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.
Why would I need a Crown
A Dental Crown is often the best solution to replace large, worn fillings, repair a tooth that has cracked, has a very large cavity or has undergone Root Canal treatment. The crown covers and provides increased protection for the natural tooth beneath it. Crowns are also used to improve the appearance of natural teeth that are malformed, malpositioned or discoloured.
