A crown is an artificial cover that is placed over specially prepared tooth to improve strength, function and appearance. Crowns are used most frequently when a normal type of filling is no longer suitable. The more common reasons that cause this to become necessary are:
- when the tooth has been damaged by decay;
- when tooth has been badly damaged in an accident;
- after a root canal treatment when the remaining tooth would be vulnerable to chipping or cracking;
- when a piece of tooth/filling has broken off a heavily filled front or back tooth,
- some badly discolored teeth,
- a cracked tooth.
These can be made of several materials and will be dependant on each individual’s case.
A bridge replaces one or more missing teeth. They consist of an artificial tooth anchored to teeth on each side of the gap via a crown.
