A crown is a type of dental restoration used to fix teeth that have been broken, weakened by decay or have an extensive filling. The crown fits over the remaining part of a prepared tooth, making it durable and giving it the shape of a natural tooth. It can also be tooth coloured (if appropriate on NHS), giving the restoration a more natural appearance, so it fits in with the rest of your teeth.
A crown could be the right solution for you if you have some discoloured fillings and would like to improve their appearance. Crowns can be used to replace these to give you a more aesthetic smile. Also, if you have had root canal treatment, you will need a crown to protect or cap the restored tooth, allowing you to eat and bite down on it as if it was a real tooth.
Crowns are also used to anchor a bridge or denture firmly in place in the mouth.
