Crowns
Crowns are the restoration of choice when a filling will no longer suffice. Once a filling occupies at least 50% of the width of a tooth, a crown is recommended. Crowns surround the tooth, bracing it together, whereas a large filling acts as a wedge, weakening the tooth. Teeth with large fillings are prone to breaking or splitting.

You may need a crown for the following reasons:
- Your tooth has a large cavity
- Your tooth has had root canal therapy
- Your tooth has a large, weak filling
- To replace a failing or unacceptable existing crown
- For cosmetic improvement
Crowns can be made of several different materials — each of which may be indicated for different situations:
- Gold
- Porcelain-fused-to-metal
- All-Ceramic: This is the latest in technology, and it is becoming increasingly popular.
