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.
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.
