An artificial replacement for the crown of a tooth that has become decayed, discoloured, or broken. A porcelain crown is usually used on front teeth, but back teeth require the greater strength of a crown made from gold or porcelain fused to metal. A crown may be fitted by filing the natural tooth to form a peg and cementing the crown over the top. If the tooth is badly decayed or weakened, it may be necessary to remove the entire natural crown of the tooth and then fit the artificial crown onto a post cemented in the root canal.
