These are restorations to repair a severely broken tooth by covering all
or most of the tooth after removing old fillings, fractured tooth
structure, and all decay. The restoration material is made of gold,
porcelain, composites, or even stainless steel. Dentists refer to all of
these restorations as "crowns". However, patients often refer to the
tooth-colored ones as "caps" and the gold or stainless steel ones as
"crowns".
