Crowns
A crown is a restoration that covers a tooth to restore it to its normal shape and size, strengthening and improving the appearance. Crowns are necessary when a tooth is broken down and fillings won't solve the problem any longer. If a tooth is cracked, a crown holds the tooth together to seal the cracks so the damage doesn't get worse. Crowns are also used to attach a bridge, protect weak teeth from fracturing, restore fractured teeth, or cover badly shaped or discolored teeth. To prepare the tooth for a crown, the tooth is reduced so the crown can fit over it something like a thimble. An impression of teeth and gums is necessary for crown fabrication. If you have a certain cosmetic look in mind for your crown, discuss it with your dentist at your initial visit. Perfect results are not always possible as there is no substitute for a healthy tooth. To prevent damaging or fracturing the crowns, avoid chewing hard foods, ice or other hard objects. You also want to avoid teeth grinding.
