Silver fillings are no longer the restoration of choice for the 21st century. The lack of marginal integrity over time along with the debated issue of mercury toxicity with this material has led to the development of more modern techniques.
Popular 60 years ago, the silver filling has been replaced by partial coverage ceramic restorations that fit and function more like the natural teeth. They are maximally aesthetic and provide long term function and stability. For those patients in need of an even stronger material, gold is still utilized in partial coverage back tooth restorations where aesthetics is not a primary concern (ie in cases where bruxism has been diagnosed). Unparalleled strength and stability allows for long term function even in patients where a grinding habit is present.
