Crown & Bridge



A dental crown is a cap that covers a damaged tooth. The crown makes the tooth stronger and improves how teeth look.

Possible Complications

Problems with placing a dental crown 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, which may require a root canal
  • 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.
