Crowns

Crowns are a type of dental restoration which, when cemented into place, fully cover the portion of a tooth that lies at and above the gum line. In comparison, fillings are dental restoration that fill or cover just portion of a tooth. Since dental crowns cover the entire visible aspect of a tooth, a dental crown becomes the tooth’s new outer surface. A tooth may require a crown if it has been treated with a root canal to prevent fracture. Large old and cracked fillings or severely decay tooth may also require crown coverage for better long term prognosis and chewing function.
