The filling of dental cavities with unsightly metal alloys has been used throughout the history of dentistry. Contemporary fillings, however, are usually “tooth” colored and practically invisible to the untrained eye. These tooth-colored fillings can be used to replace old and worn silver amalgam, gold or other metal fillings for aesthetic purposes.
These new substances have a white color and can be made from several different substances, including composite resin, glass ionomer cement (GIC), and porcelain ceramics. These materials are very resilient and long lasting in addition to their visual advantages, but can become discolored over time. Just like metal fillings, these can be set and cured within one visit to the dentist, although they may take a little bit longer.
