Crowns restore a tooth that has been damaged by decay, breakage or too many fillings to its normal shape and size. A crown is a tooth-shaped cap that is cemented into place over the remaining tooth – it covers the entire tooth like a helmet but looks like a natural tooth. Crowns are a common solution for worn and broken teeth, teeth that are affected by extensive decay, and teeth that need to look better cosmetically.
Once a crown is cemented into place, it functions like a new tooth. Crowns can be made from porcelain, metal, or both. The type of material used depends on many factors: how strong the crown needs to be, the aesthetic, how long it needs to last, whether it will be holding a denture and so forth.
