What is a common characteristic of cosmetic dentistry?

Cosmetic dentistry is primarily concerned with enhancing the appearance of a person's teeth, gums, and smile. This branch of dentistry includes procedures like teeth whitening, veneers, bonding, and orthodontics that aim to improve the overall aesthetics of a person's smile. The focus on aesthetics distinguishes cosmetic dentistry from other areas of dental practice that may prioritize health or function over appearance.

Restoration of health, addressing dental emergencies, and treatment of periodontal disease are all significant aspects of general dentistry and oral health care, but they do not directly pertain to the enhancing aspect that characterizes cosmetic dentistry. Thus, the enhancement of dental aesthetics is the defining feature that sets cosmetic dentistry apart.
