Dental Crowns Information
A crown is a restoration that fits over the top of the remaining part of a tooth. Unlike a filling which sits within the boundaries of the tooth, a crown sits out-with the boundaries of the tooth. This makes it stronger and gives it the shape of a natural tooth. To facilitate the placement of a crown your tooth will need to be prepared and shaped to a very specific shape. This shaping will allow us to make a crown that will sit beautifully within its surrounding environment.
Crowns are an ideal restoration for teeth that have become so badly broken or so heavily restored and weakened with fillings that they need additional structural support.
Crowns are usually recommended for teeth that have been root canal treated. The reason for this is that a root canal filled tooth becomes very brittle when there is no longer a nerve in it and requires additional support to prevent it from breaking. Sometimes root canal filled teeth become discoloured. The placement of a crown can disguise this discolouration, giving it the appearance of a healthy tooth again.
Crowns are usually made from either ceramic, a combination of ceramic laminated to precious metal alloy, composite or even sometimes composite bonded to precious metal alloy.
Therefore, placing a crown over your tooth will attend to your appearance, your function and your continuing good dental health.
