Sometimes we get busy and neglect our dental hygiene for too long. And sometimes an accident or injury damages one or more teeth severely. When the tooth root is still intact, the damaged tooth itself can be covered and made fully functional.
A dental crown is a cap used to cover a tooth that has a healthy root but is too decayed to support a filling. There may be decay present, a crack in the surfaces or too much tooth broken off for a regular filling.
Three types of teeth crowns Crown procedures are all done much the same way, but teeth crowns can be made of three different substances.
Porcelain crowns These look the most natural and are very strong and durable, providing a good chewing surface on back teeth. However, they're not as durable as gold crowns.
Gold crowns Gold is very durable but not as aesthetically pleasing as porcelain because it's so obviously not your natural tooth. Therefore gold crowns are used only in the back of the mouth where they are less likely to be seen.
Porcelain fused-to-metal These teeth crowns have a metal lining inside the porcelain exterior and are natural looking like regular porcelain crowns, and more durable because of the metal lining. However, as the years pass and our gums start receding, the metal lining can start to show as a dark stripe along the gumline.
Dental Crowns Procedure
During your first visit, the tooth is shaped to remove all decay and damage. Then an impression or mold is taken and sent to the dental lab where the crown will be custom-made. While you wait, you can have a temporary crown covering that tooth, to protect it and to give you a better chewing surface.
In your second visit, approximately two weeks after the first, Dr. Matin attaches the crown temporarily, and has you bite down, to test the crown's shape. If necessary, she'll do some fine-tuning, until your teeth meet in the correct, smooth way.
When both you and she are satisfied, she'll use dental cement to permanently attach the crown, and it becomes your new tooth.
