Dental Crowns & Tooth Bridges

Dental Crowns & Tooth Bridges


Bridges are natural looking dental appliances that can replace a section of missing teeth. Because they are custom made, bridges are barely noticeable and can restore the natural contour of teeth as well as the proper bite relationship between the upper and lower teeth.

Bridges are sometimes referred to as fixed partial dentures because they are bonded to the existing teeth or implants. There are several types of fixed dental bridges, all of which are fixed in position with dental cements and can only be removed by the dentist. There are conventional fixed bridges, cantilever bridges and resin bonded bridges.

Bridges can be made of porcelain, porcelain attached to metal or zirconium which is a white metal.


Crowns are synthetic caps, usually made of a material like porcelain, cemented on top of a tooth.

Crowns are typically used to restore a tooth’s function and appearance following a 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 used to restore an implant, prevent a cracked tooth from becoming worse, or an existing filling from becoming loose or fractured out.


A tooth must usually be reduced in size to accommodate a crown. An impression is then made from the existing tooth to create a custom designed crown. The impression is sent to a special lab, which fabricates a custom designed crown. A temporary crown is placed until the permanent crown is ready. The permanent crown is cemented in place.

Caring For Your Crown

With proper care, a good quality crown could last up to eight years or longer. It is very important to floss in the area of the crown to avoid excess plaque and to prevent decay around or under the crown.

Certain behaviors such as jaw clenching or tooth grinding can significantly shorten the life of a crown. Moreover, eating brittle foods, chewing ice or hard and sticky candy can compromise the adhesion of the crown, or even damage the crown.
