Fillings. Fillings are used to repair a cavity in your tooth caused by decay. The most common type of filling is dental amalgam, made from a mixture of mercury and different metals. Dental amalgam fillings are often used on your back teeth as they are hard-wearing.
Amalgam is one of the best filling materials when dentists need to place fillings in areas of the mouth that are difficult to keep dry, such as molars (back teeth) or cavities below the gumline. Resin fillings need a specific environment in which to be placed; for example, the prepared tooth must be completely dry when the resin material is being applied and cured.
