Full Coverage Dental Crowns
When a tooth has been extensively restored either by large fillings or a previous crown then full coverage of the remaining tooth structure is required to regain strength and durability. The tooth has to be reduced sufficiently such that the final crown looks natural and does not interfere with the bite position. These are the most destructive restorations to the tooth structure however if carried out correctly they can last a lifetime. Conventional crowns have a thin layer of gold under the porcelain to increase strength.
The latest material advances have produced all-ceramic crowns with almost the same strength.
A crown is an artificial restoration that fits over the remaining part of a prepared tooth, making it strong and giving it the shape of a natural tooth.
A crown is sometimes known as a 'cap' Crowns are an ideal restoration for teeth that have been broken, or have been weakened by decay or a very large filling.
A dental crown could be used for a number of other reasons, for instance:you may have discoloured fillings and would like to improve the appearance of the tooth you may have had a root filling which will need a crown to protect itit may help hold a bridge or denture firmly in place.
