Bonding is a process in which an enamel-like (tooth-colored resin) dental composite material is applied to a tooth's surface, sculpted into shape, hardened with a special light (which ultimately bonds the material to the tooth) and polished. This procedure is often used when a filling is too small to correct the decayed teeth and a crown would be excessive. It is best suited for small cosmetic changes, for temporary correction of cosmetic defects, and for correction of teeth in areas of very low bite pressure (e.g. front teeth).    

 

What Conditions Is Dental Bonding Considered?

• To repair decayed teeth (composite resins are used to fill cavities).

• To repair chipped or cracked teeth.

• To improve the appearance of discolored teeth.

• To close spaces between teeth.

• To make teeth look longer.

• To change the shape of teeth.

• As a cosmetic alternative to amalgam (silver) fillings.

• To protect a portion of the tooth's root that has been exposed when gums recede.

 

What Are the Advantages and Disadvantages of Dental 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, anesthesia is usually not required.

 

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

 

Do Bonded Teeth Require Special Care?

Bonded teeth do not require special care. Simply follow good oral hygiene practices. Brush teeth at least twice a day, floss at least once a day, rinse with an antiseptic mouthwash once or twice a day and have regular professional check-ups and cleanings. Because bonding material can chip, it is important to avoid such habits as biting fingernails; chewing on pens, ice, or other hard food objects; or using your bonded teeth as an opener. If you do notice any sharp edges on a bonded tooth or if your tooth feels odd when you bite down, call for an appointment. 

 

How Long Does Bonding Material Last?

The lifespan of bonding materials for the teeth depends on how much bonding was done and your oral habits. Typically, however, bonding material lasts from three years up to about 10 years before needing to be touched up or replaced.
