While traditional dentistry focuses on oral hygiene and preventing, diagnosing and treating oral disease, cosmetic dentistry focuses on improving the appearance of a person's teeth, mouth and smile. In other words restorative, general and/or family dental practices address dental problems that require necessary treatment, whereas cosmetic dentistry provides elective — or desired — treatments or services.

Cosmetic dentistry may also provide restorative benefits. For example, dental fillings are a common procedure used to treat decayed teeth. Previously, most dental fillings were composed primarily of gold, amalgam and other materials that left visible dark spots on the teeth.
