All ceramic crowns may be made of porcelain, resins, or dental ceramic materials. They create an extremely natural-looking appearance and are typically used on front teeth. The tooth-colored ceramic material is translucent, like the enamel of your natural teeth, and size and shade can be carefully matched to complement the rest of your smile. However, ceramic dental crowns are not as resilient as metal crowns and do not function as well on back teeth, which sustain a lot of pressure from biting and chewing.
