Advantages
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 laboratory, 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 veneers and 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.
Because of some of the limitations of bonding, some dentists view bonding 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 usually at the front teeth. Consult with your dentist about the best cosmetic approach for your particular problem.
