Tooth bonding is the application of a tooth-colored resin material using adhesives and a high-intensity curing light. The procedure gets its name because materials are bonded to the tooth. Bonding is typically used for cosmetic purposes to improve the appearance of a discolored or chipped tooth. It is also used to close spaces between teeth, to make teeth look longer, or to change the shape or color of teeth. Often times bonding is used as a cosmetic alternative to amalgam fillings, or to protect a portion of the tooth's root that has been exposed when gums recede.
Pros- Dental bonding is one of the most common and least expensive cosmetic dentistry procedures. It can usually be done in one short office visit unless multiple teeth are involved. Another advantage to bonding is that compared to veneers and crowns, it requires little to no removal of tooth enamel. Most procedures involving dental bonding do not require anesthesia.
Cons- The material used in dental bonding is not as strong as your real teeth, so biting on fingernails or chewing on pens can actually chip the material. Bonding only lasts a few years before it needs to be repaired and is not as strong as other restorative procedures, such as crowns, veneers, or fillings. It is also not as stain resistant as crowns.
Because there are some limitations to the restorative impacts that bonding can have, some dentists may 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).
