Crowns
What are crowns?
A crown is a restoration that covers, or "caps," a tooth to restore it to its normal shape and size, strengthening and improving the appearance of a tooth. Crowns are necessary when a tooth is generally broken down and fillings won't solve the problem. 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 support a large filling when there isn't enough of the tooth remaining, attach a bridge, protect weak teeth from fracturing, restore fractured teeth, or cover badly shaped or discolored teeth.
How is a crown placed?
To prepare the tooth for a crown, it is reduced so the crown can fit over it. An impression of teeth and gums is made and sent to the lab for the crown fabrication. A temporary crown is fitted over the tooth until the permanent crown is made. On the next visit, the dentist removes the temporary crown and cements the permanent crown onto the tooth.
Will it look natural?
Yes. The dentist's main goal is to create crowns that look like natural teeth. That is why dentists take an impression. To achieve a certain look, a number of factors are considered, such as the color, bite, shape, and length of your natural teeth. Any one of these factors alone can affect your appearance.
If you have a certain cosmetic look in mind for your crown, discuss it with your dentist at your initial visit. When the procedure is complete, your teeth will not only be stronger, but they may be more attractive.
Why crowns and not veneers?
Crowns require more tooth structure removal; hence, they cover more of the tooth than veneers. Crowns are stationary and are customarily indicated for teeth that have sustained significant loss of structure, or to replace missing teeth. Crowns may be placed on natural teeth or dental implants.
How should I take care of my crowns?
To prevent
damaging or fracturing the crowns, avoid chewing hard foods, ice or other
hard objects. You also want to avoid teeth grinding. Besides visiting your
dentist and brushing twice a day, cleaning between your teeth is vital with
crowns. Floss or inter dental cleaners (specially shaped brushes and sticks)
are important tools to remove plaque from the
crown area
where the gum meets the tooth. Plaque in that area can cause dental decay
and gum disease.
