A dental crown is a custom-fitted cap that covers a damaged, weakened, or cosmetically imperfect tooth, restoring its shape, strength, and appearance. At Tilden Dental Group in Streeterville, Chicago, IL, Dr. Jessica Reddy uses high-quality porcelain and zirconia crowns that closely mimic the look and feel of natural teeth. Crowns are one of the most versatile restorations in dentistry, used following root canals, to protect cracked teeth, to restore broken or severely decayed teeth, and to improve the appearance of misshapen or discolored teeth.
