A crown is used to protect teeth that have been damaged by decay, infection or injury, restoring their strength, appearance, and function.
They are often used to restore a tooth that is too damaged to support a filling — one that has undergone an intensive root canal treatment, for example.
Crowns are also used to anchor a dental bridge, cover a dental implant, and improve the cosmetic appearance of a misshapen or discoloured tooth.
Dental crowns can be made of porcelain, metal, or a combination of the two. Porcelain crowns are popular because they match the colour of your natural teeth.
A dental crown is custom-made to fit over the affected tooth. The process requires 2 appointments. First, your dentist will reshape your tooth under a local anaesthetic and take an impression of it, which will be used to produce your crown. They may also fit a temporary crown to protect the exposed tooth.
At the second appointment, your temporary crown will be removed. Your permanent crown will be checked to make sure it is comfortable and matches the shade of your natural teeth before being sealed in place.
To increase the longevity of your dental crown, practise good oral hygiene habits at home and attend regular dental check-ups and hygiene appointments.
