Crown is a fixed dental prosthetic device that is cemented on the existing teeth or implants. A crown or “cap” covers the entire surface of a damaged tooth. It not only strengthens a damaged tooth, it improves its appearance, shape or alignment as well. It may be placed on an implant too to give a tooth-like shape and structure for function. . Materials used to make a crown include—porcelain, ceramic, gold and metal alloys, and acrylic. Crowns made of porcelain or ceramic match the color of your natural teeth. As the alloys are stronger than porcelain they are preferred for back teeth.

Porcelain bonded to a metal shell is often used because it is both strong and attractive.
