If a tooth has been broken or weakened by a large filling or a lot of decay, your dentist may recommend fitting a crown (or cap). A crown looks just like a healthy natural tooth. It is made in a laboratory and then glued over the top of the damaged tooth, to disguise it. For teeth near the front of the mouth, crowns are made of ceramic materials. Crowns on back teeth may be made of ceramic, gold or a gold/porcelain combination. At Queens Road Dental Practice we use Ivoclar VIvadent Emax Press Ceramic Crowns and 3M ESPE Lava Zirconia Crowns.
Inlays and onlays are similar to fillings (in that they fill a hole in your tooth). However, like crowns, they are made in a laboratory and then cemented to the tooth with special glue. Inlays and onlays are strong and can be an attractive alternative to amalgam fillings. They are suitable for the grinding surfaces of the back teeth and can be made out of gold, porcelain or tooth-coloured filling material.
The process of preparing and fitting crowns, inlays and onlays requires two visits to the dentist.
