Chipped or cracked teeth? Bonding can fix that. Gaps or spaces between teeth? Bonding can fix that too. Bonding is a commonly used solution for fixing or repairing chipped and cracked teeth, reducing unsightly gaps or spaces between teeth, and it can even be used to hide discoloration or faded areas on the surface of a tooth. Bonding is a great way to improve the overall appearance of your teeth and enhance your already beautiful smile. Like the name says, we use a composite material, either a plastic or resin, and bond it to an existing tooth. Unlike veneers or crowns, composite bonding removes little, if any, of the original tooth.
