The crown of the tooth is reduced in size all over and the dentist takes an impression. The laboratory makes the crown to restore the tooth to the correct shape and size. The dentist then cements or bonds the crown on to the tooth.
Crowns can be made of gold, porcelain or a bonded combination of both, each with their own distinctive advantages and disadvantages.
There are also post crowns whereby metal posts are created and bonded to the tooth's root and the crown is then fitted over the post to complete the restoration.
