Crowns

Crowns are dental restorations that cover teeth that are severely decayed or damaged. In cases where a tooth is heavily cracked or damaged, a filling may not be able to adequately restore it. As a result, a crown may be needed which covers the entire surface area of the tooth. A crown is used for a variety of reasons including:

  • Restoring a broken tooth
  • Restoring a heavily decayed or damaged tooth
  • Repairing a cracked tooth
  • Keeping a bridge in place
  • Covering an implant
  • Enhancing a tooth’s appearance


Crowns can be made from a number of materials including metal, porcelain, ceramic, or porcelain/metal. Metal crowns are stronger than porcelain crowns and make better choices for back teeth which sustain heavy chewing loads. However, porcelain crowns are more attractive since they can be customized to your teeth’s natural color. As a result, each type of crowns has its pros and cons and your dentist will help you to choose the best crown for your case.

The lifespan of a crown is at least 7 years but with good oral hygiene and care, it can last for much longer.

Depending on how much decay there is and if the dental pulp has an infection, a root canal may be required prior to placing a crown. Prior to placing the crown, your tooth will be prepared to make room for it. This could involve shaving some of the tooth's surface or creating a foundation if there is little of the tooth's structure left.

For the majority of cases, it will take two appointments to attach the crown. Once your tooth is prepared, your tooth will be placed with a temporary crown while a dental lab creates your permanent one. However, some dentists have a CEREC machine which allows them to create the crown in a single appointment. Once your permanent crown is ready, you will return for a second visit to have the temporary one removed and the permanent crown cemented to the tooth.
