Dental Crown (Cap)
A dental crown / cap is a tooth-shaped cover placed permanently over a tooth to restore its shape and size, strength, and/or to improve its appearance. Many people call it a cap. The most common crown material used is porcelain which can be matched to the appearance of the natural teeth.
Crowns may be indicated in the following situations.
To protect a weak tooth (for instance, from decay) from breaking or to hold together parts of a cracked tooth.
To restore an already broken tooth or a tooth that has been severely worn down.
To cover and support a tooth with a large filling when there isn't a lot of tooth left
To cover poorly shaped or severely discolored teeth
To cover a dental implant
To protect a Root Canal Treated Tooth Preparing a tooth for a crown usually requires two visits to the dentist -- the first step involves examining and preparing the tooth, the second visit involves placement of the permanent crown.
