Crowns
are a type of dental restoration which, when cemented
into place, fully cup over the portion of a tooth
that lies at and above the gum line. In comparison,
fillings are dental restorations that fill in or
cover over just a portion of a tooth. Since dental
crowns encase the entire visible aspect of a tooth,
a dental crown in effect becomes the tooth's new
outer surface.
Crowns
can be made out of porcelain (meaning some sort
of dental ceramic), metal (a gold or other metal
alloy), or a combination of both. Other terms that
are used to refer to dental crowns are "dental
caps" and "tooth caps."
