Crowns are synthetic caps, usually made of a material like porcelain, placed on top of a tooth. Crowns are typically used to restore a tooth’s function and appearance following a restorative procedure such as a root canal.

When decay in a tooth has become so advanced that large portions of the tooth must be removed, crowns are often used to restore the tooth.

Crowns are also used to attach bridges, cover implants, prevent a cracked tooth from becoming worse, or an existing file is in jeopardy of becoming loose or dislocated.

Crowns also serve a cosmetic use , and are applied when a discolored or stained tooth needs to be restored to its natural appearance. A tooth must usually be reduced in size to accommodate a crown, A cast is made of the existing tooth and an impression is made. The impression is sent to a special lab, which manufactures a custom-designed crown. In some cases, a temporary crown is applied until the permanent crown is ready. Permanent crowns are cemented in place.

Bridges help maintain the shape of your face, as well as alleviating the stress in your bite by replacing the missing teeth. You and you dentist can discuss the different types of bridges to choose the best option for you:

traditional bridges, also called fixed bridges-the dentist creates a pontic or false, tooth with a dental crown on either side. the crowns are fitted over the remaining teeth to hold the false tooth into place.

Resin bonded bridges-the pontic tooth is fused to a metal band. The metal band, in turn, is bonded to the back of the remaining teeth with white resin cement

Cantilever bridge-dentists recommend this bridge when there are only teeth on one side of the gap. while traditional bridges have a crown on either side of the pontic, cantilever bridges consists of two side by side crowns and only one is connected to the pontic.

To design a bridge, a dentist must first shrink, the reshape the teeth to make room for the crowns. he or she then makes a mold of the teeth. This mold is then sent off to a laboratory, where the actual crowns and bridges are made.

With proper oral hygiene, bridges can last up to 20-25 years. However. improper or infrequent  brushing and flossing, irregular dental visits, and excessive sugar and starch intake can all bring untimely damage to the bridge
