A crown is a tooth shaped cap that is placed over a prepared tooth. The purpose of a crown is to restore a tooth’s appearance, function, and strength. A crown is designed to completely cover the entire visible portion of the tooth in the mouth. Crowns can benefit a patient in some of the following situations:
- Protection of a weakened tooth from breakage or to keep a tooth that is cracked from further breakage
- A tooth that is severely worn or cracked can be capped with a crown
- When the replacement of a filling has reduced tooth structure too much, a crown can be placed to keep the structural integrity in tact
- Dental bridges can be held in place with a crown
- Teeth that are unattractive in shape or severely discolored
- Dental implants are capped with crowns
- Crowns can be used in cosmetic procedures even when structural integrity is not called into question
Crowns can be made from metals like gold, or from porcelain, porcelain fused to metal, or all ceramic.
What are Fixed Bridges?
Fixed bridges, by contrast, can be used when one or more teeth are missing or need to be extracted. A dental bridge will span the gap between missing teeth. The bridge is held in place by the teeth that are adjacent to the edentulous area. These teeth are called abutments and can either be natural teeth or implants. The result of a properly designed bridge is aesthetic, cleanable, and functional.
