A crown is often recommended after a root canal because the tooth may be weakened by decay, a large filling or loss of tooth structure. The crown covers the tooth and helps it handle chewing pressure.
Why the tooth becomes weaker
The root canal itself removes only a small amount from inside the tooth. However, many teeth needing treatment already have a deep cavity, crack or large old filling. This leaves less strong tooth material.
Which teeth usually need crowns?
Back teeth usually take greater chewing force and are more likely to need a crown. A front tooth with enough healthy structure may sometimes be restored differently.
What can happen without protection?
- A part of the tooth may chip.
- The tooth may split under pressure.
- The temporary or large filling may leak.
- New decay may form around the restoration.
When is the crown placed?
The dentist normally waits until the root canal is complete and the tooth is comfortable. Do not keep a temporary filling longer than advised.
Is every case the same?
No. The amount of remaining tooth, your bite and the position of the tooth all matter. Your dentist will explain the suitable restoration.
