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.

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.

Before development of dental implants, dentures were the only alternative to replacing a missing tooth or teeth.

Implants are synthetic structures that are placed in the area of the tooth normally occupied by the root. Implants are anchored to the jawbone or metal framework on the bone and act as a foundation for an artificial tooth or permanent bridge. In some cases, implants can be used to attach dentures.

Not everyone is a candidate for a dental implant, however. For a successful implant to take hold, a candidate must have proper bone density and have a strong immune system. In all cases, dental implants require strict oral hygiene.

Implants are so well designed that they mimic the look and feel of natural teeth. Implants are usually made of a synthetic yet biocompatible material like metal or ceramic.

Surgery is necessary to prepare the area for an implant and place the implant in the mouth. Following the procedure, a period of time is required for the implant to take hold and for bone tissue to build up and anchor the device. In some cases, metal posts are inserted into the implant during a follow-up procedure to connect the tooth.

Because implants require surgery, patients are administered anesthesia and, if necessary, antibiotics to stave off infection following the procedure.

Like any restoration, implants require diligent oral hygiene and proper care to ensure they last a long time.
