Crowns can be utilized to improve look also. They might be positioned to cover misshapen or badly discolored teeth.
Crowns can be made ahead of time (upraised) or made to order in a laboratory. Upraised crowns are made of plastic or stainless steel. They can be used on a temporary basis till an irreversible crown is made.
Crowns can be made from:
- All metal
- Porcelain fused to metal (PFM).
