A dental crown is a cap that covers a damaged tooth. The crown
makes the tooth stronger and also improves how the teeth look.
Reasons for Procedure A dental crown may be needed if your tooth
is broken, decayed , worn down, or severely discolored. Crowns
are also used to: - Support teeth after a filling, dental
implant , or dental bridge has been placed - Protect the tooth
after a root canal - Treat chewing problems Problems from the
procedure are rare, but all procedures have some risk. Your
dentist will review potential problems, like: - Allergic
reaction to the materials in the crown or the local anesthesia -
The need for additional procedures if the crown becomes chipped
or loose - Damage to the tooth's nerve—root canal may be needed
- Decay of the crowned tooth if bacteria gets into the tooth -
Sensitive teeth, especially when consuming something hot or cold
- Dark line on the gum where the crown is placed if a metal
crown is used Talk to your dentist about these risks before the
procedure. What to Expect
