Composite Bonding

Composite bonding is a procedure in which a tooth-coloured resin material is applied to restore or improve a person’s smile.

Composite bonding is an option:

What’s the Procedure?

Preparation. Little advance preparation is needed for composite bonding. Anaesthesia is often not necessary unless the bonding is being used to fill a decayed tooth. Your dentist will use a shade guide to select a composite resin colour that will closely match the colour of your tooth.

The bonding process. The surface of the tooth will be roughened and a conditioning liquid applied. These procedures help the bonding material to adhere to the tooth. The tooth-coloured, putty-like resin is then applied, moulded, and smoothed to the desired shape. A curing light is then used to harden the material. After the material is hardened, your dentist will further trim and shape it, and polish it to match the sheen of the rest of the tooth surface.

Time-to-completion. Dental bonding takes about 60 to 90 minutes per tooth to complete.

What Are the Advantages and Disadvantages of Composite Bonding?

Advantages: Dental bonding is among the easiest and least expensive of cosmetic dental procedures. Unlike veneers and crowns, which are customized tooth coverings that must be manufactured in a lab, bonding usually can be done in one office visit unless several teeth are involved. Another advantage, compared with veneers and crowns, is that the least amount of tooth enamel is removed. Also, unless dental bonding is being performed to fill a cavity, anaesthesia is usually not required.

Disadvantages: Although the material used in dental bonding is somewhat stain resistant, it does not resist stains as well as porcelain. Another disadvantage is that the bonding materials do not last as long nor are as strong as other restorative options, such as crowns, bridges or veneers. Additionally, bonding materials can more easily chip and break off the tooth.

Because of some of the limitations of dental bonding, some dentists view it as best suited for small cosmetic changes, for temporary correction of cosmetic defects, and for correction of teeth in areas of very low bite pressure (for example, front teeth). Consult with your dentist about the best cosmetic approach for your particular problem.
