Full ceramic crowns, also called all-ceramic crowns, are tooth-shaped caps made entirely from dental ceramic, a tooth-colored material. Unlike traditional crowns that may have a metal base, full ceramic crowns are metal-free. This makes them a good choice for people with allergies to metal or those who want a very natural look. Full ceramic crowns are strong and durable, and can be used to restore chipped, cracked, broken, or severely discolored teeth. They can also be used to anchor dental bridges or cover dental implants. Since they are tooth-colored, they blend in well with surrounding teeth.
