What is a crown?

Both crowns and most bridges are fixed prosthetic devices. Unlike removable devices such as dentures, which you can take out and clean daily, crowns and bridges are cemented onto existing teeth or implants, and can only be removed by a dentist.

How Do Crowns Work?

"cap" a damaged tooth. Besides strengthening a damaged tooth, a crown can be used to improve its appearance, shape or alignment. A crown can also be placed on top of an implant to provide a tooth-like shape and structure for function. Porcelain or ceramic crowns can be matched to the colour of your natural teeth. Other materials include gold and metal alloys, acrylic and ceramic. These alloys are generally stronger than porcelain and may be recommended for back teeth. Porcelain bonded to a metal shell is often used because it is both strong and attractive.

Your dentist may recommend a crown to:

  • - Replace a large filling when there isn't enough tooth remaining
  • - Protect a weak tooth from fracturing
  • - Restore a fractured tooth
  • - Attach a bridge
  • - Cover a dental implant
  • - Cover a discolored or poorly shaped tooth
  • - Cover a tooth that has had root canal treatment

How Long Do Crowns Last?

While crowns can last a lifetime, they do sometimes become loose or fall out. The most important step you can take to ensure the longevity of your crown or bridge is to practice good oral hygiene. Keep your gums and teeth healthy by Brushing with fluoride toothpaste twice a day and flossing daily. Also see your dentist and hygienist regularly for checkups and professional cleanings.

To prevent damage to your new crown, avoid chewing hard foods, ice or other hard objects.
