What should I pay attention to when making dental veneers?

Tooth veneering is to reshape the shape and color of teeth with special dental materials after grinding off a layer of the surface of the labial side (the side facing the outside) of teeth. According to different materials and repair methods, veneers can be divided into porcelain veneers and resin veneers.

Preparation of veneer

Sticking to teeth can whiten teeth. Resin veneer is a layer of resin material which is similar to the color of normal teeth and covers the color of teeth, and the effect is good in a short time.

Veneer needs to be replaced around 2000, and it is rarely used now.

Porcelain veneer is to grind off a layer on the outer surface of the tooth facing the outside, that is, the lip side of the tooth, and then re-create the tooth shape with special dental porcelain materials according to the patient's face shape, adjacent teeth and other reference conditions, and choose the color that the patient is satisfied with. It has good cosmetic effect and certain wear resistance, but it is brittle and easy to collapse due to unreasonable stress. The retention force is completely from the adhesive force, and it is easy to fall off when the external force is too large.
