Crowns-Dental otherwise known as "caps"
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 (gold or precious metal). You and Dr. Farley 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.
Some of the indications for a crown are:
- 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. Often times a crack may be visible, but not yet symptomatic (hurting to hot, cold or biting). Having the crown may help reduce the necessity for a root canal.
- Cracked Tooth Syndrome (CTS) - A tooth may exhibit pain with pressure, and this can be a sign of an internal fracture, usually due to a previously placed silver filling that expands and contracts with temperature changes. The only way to prevent the tooth from flexing is to place a crown to hold the cusps together.
- Root canal - After a root canal, teeth tend to become brittle and are more apt to fracture. These teeth 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.
