Crowns strengthen and improve the appearance of your teeth by capping the tooth or dental implant. Crowns are made from porcelain, porcelain fused to metal, or gold. A porcelain finished crown will give the most natural appearance, blending in with the rest of your teeth. Crowns are often done to replace older, larger fillings or following a root canal operation.
A crown may take 2-3 visits; on the first visit, the tooth is prepared as the dentist recontours the tooth. A mold is then taken of that tooth and the surrounding teeth, which is sent to the dental lab. A temporary crown will be made for you; once the lab sends the finished crown, the crown will be fitted and adjusted, and then cemented.
Crowns will usually last 10 years, but many last much longer.
