite is made up of a plastic resin material and it has grown quite popular due to the esthetic properties of matching the shade to your teeth. We recommend placing composite restorations because they are more esthetic. Placing composites on posterior teeth typically has higher insurance copay. If you are in need of a filling, we will discuss fees with you prior to your filling appointment so you are aware.
