is a tooth
-shaped "cap" that is placed over a tooth
-- to cover the tooth
to restore its shape and size, strength, and improve its appearance. The crowns
, when cemented into place, fully encase the entire visible portion of a tooth
that lies at and above the gum line.
Crowns are an ideal way to repair teeth that have been broken, or have been weakened by decay or a very large filling. A crown could be used for a number of other reasons, for example:
- you may have a discoloured filling and would like to improve the appearance of the tooth
- you may have had a root filling and need a crown to protect what is left of the tooth
- it may help to hold a bridge or denture firmly in place.
