Crowns are fixed prosthetic devices, cemented onto existing teeth or implants.
Crowns entirely cover, or “cap”, a damaged tooth, both strengthening the tooth and enhancing its overall appearance, shape or alignment. Crowns can also be placed on top of implants, to provide a tooth-like shape and structure and give the implant the function of a regular tooth.
Crowns can be made from porcelain or ceramic, which can be matched to your natural tooth colour, or metal alloys and acrylic. Porcelain crowns are more attractive while alloys tend to be stronger, making them suitable for back teeth. Another option is a porcelain crown bonded to a metal shell, which is both strong and good-looking.
Crowns can be used for any of the following:
- Replacing a large filling when there isn’t enough tooth remaining
- Restoring fractured teeth, or protecting weak teeth from fracturing
- Attaching a bridge
- Covering an implant
