Crowns are ideal for patients whose teeth are damaged or decayed, but aren't strong enough to support fillings.
The normal treatment for a broken or decayed tooth is removal of all the decay and then filling with a strong material. Sometimes damage or tooth decay can reach a point where not enough healthy tooth left to support a filling. In these cases a crown can be the best alternative to an extraction. Teeth can also blacken if the nerve is damaged so a crown can be used to give the appearance of a natural tooth.
A crown, sometimes called a cap, is a tooth coloured porcelain material that is moulded to mimic the shape of the decayed tooth. A combination of a pin and either dental cement or resin is used to attach the crown to the tooth. Crowns can be both fitted over teeth and in some cases attached to a root.
