In size and shape, crowns look like the top portion of a natural tooth. They can be made from a variety of durable materials, including gold, porcelain or porcelain-fused-to-metal. Metal crowns are typically used for molars, or back teeth, while porcelain is more commonly used for teeth that show while smiling or talking. All crowns have a hollowed-out section inside, which allows them to fit snugly over the top of a natural tooth. The only exception are crowns that are used in the middle section of a bridge; these restorations are solid because they are taking the place of a missing natural tooth.
Dentists prepare natural teeth for crowns by first taking measurements of the space where the crown will be placed. The next part of the process involves removing any decay and preparing the tooth for the dental crown. This shape will correspond with the crown, which can be designed in a laboratory or prepared in-office while you wait. A bonding cement is applied to the prepared tooth and the crown is attached in place, with any necessary adjustments made to ensure a perfect fit.
With proper care and regular checkups, crowns can last as long as 20 years, allowing the wearer to smile and eat normally without risking the health of the remaining teeth.
