Bonding, also known bonded fillings, composite fillings, or tooth-colored fillings, is a common restorative options for teeth with minor to moderate cavities or chips. The can also help improve teeth that are craacked, discolored or misaligned.
How does it work?
The tooth is prepared for the procedure by lightly etching the surface and applying a bonding liquid. Once the liquid sets, a plastic resin is applied and sculpted into the desired shape by the dentist. Once set, the resin is trimmed, smoothed and polished to a natural appearance.
The bonding procedure can often be completed in a single office visit, and can improve the appearance of a tooth significantly. However, since the plastic resin used is not as strong as your natural tooth enamel, it is more likely to stain, chip or break than natural teeth. The expected life of bonded fillings is three to five years, but they can often last longer depending on size, location, and individual circumstances.
