Our Vermont practice uses crowns when more conservative options to restore functionality or appearance to a tooth have been discussed with you and are deemed unsatisfactory. Your All Smiles dentist most often uses dental crowns to protect a cracked tooth or restore a tooth with excessive decay or damage.
Crowns can also change the shape, shade, or even the size of patients’ teeth. If you desire an improved smile and your situation will not permit composite bonding or a porcelain veneer treatment solution, crowns can be the preferred restoration. Metal free ceramic crowns are often the treatment of choice for their cosmetic and “esthetic” benefits and life-like appearance and quality. Further, an all-ceramic crown can be created with a decreased thickness of material, which allows more of the existing tooth to remain. Modern CAD/CAM technology allows the lab, with computer generated 3-D imagery, to precisely mill your crown from a square block of ceramic material.
A crown is also a common restoration technique for a tooth that abuts a partial denture if the tooth in question does not have the proper proportions and features to clasp a removable partial denture to it. This is called a survey crown.
In preparation for receiving a crown, your dentist must remove much of the enamel on your existing tooth, as well as taper and smooth the tooth, so a crown can be placed and bonded to the remaining tooth structure. After preparing your tooth, your dentist will place a temporary crown over the tooth to protect the remaining tooth structure while your crown is fabricated in a dental lab using a molded impression taken by your All Smiles dentist. Your new permanent crown will be placed and permanently bonded during a subsequent visit. How much of your existing tooth structure remains varies with the material being used and will be determined by your dentist.
