Dental crowns fall into three categories: full metal, porcelain fused to metal, and porcelain. Your dentist will assess your dental health and discuss your options with you, but all three crown types have distinct advantages.
Precious metals have tremendous durability and are non-reactive. These characteristics make them a preferred material for dental crowns. Gold alloys are the most common metal for crowns. Metal crowns offer outstanding longevity, but because they look nothing like natural tooth enamel, they are most often used for molars where they will not be as visible. With the rising costs of precious metals that are the most expensive type of crown.
Porcelain fused to metal (PFM) conceals metallic surfaces under a ceramic layer that closely resembles natural tooth enamel. Because of their metal cores, these crowns reveal their underlying structure in strong light and lack the translucency of natural teeth. There are instances where the porcelain can also fracture off of the metal substructure of the crown.
Porcelain crowns have the most natural look and are generally indistinguishable from natural teeth. Due to advancements in ceramics, they are every bit as strong as metal or PFM crowns. New CAD/CAM techniques allow dentists to create crowns in minutes, but the procedure is typically costly. Porcelain crowns made in this way wear at the same rate as natural teeth.
These crowns are the newest technology out on the market and are the most widely used at our clinic. They are made out of a white metal. This allows them to have the aesthetics of a porcelain crown but have the strength of a metal crown.
