– A previously filled tooth where there now exists more filling than tooth. The existing tooth structure becomes weakened and can no longer support the filling.
– Extensive damage by decay.
– Discolorations and compromised esthetics.
– Root canal – After root canal, teeth tend to become brittle and are more apt to fracture. They, therefore, need to be protected by a crown.
– Bridges – When missing teeth are replaced with a bridge, the adjacent teeth require
crowns in order to support the replacement teeth.
Crowns strengthen and protect the remaining tooth structure and can improve the appearance of your teeth. Crowns can be made from different materials which include the full porcelain crown, the porcelain fused-to-metal crown and the all-metal crown. You and your dentist will decide which type is appropriate, depending upon the strength requirements and esthetic concerns of the tooth involved.
Fitting a crown requires at least two appointments. During your first visit, the tooth is prepared for the crown, an impression or mold is made of the tooth, and a temporary crown is placed over the prepared tooth. At the subsequent visit, the temporary crown is removed and the final crown is fitted and adjusted and cemented into place.
