Crowns completely cover the tooth on all sides, ensuring long lasting restoration of teeth. Crowns are required to repair teeth in the following situations: Teeth that have undergone root canals, teeth with large failing silver fillings, and teeth with fractures present. Crowns will prevent the unnecessary premature loss of teeth due to fractures or decay. The use of crowns is essential in any situation that requires greater strength. Crowns are fabricated from ceramic or ceramic and metal, and are indistinguishable from adjacent teeth.
Having a crown placed requires two appointments. The first appointment, the crowned tooth will be prepared and impressions are made. The impressions are used to fashion a porcelain crown that fits into the contour of the remaining teeth. While your permanent crowns are being created in a laboratory, you'll wear temporary crowns that maintain your appearance and ability to function. Approximately two weeks later, the temporary is removed and the permanent crown is cemented.
Often crowns are added to existing teeth to create better connecting surfaces for attachment of fixed bridges and partial dentures. As with all treatments, crown restorations require meticulous oral hygiene; proper brushing and flossing techniques are effective in eliminating plaque and bacteria. Crowns or caps can last the longest compared to other treatments depending on placement and forces placed on them.
