What Are Crowns and Why Are They Used ?
A crown is a restoration that covers, or caps, a tooth to restore it to its normal shape and size. Its purpose is to strengthen or improve the appearance of a tooth.
A crown is placed to replace a large filling when there isn't enough tooth remaining to refill, to protect teeth from fracturing, to restore fractured teeth or to cover badly shaped or discolored teeth. It may also be used to attach a bridge.
It is especially important to remove plaque with dental floss when you have dental crowns to prevent gum disease.
