Small teeth defects can be safely restored directly with the filling material. Occlusal surface of the teeth or incisal edge anatomy and esthetics can be restored using modern filling materials and techniques. Where teeth surfaces are exposed to significant load, the walls of the teeth are thin, and in other cases, where the shape of the teeth will be modified substantially, dental fillings are often not recommended because of less favorable long-term success.
Improvement of filling materials has expanded their indications for use. Thus, it is often possible to avoid unnecessary dental prosthetics by using dental fillings as a less invasive and more cost-efficient method. It is very important that fillings have well integrated (smooth) margin and is easily maintained. The filling should properly restore proximal contacts with adjacent teeth, and should not introduce occlusal interferences during mastication.
