Bonding is a single-visit procedure, where tooth colored resins are applied to the tooth. If you have narrow, small gaps between your front teeth, or if you have chipped or discolored teeth, you may be a candidate for bonding. Bonding is also used for patients who have uneven teeth, gum recession or tooth decay.
A very mild etching solution is applied to your teeth to create very small crevices in the tooth's enamel structure. This provides a slightly rough surface permitting a composite filled resin to bond to your tooth with an adhesive. Once placed, a high-intensity laser cures the resins onto your tooth’s surface. Each individual layer of resin hardens in less than a minute. When the layer has been applied, the bonded material is then sculpted and finely polished.
Bonding is a very conservative and affordable procedure. There are drawbacks however; perfect matching is sometimes difficult between certain teeth and the resins. Even after polishing porosity remains, so smokers and heavy coffee and tea drinkers will find that their bonding will yellow with time. Results cannot be expected to last longer than 5-7 years and minor repairs can be required.
