Bonding is the adhesion of any restorative material to natural tooth structure or existing filling material. Composites are the most common restorative material of choice when restoring decayed or fractured teeth, for making cosmetic improvements and even changing the color of your teeth.
Bonding can also mask stained teeth, close up minor gaps and can be used to correct crooked teeth. The material is colour-matched to your tooth, sculpted and shaped to provide the desired effect, and then the surface is polished to a smooth finish. Plastic composite (and mercury) fillings are the least-expensive materials used in dentistry today. They are also, however, not the best material available for use in the mouth.
