A dental crown is a cap that conceals the visible portion of a natural tooth, protecting it from further decay or cracking, or to hide a misshapen or discolored tooth. Crowns are made from stainless steel, other metal alloys, porcelain, resin or ceramic, or a combination of these materials.
Crowns are used to cover and protect a damaged tooth. Besides strengthening the tooth, a crown can also improve its shape, alignment and overall appearance. A crown provides the functionality of a healthy tooth while the damaged one is given time to heal and repair itself.
