A crown, also known as a “cap”, is a type of dental restoration that fully covers the part of a tooth or dental implant that is exposed above the gum line. Once placed, it becomes the tooth’s new outer surface. As opposed to dental fillings that just fills in or repairs a portion of a tooth. Crowns are permanently cemented into place and are fixed. The crown (or cap), is matched to look like the rest of teeth. The dentist will adjust the shape so that it fits perfectly. The color will also be chosen to match the patient’s natural tooth color.
