Advantages

Bonding is one of the easiest and least expensive cosmetic ("appearance-changing") dental procedures. Veneers and crowns are other types of tooth coverings. However, these tooth coverings must be made in a dental lab. You would need to return to your dentist’s office to have these coverings put on your teeth. Bonding usually can be done in one office visit unless several teeth need to be fixed. Another advantage, compared with veneers and crowns, is that the least amount of tooth enamel is removed. (Enamel is the hard surface layer of your teeth.) Also, unless dental bonding is being used to fill a cavity, anaesthesia is usually not required.

Disadvantages

Although the material used in composite 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 or are as strong as other methods to restore teeth, such as crowns, veneers, or fillings. Also, bonding materials can chip and break off the tooth. 

Some dentists view bonding as the best method for making small cosmetic changes, for making a temporary correction of cosmetic defects, and to correct teeth in areas of very low bite pressure (for example, front teeth).
