A crown is a full cover or porcelain that fits over your tooth. Porcelain crowns can be colour matched to your surrounding teeth. The best results with crowns are achieved when the underlying foundation is sound. To this end, we usually replace any old fillings before placing a crown. In root filled teeth that do not have enough remaining structure, we may also need to place a post in addition to a new core filling.
Dental crowns are fitted to repair a tooth and help reduce the risk of fracture.
We routinely recommend the placement of crowns on teeth that have been heavily filled, as these teeth are at high risk of chipping and cracking. Occasionally teeth are crowned to improve their appearance. Crowns are usually constructed in porcelain, to match your natural teeth. We can also make crowns in gold if required.
Before the placement of a crown we will review the condition of the tooth and assess the health of the root via a radiograph. During the first appointment, any old filling material is removed, and the tooth is shaped so a crown will fit over the top. We take a digital scan of the preparation and email this to our laboratory. A temporary crown will then be placed while your porcelain crown is being constructed. This is normally worn for 2 weeks.
During the second appointment, the temporary crown will be removed, and the porcelain crown fitted and bonded to your tooth.
