Crowns
A dental crown is a type of cap that completely covers a real tooth. Crowns can be fitted where a tooth is badly broken, decayed or has been damaged extensively; but also to make a tooth look better. 

In general there are three different types of crowns:
- a full metal crown
- a porcelain fused to metal (PFM crown)
- a porcelain crown (metal free)

To fit a crown, the old tooth will need to reduced in height and diameter so it is like a small peg onto which the crown will be fixed. Usually two separate appointments are required as it takes some time for the dental lab to make a new crown.
