When a tooth is badly decayed or damaged a tooth shaped covering called crown is used to cover the tooth. Crowns are used in situations where the tooth cannot be replaced by fillings or other methods. Misshapen and discolored tooth can maybe covered by crowns. Parts of a cracked tooth or a bridge can be held together by a crown.
If large amount of decay is there, a root canal treatment maybe needed prior to placing of the crown. A foundation is built up first to support the crown. The tooth is filed down so that there is enough room for placing the crown. The impressions of the teeth are taken and sent to lab for manufacturing the crowns as per requirement. Firstly a temporary crown is placed on the tooth until the permanent one is manufactured.
