What are crowns & bridges?
Dental crowns & bridges are fixed prosthetic devices. Compared to removable devices such as denture that can be taken out for cleaning daily, Crowns & Bridges are cemented onto teeth or implants and only a dentist can remove them.
How do Crowns Work?
A crown is normally used to fully cover a damaged tooth. Apart from strengthening a damaged tooth, a crown can be used to enhance appearance, alignment or shape. A crown can also be fixed on tip of an implant to offer a tooth like shape and structure for proper function. Porcelain or ceramic crowns can be made such that it resembles the color of your natural teeth. Other materials that can be used include metal alloys, ceramic and acrylic. These alloys are much stronger compared to other porcelain and can be recommended for back teeth. Porcelain bonded to a metal shell is usually used as it is both strong and attractive.
A dentist can recommend a crown for the below situations:
- Replacement of large filling when there are not enough teeth remaining
- Guard a weak tooth from breaking
- Fix a bridge
- Cover a dental implant
- Cover poorly shaped teeth or discolored teeth
- Cover teeth that has undergone root canal treatment
