This restoration is a complete covering of a tooth. Unlike a filling that restores only part of a tooth, a crown can be used to restore a much larger portion of the tooth. It can also be used to repair a broken or discolored tooth, and can be used to cover an implant. The most popular type of crown is made with porcelain fused to metal(usually gold). Crowns will last for many years, but as with most dental restorations, they may eventually require repair or replacement.
