Veneers are a very thin layer of porcelain that is bonded to the front of the tooth. Primarily used for cosmetic purposes, veneers can be used to improve the appearance of the front teeth. If you want to change the colour, size or shape of your teeth, then veneers might be the right choice for you. As a means of restoration, veneers work best if the tooth has a good amount of enamel and at most, has only a small crack or chip, or the teeth are slightly crooked. If you have tried other means of whitening your teeth without success, then veneers can be used to enhance the colour of your teeth.
