Crowns are a complex restoration recommended when no other simpler restoration can be utilized to save, preserve, or strengthen a tooth. It is recommended when teeth are fractured, stained, damaged, or used to attach a bridge. A crown is a restoration that covers, or caps a tooth, to restore it to it’s normal shape and size. Its purpose is not only to strengthen, but to improve the appearance of a tooth.
Both aesthetics and function are considered when choosing the type of materials most suitable for you. There are many factors involved such as tooth location, position of the gum tissue, the amount of tooth that shows when you smile, the colour or shade of your tooth and the function of the tooth.
Crowns are made from a number of materials: all gold, porcelain fused to a precious metal alloy, or all ceramic. All have a specific place in restorative dentistry depending upon the functional and aesthetic demands of the patient.
All Ceramic Crowns
All ceramic crowns are metal free. These new restorative materials demonstrate properties similar to those of natural teeth. They are used in areas of low functional demand and high aesthetic requirements.

Porcelain Fused to Metal Alloy Crowns
