A crown is a cap used to help restore or hold together a tooth that has broken or is extensively damaged.
Crowns can also cover a large filling to help keep it in place or protect a tooth after root canal treatment.
Crowns help restore a tooth to its normal shape and size, while both strengthening and improving its appearance.
A crown is recommended for a number of reasons:
- To restore fractured teeth
- To protect weak teeth from fracturing
- To repair a tooth when there is not enough original tooth remaining
- To conceal badly shaped or discoloured teeth
- To protect teeth from fracturing following root canal treatment
- To disguise extensive damage caused by decay
- To attach a bridge
- To cover a dental implant
A crown can be made of porcelain, ceramic, gold alloys or non-precious alloys. Tooth location, the position of the gum tissue, the amount of tooth that shows in the smile, the colour and shade of the tooth and the function of the tooth are all taken into consideration when choosing which material to use.
Crowns are permanent fixtures, however they can occasionally come loose and need to be replaced. Caring for a crown requires proper dental and gum care as instructed by a dentist.
