While dental amalgam has proven itself to be an effective and relatively inexpensive material for filling cavities caused by tooth decay over the past 150 years, it is not the most pleasing aesthetic choice. Amalgam’s silver color stands in stark contrast to natural tooth color when placed in visible tooth surfaces. For this reason, patients are likely to prefer composite-resin tooth colored fillings, which can so closely approximate their natural tooth color as to be virtually unnoticeable. Composite resins may be somewhat less durable than amalgam fillings, and they may cost more, but patients’ concerns over cosmetics have made them an increasingly popular choice. As far as dentists are concerned, the best filling is no dental filling. Prevention is preferred.
P.S. Composite resin material, which is composed of a tooth-colored plastic and glass mixture, can be used to reshape disfigured teeth.
