Composite bonding in combination with polishing, reshaping and bleaching, can change the color and shape of a complete smile or a single tooth. Dr. Mark Waind prefers composite bonding over veneers in many cases as it preserves more of the healthy tooth structure. Composite bonding can whiten teeth, straighten teeth, remove gaps, and correct teeth worn down by grinding. The composite bond is very durable, easily repaired, and costs significantly less than porcelain veneers.
