Crown & Bridge

You are eating dinner and suddenly you are holding half of one of your teeth in your hand. Weakened by a fracture or a large filling, the tooth is now in obvious need of repair. Dr. Mumma may suggest a crown, an artificial replacement of the upper part of the tooth, to restore the function and look of the damaged one. Crowns can be made from several different kinds of materials, and based on location, esthetics, and cost, the right one to repair your damaged tooth can be selected.

What are the most common benefits of this surgery?

Crowns are a restorative technique that repairs damaged teeth. They restore tooth function and appearance. The use of crowns and bridges also avoids shifting teeth that can happen after a tooth is lost. By maintaining or restoring the patient’s bite and their smile the effects of the tooth damage or loss are reversed.

How is the procedure performed?

During the first trip, the tooth or teeth that will be crowned will be reduced, that is, prepared to support the crown structure. This involves removing the 1-2 millimeters of tooth structure. Of course, if the tooth damage is the reason for the crown, that is the part that is removed. The reduction process leaves a thimble shape that will receive the crown.

An impression is made of the reduced teeth and a temporary crown or bridge is put in place to function while the final bridge or crown is being made. The laboratory uses the impression to custom make the final restoration. It is important that the crown fit exactly to avoid decay in the future and provide good function of the artificial teeth. During the second trip, the temporary crown is removed, the area cleaned, and the final crown is cemented or bonded into place.
