Dental Benefit, All-Ceramic or All-Porcelain Dental Crowns
These types of crowns provide better natural color match than any other crown type and may be more suitable for people with metal allergies. However, they are not as strong as porcelain-fused-to-metal crowns and they wear down opposing teeth a little more than metal or resin crowns. All-ceramic crowns may be a good choice for front teeth.
