Our practice only places tooth colored bonded composite resin fillings, which not only look better matching the tooth enamel, but are actually chemically bonded to the existing tooth structure. This seals the junction of the enamel to the filling resisting leakage, unlike the mercury metal fillings of the past that are corroded to seal this junction. They are not chemically sealed and do have micro leakage over time.
In the past, dental cavities were filled with a mixture of metal alloys, also known as amalgam. Today, tooth-colored or composite fillings are a mixture of resin, glass or quartz and porcelain ceramics. These materials are resilient and long lasting. These fillings are colored to match the patient’s teeth and are practically invisible to the untrained eye. For aesthetic and/or medical purposes, these tooth-colored fillings can be used to replace old and worn dental amalgam, gold or other metal fillings.
