Why a crown?
A crown can be done for any number of reasons:
- broken tooth
- root canal treated tooth (to protect it from breaking)
- large old filling (that can no longer support the tooth)
- reshape tooth (for appearance and/or improved bite)
A filling really only repairs a small hole. To rebuild, reshape, or protect a substantial part of your tooth, a filling just won’t do the job, and a crown is preferred. A crown is also called a cap.
Sometimes, a filling is not sufficient for long-term strength, yet there is quite a bit of healthy tooth. In this instance a partial crown or inlay is appropriate.
