Crowns are synthetic caps, usually made of a material like porcelain, placed on the top of a tooth. Crowns are typically used to restore a tooth’s function and appearance following a restorative procedure such as a root canal. When decay in a tooth has become so advanced that large portions of the tooth must be removed, crowns are often used to restore the tooth.
