Both can improve your overall appearance by giving you a more attractive smile, but there are significant differences. Dental bonding is best for people with minor tooth damage, misshapen teeth, or mild-to-moderate cosmetic concerns - like a slightly discolored tooth. Porcelain veneers are meant to conceal more dramatic flaws. Dental bonding is more affordable and less invasive option for minor cosmetic changes. Placing a porcelain veneer will require the removal of some tooth enamel and the process can not easily be reversed.
