A dental porcelain crown is a tooth-shaped 'cap' that is placed over a tooth to cover the tooth to restore its shape and size, strength, and improve its appearance. The crowns, when cemented in place, fully encase the entire visible portion of a tooth that lies at and above the gum line. They can be used as dental bridges, support large fillings and to provide protection to weak teeth from fracturing.
To prepare a tooth for a crown, your dentist will remove about 1/2 millimetre of enamel from the tooth surface, whilst maintaining the remaining natural tooth. The most important step you can take to ensure the longevity of your crown is to practice good oral hygiene. Porcelain crowns are very durable and will feel and look like your own tooth.
What are Porcelain Crowns?
Porcelain crowns are fixed prosthetic devices that are cemented onto existing teeth. Crowns are used most commonly to entirely cover a damaged tooth or cover an implant. The porcelain used is the same as used for veneers, which is strong and durable and produces a very pleasing aesthetic look.
Porcelain crowns are used to cover and support a tooth with a large filling when there is not a lot of tooth left, to hold a dental bridge in place, cover severely discoloured teeth, protect weak teeth from fracturing. In some cases an underlying metal shell, used for additional strength, is used under the porcelain.
