Are there alternatives to dental amalgam?

Article Abstract:

Many dentists have been asked by their patients for alternatives to amalgam, the material used for fillings that contains mercury, but none exist that are as inexpensive as amalgam. Some alternatives are listed and briefly evaluated. Composite resin, the most commonly suggested material, is more costly and takes more time to prepare. In addition, it is a more difficult substance than amalgam to work with; thus it seems unlikely that dental practitioners can achieve the same quality with composite resin that they do with amalgam. Biological toxicity data have not been analyzed for this substance. Cast gold restorations are excellent but extremely expensive and difficult to place. Other options, including ceramic or resin inlays and onlays and porcelain-fused-to-metal crowns, are also more expensive and more difficult than amalgam. For most people, who have limited financial resources and dentists of average skill level, amalgam remains the only feasible choice. Moreover, those who oppose amalgam for possible health reasons should remember that other substances have not received extensive scrutiny in this regard.

Resin restorations for anterior teeth - 1995

Article Abstract:

State-of-the-art resin restorations for front teeth are long-lasting and pleasing to the eye. Large fillings in the front teeth may be visible in patients with big smiles. To promote esthetics, dentists can fill cavities in the front teeth by applying hybrid resin to the inner surface and microfill resin to the outer surface. The microfill provides a smooth, translucent, unstained surface that is often undetectable. Small cavities in the front teeth and those that are not visible during conversation or smiling can be filled with hybrid resins placed on the inner tooth surface. This material is strong and easily finished and the filling may last a lifetime. Sealing resins can be placed over resin restorations with chipped or mutilated edges, but are not necessary for routine use. Chipped resin fillings that are self-retentive may be repaired. Otherwise, the dentist must replace the filling.

Amalgam vs. composite resin: 1998

Article Abstract:

Dental amalgam remains the primary material used to restore teeth after dental caries removal. Tooth-colored composite resin materials, available since 1968, provide reliable and cosmetically superior tooth filling. Gold alloys may be the most reliable materials, but they are underutilized. Modern composites do not wear as well as amalgam, but many dentists are abandoning amalgam in favor of the newer materials. Composite resins deserve full acceptance by dentists, and insurers should adequately compensate dentists who perform restorations with these materials.
