Dental bonding is a cosmetic dental procedure in which a tooth-colored, composite resin material is applied and bonded to existing teeth. Bonding is most often used for cosmetic purposes. It can be used to repair chipped or broken teeth. It can also be used to close spaces between teeth, to make short teeth appear longer, or to change the shape or color of teeth. Today, bonded restorations are used as a better alternative to silver or gold fillings. Bonding can also be used to protect and restore worn and sensitive roots that have become exposed due to gum recession.
The dental bonding procedure typically takes between 30 minutes and one hour to complete. First, your dentist will match the color of the resin to the color of the original tooth so it appears completely natural. Then, using microabrasion technology, your dentist will slightly roughen the surface of the the tooth using chemicals, lasers or other microabraders. After placing, shaping and contouring the composite resin, it is bonded to the tooth using a fiber optic light. It is then polished to give it a natural appearance.
With proper upkeep, dental bonding can last for many years. Proper upkeep includes brushing at least twice a day, flossing at least once a day, and maintaining a healthy diet.
