Dental bonding is a procedure in which a tooth-colored resin material (a durable plastic material) is applied and hardened with a special light, which ultimately “bonds” the material to the tooth to restore or improve person’s smile. Dental bonding is an option that can be considered:
- 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
- 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.
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 or veneers. Additionally, bonding materials can chip and break off the tooth.
Because of some of the limitations of dental bonding, it is seen 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 us about the best cosmetic approach for your particular problem.
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 us.
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.
