A crown is an artificial shaped cap, used to cover a damaged or decayed tooth. It looks and acts like a natural tooth and can be used as part of an implant procedure.
Crowns are a popular choice for people who have discoloured or crooked teeth. In these cases they are an aesthetic choice rather than a medical necessity. They can be made from ceramic, metal or porcelain fused to metal and last from at least 7 years to 40 years!
If you need a crown then you may have to undergo root canal treatment as well although this will depend on the extent of the decay. Another factor is the risk of injury or infection to the tooth’s pulp (centre of the tooth).
