Crowns are custom fabricated, synthetic caps that are placed over the prepared natural tooth structures or dental implant abutments. They are usually made of material like gold, zirconia, porcelain, or porcelain fused to gold.
Crown is typically used to restore a tooth’s function and appearance. When the decay in a tooth has become so advanced that a large portion of the tooth must be removed, crown is often used to protect and restore the tooth structure. Crown is also used to cover an implant abutment, prevent a cracked tooth from becoming worse, or protect a root canal treated tooth from fracturing. In aesthetic and cosmetic dental procedures, crowns are used when the discolored or chipped teeth needed to be restored to their natural appearance.
A tooth must be reduced in size to accommodate a crown. After the dentist prepares the tooth, an impression is made of the prepped tooth structure. The impression is, then, sent to a dental laboratory which manufactures a custom-designed crown. A temporary crown is placed on the prepared tooth until the permanent crown is ready. Crowns are placed intra-orally with regular long lasting dental cement.
Crowns are sometimes confused with veneers, but they are quite different. Veneers are typically applied only to facial (front) surface of the teeth, where a crown is made to cover the circumference of a tooth.
Caring For Your Crowns
With proper care, a good quality crown could last a long time! It is very important to floss daily to avoid excess plaque or collection of debris around the restoration.
It is also very important to return to your dentist for your preventative care visits to have your dentistry examined.
Certain behaviors such as jaw clenching or bruxism (teeth grinding) significantly shorten the life of a crown. Moreover, eating brittle foods, ice or hard candy can compromise the adhesion of the crown, or even damage the crown.
Bridge is sometimes referred to as a fixed partial denture, because it is permanent and it is bonded to the existing teeth or implants. Bridge is a natural-looking fixed dental restoration that can replace a section of missing teeth. Because it is custom fabricated, it is barely noticeable and can restore the natural contour of your dentition. An implant bridge is similar to a traditional bridge; however, the bridge is attached to the implant fixtures below the gum line, instead of the natural tooth structures.
Zirconia, titanium, gold alloys, and porcelain are the combination of dental materials that is used to make a high quality bridge restoration in our office. Lower quality dental work using non-precious metal under the porcelain layers can result in the black line around the gum line and gingival inflammation.
