Porcelain Veneers (Laminates) may be used cosmetically to resurface teeth such as to make them appear straighter and possess a more aesthetically pleasing alignment. This may be a quick way to improve the appearance of malposed teeth without need to use orthodontics. However, the amount of malposition of teeth may be such that veneers alone may not be enough to correct the aesthetic imbalance.
Instead, orthodontics would need to be used, or orthodontics combined with veneers. The dentist who places porcelain veneersmust is extremely careful since veneers could increase the thickness of the front face of the teeth. If the teeth are too thick on the face they may appear to stand out and push out the lips. The effect may be enough to give the patient a full or chipmunk appearance when the lips are closed. Porcelain Veneers must also be created such that the patient bites into them with minimal force. Otherwise, they may chip off. So, patients whose lower jaw protrudes out farther than their upper jaw, otherwise known as a class III bite, may not be good candidates for porcelain veneers because the teeth of the lower jaw may bite into the teeth of the upper jaw such as to dislodge the porcelain veneers.
