A dental crown is a tooth shaped "cap" that is places over a prepared tooth to replace missing or decayed portions of the tooth. When cemented into place, a crown will cover the entire prepared portion of the tooth.
Crowns may be needed to cover a severely decayed or broken tooth, to hold together a cracked tooth, to support a tooth with a large filling when there is not a lot of natural tooth structure left, to cover a tooth that is misshapen or severely discolored, or to cover an implant.
Permanent crowns can be made from gold, porcelain fused to metal, or all ceramic. The location of the tooth, the force of bite and the size of the tooth all are factors that determine what material is best in each situation.
How Is A Dental Crown Placed?
A crown usually takes two visits to the office. In the initial visit the tooth will be prepared and an impression will be taken to send the laboratory that will make the permanent crown. A temporary crown usually made from resin or stainless steel will be cemented in place at this visit. During the second visit, the temporary crown will be removed and the permanent crown will be tried onto the tooth. Any adjustments that are needed will be done and the crown will be permanently cemented in place.
