CROWNS

WHAT IS A CROWN? A protective covering for a tooth, fabricated from either gold or porcelain fused to metal (Other names: cap, jacket)

WHY WOULD A TOOTH NEED A CROWN? Crowns are usually made to protect particularly weakened teeth from fracturing. Weak teeth are those with extensive decay, very large previous fillings,root canals or a history of fracturing. If a weakened tooth fractured badly it might need root canal treatment or even to be extracted A crown greatly decreased the risk of tooth fracture. Tooth colored crowns (porcelain fused to metal) are also sometimes done to improve the appearance of unsightly front teeth.

DOES INSURANCE COVER IT? Most insurances cover a portion of crowns (usually 50%or more) and build-ups as long as they are not done solely for cosmetic reasons. Crowning healthy front teeth with little or no decay to improve your smile would not be covered. If a tooth needs a crown, however, you may choose to have it be done in porcelain (vs. gold) for cosmetic reasons and it would still be covered.

WHAT ABOUT MY PORTION OF THE COST? We request your estimated portion at the time we start the crown. Your portion must be paid in full before the crown is cemented.

HOW LONG DOES IT TAKE? In most case two appointments are needed The first for about

60-90 minutes ,involves shaping, making a mold, choosing materials (gold or porcelain), and placing a temporary crown on the tooth. The second, usually 3-4 weeks later, for about 30 minutes, involving removing the temporary and cementing the gold or porcelain crown. It is very important to keep your second appointment If the temporary crown is left on much longer than 3-4 weeks the gold or porcelain crown may not fit and new molds would have to be taken and possibly more drilling done. There is an additional charge if the crown does not fit and must be remade because you did not keep your second appointment In addition, extended time in a temporary crown may cause permanent tooth or gum damage, and even loss of the tooth and surrounding teeth.

HOW LONG DOES A CROWN LAST? It depends largely on your personal habits. Heavy sugar eaters and those with poor cleaning habits will generally need their crowns replaced more quickly than those with a more careful diet and good cleaning habits. Detecting decay under a crown is difficult and x-rays do not always show it Patient complaint of discomfort is often the first indication that a new crown may be needed. Some studies show 7-12 years being an average range but 15 or even 2Oyears is not unusual

IS ONE TYPE BETTER THAN ANOTHER? Gold is without question the most durable, although it is generally considered objectionable near the front of the mouth. Modem porcelains are not quite as strong and may chip, however, this is not frequently seen and is mainly on molars. If a porcelain crown does chip, it is generally only a cosmetic concern-the tooth itself is still protected by an underlying layer of metal We recommend gold for those teeth you cannot easily see when talking or smiling and porcelain for any teeth you feel do show.
