Fillings essentially come in two forms: silver (amalgam restorations) and tooth colored (composite restorations). There are also other materials that may be used for specific circumstances. Both forms of restorations have proven histories of success when used in the proper circumstances as well as limitations. Dr. Millsaps prefers to use tooth colored restorations in the vast majority of cases but believes that the silver restorations still have their place in modern dentistry for specific situations. Fillings can be used in the majority of restorative cases, but as cavities grow more extensive, other forms of restorations may be necessary.
