A crown is a cap or cover that is place over a damaged tooth to form its normal shape, size, and function.
Crowns can be used to protect a tooth or improve the way a tooth looks. Crowns may be recommended for the following reasons by your dentist:
- support a tooth that has a large filling when there isn’t enough natural tooth structure.
- protect a tooth that may be weak from fracturing
- restore a tooth that has fractured
- cover a badly shaped or discoloured tooth
- to protect a tooth that is undergone root canal treatment
- attach a bridge to replace missing teeth
- cover a dental implant
A crown can be made from several different types of materials. To decide it is best to think about the tooths’ location and function.
- The position of the gum tissue
- The amount of tooth that shows when you smile
- The colour and shade of the surrounding teeth
The process of making a crown involves shaping the tooth and taking a mould of the prepared tooth. The dental laboratory constructs the crown from the mould.
Crowns can be constructed from various different materials – metal alloys, ceramic bonded to metal, or all-ceramic crowns where a very natural aesthetic result is required.
Most often the crown is tooth coloured so that it can blend in with your natural teeth.
It is important to take care of your new crown by brushing carefully where the edge of the crown joins the tooth where bacteria can build up.
