Metal crowns or made of either noble metal alloys (some combination of gold, silver, platinum, palladium, and copper) or base metal alloys, such as nickel or chromium. Base metal are often discouraged as they typically cause allergic reactions. Metal crowns are the longest-lasting type of crown and are nearly impossible to chip or break, making them quite durable. The main drawback is their color and cost.

Porcelain-fused-to-metal crowns are metal coated in an outer layer of porcelain that can be blended to match the natural color of adjacent teeth. Porcelain is aesthetically pleasing but the wear on them can be extensive and they are more susceptible to breaks and chips. In some cases, the metal may start to show near the gums, especially if the patient suffers from gum recession.

All-porcelain or all-ceramic crowns are the most natural looking crowns available today and make for a beautiful smile. In the past they were mostly used only for front teeth; however, in recent years with improved technology they have become stronger, making them one of the most sought after crown types. They may be somewhat abrasive against other teeth when chewing, but this is the only drawback.
