Crowns and Bridges

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 upper and lower teeth.

Bridges are sometimes referred to as fixed partial dentures, because they are semi-permanent and are bonded to existing teeth or implants. There are several types of fixed dental bridges (cannot be removed), including conventional fixed bridges, cantilever bridges and resin-bonded bridges.  Unlike a removable bridge, which you can take out and clean, your dentist can only remove a fixed bridge.  .

Porcelain, gold alloys or combinations of materials are usually used to make bridge appliances.

Appliances called implant bridges are attached to an area below the gum tissue, or the bone.

Crowns

Crowns are synthetic caps, usually made of a material like porcelain, placed on the 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 filling is in jeopardy of becoming loose or dislocated. Crowns also serve an aesthetic use, and are applied when a discolored or stained tooth needs to be restored to its natural appearance.

Procedures

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 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.

Crowns are sometimes confused with veneers, but they are quite different. Veneers are typically applied only to relatively small areas.

Caring For Your Crowns

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 or collection of debris around the restoration.

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.

Ridge Augmentation

If you lose one or more permanent teeth, an indentation may result in the gums and jawbone where the tooth used to be. When no longer holding a tooth in place, the jawbone recedes and the resulting indentation looks unnatural. Ridge augmentation is a procedure that can recapture the natural contour of the gums and jaw. A new tooth can then be created that is natural looking and complements your smile.

Bonding

Bonding is a process in which an enamel-like material is applied to a tooth`s surface, sculpted to an ideal shape, hardened, and then polished for an ideal smile. This procedure usually can be accomplished in a single visit.

Bonding is often performed in order to fill in gaps or change the color of your teeth. It typically only entails one office visit, and the results last for several years.

Bonding is more susceptible to staining or chipping than other forms of restoration such as veneers. When teeth are chipped or slightly decayed, bonded composite resins may be the material of choice. Bonding also is used as a tooth-colored filling for small cavities and broken or chipped surfaces.

In addition, bonding can be used to close spaces between teeth or cover the entire outside surface of a tooth to change its color and shape. Crowns, also known as caps, are used in cases where other procedures will not be effective. Crowns have the longest life expectancy of all cosmetic restorations, but are the most time consuming.

Grafts

Soft tissue grafts are sometimes performed to treat gum disease, or correct other abnormalities.

The procedure involves taking gum tissue from the palate or another donor source to cover an exposed root in order to even the gum line and reduce sensitivity.

Periodontal procedures are available to stop further dental problems and gum recession, and to improve the aesthetics of your gum line.  For example, an exposed tooth root resulting from gum recession may not be causing you pain or sensitivity, but is causing one or more of your teeth to look longer than the others. In other cases, an exposed tooth root causes severe pain because it is exposed to extremes in temperatures or different kinds of food and liquids.

Once contributing factors are controlled, a soft tissue graft procedure will repair the defect and help to prevent additional recession and bone loss.
