Veneers are thin shells that are attached to the front of your teeth. They are used to restore stained, discoloured, deformed, slightly damaged or maligned teeth. Veneers are mainly used to restore anterior (front) teeth by correcting their contour, colour and size to improve your smile. They are made of porcelain or composite resin. Porcelain veneers are stronger than composite resin veneers and do not change colour or stain. Generally, porcelain veneers take at least 2 visits to apply and composite resin veneers can be completed in 1 visit. Porcelain veneers generally last longer than composite resin veneers.
