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 restore a tooth when there isn’t enough of the tooth remaining to provide support for a large filling, 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, it is reduced so the crown can fit over it. An impression of the teeth and gums is made and sent to the lab for crown fabrication. A temporary crown is fitted over the tooth until the permanent crown is made. On the next visit, Dr. Argyle will remove the temporary crown and cements the permanent crown onto the tooth.

Crowns should last approximately five to eight years. However, with good oral hygiene and supervision, most crowns will last for a much longer period of time. Some damaging habits like grinding your teeth, chewing ice or fingernail biting may cause this period of time to decrease significantly.

To prevent damaging or fracturing the crown, avoid chewing hard foods, ice, or other hard objects. You also want to avoid teeth grinding. Besides visiting Dr. Argyle and brushing twice a day, cleaning between your teeth is vital with crowns. Floss or interdental 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.

Gum disease, or periodontal disease is a chronic inflammation and infection of the gums and surrounding tissue. It is the major cause of about 70 percent of adult tooth loss, affecting three out of four persons at some point in their life. Periodontal diseases include gingivitis and periodontitis.
