Just variations: A porcelain veneer is a thin ceramic shell like a fingernail that is bonded to the front of the tooth to correct shape, size or color. Full porcelain or the newer ceramic crowns are a tooth colored covering of the complete top of tooth which can protect and change the shape or color permanently. They are also called jacket crowns. Metal crowns can be covered or veneered with porcelain on front.
