A dental crown is tooth-shaped cap that is permanently cemented over a tooth, in order to restore the tooth strength, shape and size, and improve its appearance. The crown will cover the visible portion of the tooth above and right at the gum line, once it is cemented into place.
Crowns are used to hold weak, broken or cracked teeth together to avoid further fracturing. Crowns are also used to support large fillings, attach a bridge, or cover discolored or deformed teeth. Crowns may also be placed over dental implants.
