Bonding is a term to describe the process whereby dental fillings and materials (composite) are attached to the enamel and dentine of teeth. Bonding is loosely used in many procedures today, but most people associate bonding with the process of placing white filling material on the front of the teeth to make cosmetic changes. In essence what we are doing is applying a thin layer or veneer of filling material to the front of the teeth to change the size, shape and/or colour of the teeth. It can be used to close spaces between the front teeth, repair chips or ragged/uneven edges, and even make a crooked tooth look straight.

This can be done in one appointment and often without any anesthetic. The end result can be extremely dramatic although using filling material for this purpose does have its disadvantages. The material is not as strong as enamel and because it is designed to fit into a hole or cavity, it is more likely to chip or break. Recent advances have increased the strength, durability and longevity. Over time, however the material will stain. Surface stain can easily be polished out, but some stains will penetrate the material itself and these can only be removed by replacing the material. Smoking is a big contributor to staining in the long term. Usually the bonding needs to be replaced after approximately seven to ten years.
