What is a dental crown?

A dental crown is a dental device in the form of a cap that covers a tooth to restore the size, strength and shape of the tooth. A crown covers the entire visible tooth when used.

A dental crown protects a weak tooth from breaking. The procedure is effective when restoring an already broken tooth. A dental crown is also used to hold a dental bridge in position and to cover dental implants. Children may have dental crowns to cover teeth that have decayed, as stated by WebMD.

There are different types of dental crowns, including all-resin, metal, porcelain, stainless steel and milled. There are also permanent and temporary crowns that are used, depending on the condition of an individual's teeth.
