Porcelain Crowns
These are similar to veneers, but are selected for teeth that are weaker, more brittle, worn, or more irregular.  Unlike veneers, they are bonded all the way around the tooth to add strength and durability.  Large-scale defects in the tooth can be caused by grinding, tooth decay, chipping, or cracking of the tooth. Any of these defects could make it necessary to place a crown to protect and preserve the remaining tooth structure.

Although gold or porcelain-fused-to-gold crowns are still used, all porcelain crowns from pure ceramic or reinforced ceramic have become more popular, especially for front teeth that are obvious when smiling or talking, and are virtually indistinguishable from natural teeth.
