Dental Crowns

A crown is one of the most effective and versatile dental treatments. They are used to restore the strength, function, and beauty of a damaged tooth. For example, when a tooth has sustained a large enough cavity, much of its strength is lost due to the void that was created and the tooth becomes too fragile for daily use. A crown can offer superior strength and protection to the tooth, while also restoring the beauty and natural look of your smile. At Central Maine Dentistry, we offer porcelain or zirconia crowns to ensure strength and esthetics.

You may need a crown if you:

  • have a cavity that is too large for a filling
  • have a missing tooth and need a bridge
  • need to cover a dental implant
  • have a tooth that is cracked, worn down or otherwise weakened
  • have had root canal treatment—the crown will protect the restored tooth
  • want to cover a discolored or badly shaped tooth and improve your smile

How is a crown placed?

Several steps are involved, and two dental visits are generally needed to complete the treatment.

  • The dentist prepares the tooth by preparing the tooth circumstantially, so the crown will fit. Any decay is also removed. If additional tooth structure is needed to support the crown, the dentist may build up the core of the tooth.
  • An impression is made to provide an exact model for the crown.
  • A temporary crown will be made before you leave your first appointment, and will protect the tooth you while wait for the permanent crown to be ready—usually between two to three weeks. While you have the temporary crown, this tooth may be sensitive to hot and cold and you should avoid chewing gum or sticky foods during this time.
  • The dentist or a laboratory technician then uses the model to help make the crown.
  • When the new crown is ready, the dentist places it in your mouth and makes the necessary adjustments. When you and your dentist are satisfied with how it looks and feels, the crown is cemented in place.
