Permanent crowns can be made from all metal, porcelain-fused-to-metal, all resin, or all ceramic.
• Metals used in crowns include gold alloy, other alloys (for example, palladium) or a base-metal alloy. Compared with other crown types, less tooth structure needs to be removed with metal crowns, and tooth wear to opposing teeth is kept to a minimum. Metal crowns withstand biting and chewing forces well and probably last the longest in terms of wear down. Also, metal crowns rarely chip or break. The metallic color is the main drawback. Metal crowns are a good choice for out-of-sight molars.
• Porcelain-fused-to-metal dental crowns can be color matched to your adjacent teeth (unlike the metallic crowns). However, more wearing to the opposing teeth occurs with this crown type compared with metal or resin crowns. The crown's porcelain portion can also chip or break off. Next to all-ceramic crowns, porcelain-fused-to-metal crowns look most like normal teeth. However, sometimes the metal underlying the crown's porcelain can show through as a dark line, especially at the gum line and even more so if your gums recede. These crowns can be a good choice for front or back teeth.
• All-resin dental crowns are less expensive than other crown types.
• All-ceramic or all-porcelain dental crowns provide the best natural color match than any other crown type.
• Temporary versus permanent. Temporary crowns can be made in your dentist's office whereas permanent crowns are made in a dental laboratory. Temporary crowns are made of acrylic or stainless steel and can be used as a temporary restoration until a permanent crown is constructed by the dental laboratory.

My dentist (Dr. Candy Ugalde in Riberas del Pilar) presented me with the option of a zirconium crown, guaranteed for six years.
