Crowns can be made from a few different types of materials. Older crowns were made from metals like gold alloy. Nowadays, most crowns are crafted from porcelain-fused-to-metal, all-resin, all-ceramic or all-porcelain crowns. These types of crowns have become popular as they look like natural teeth. Most people can’t tell the difference between a porcelain or ceramic crown and a natural, healthy tooth.
