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.
Crowns are used to cover a tooth if too much tooth structure is lost. They are also used to correct the shape or length of teeth.
They are made of beautiful porcelains these days. The bonding of porcelain to tooth structure makes it possible to make thin and natural looking crowns.
