What is a Tooth Crown?
According to Dr. Dale Goldschlag, of the Contemporary Dental Implant Centre, in New York City, a dental crown is a type of tooth covering which is used to cosmetically repair broken, unsightly, or partially missing teeth, or to restore stability to weakened teeth. There are several different kinds of materials that may be used in creating a crown.
• Metals, such as gold alloy, nickel, or chromium, are often the longest lasting of crown choices due to their tendency not to break, and their ability to withstand the pressure of biting or chewing.
• Porcelain-fused-to-metal crowns are cosmetically a good choice, because the porcelain can be matched to a patient’s own tooth color. However, porcelain can chip or break, and at times the metal at the base of the crown can show.
• All-resin crowns are even more prone to breakage, although they are less expensive than porcelain.
• All-porcelain or all-ceramic crowns look very natural, but are not as strong as their porcelain-fused-to-metal counterparts, and are best used for front teeth.
