A dental crown (cap) is placed over a damaged natural tooth or on top of a dental implant to restore appearance and function. On a natural tooth, the decay is removed, the tooth is modified to create a platform and the crown is placed. On a dental implant, the crown is placed on top of an abutment and connected to the implant. Either way, a digital image or impression is made of the existing tooth in order to fabricate a new crown. Crowns can be made out of tooth-colored materials like porcelain or precious metal like gold.
