A crown is a type of dental restoration which completely caps or encircles a tooth or dental implant. Crowns are often needed when a large cavity threatens the ongoing health of a tooth. They are typically bonded to the tooth using a dental dental cement. Crowns can be made from many materials. Crowns are often used to improve the strength or appearance of teeth. While arguably beneficial to dental health, the procedure and materials can be relatively expensive.
