A crown is a cap that covers over and protects the whole tooth, restoring the tooth to the original shape, while sealing the tooth and protecting it from further damage.
Why does a tooth need to be crowned?
The following are typical reasons for doing a crown:
- When a tooth is badly broken down, a normal filling may not be strong enough for chewing
- The tooth had root canal treatment done previously
- To improve the appearance and/or contour of a tooth that is discoloured, misshaped or out of alignment
- The tooth is under heavy chewing force, has cracked, or needs protection from wear and tear
