A crown (or cap) is a covering that encases the entire tooth surface restoring it to its original shape and size.
There are different factors that may contribute to erosion, cracking and breaking of your teeth, such as age, fillings or tooth decay. In cosmetic dentistry, crowns are used to solve these kinds of problems. Dental crowns cover the entire surface of the affected tooth adding strength, durability and stability.
Basically, there are three types of crowns: those made out of metal ideal for the back teeth; porcelain, recommended for front teeth; and porcelain fused with metal that are strong and have a natural appearance.
