For which purpose is coronal polishing mainly performed during dental cleanings?

Coronal polishing is primarily performed to enhance the aesthetic appearance of teeth. During this procedure, a rubber cup or a brush with a polishing paste is used to remove surface stains and plaque that may accumulate on the enamel of the teeth. This not only improves the visual appearance of the teeth by making them look cleaner and shinier but also contributes to a smoother tooth surface, which can help in preventing the accumulation of further plaque and stains.

While other aspects of dental care, such as preparation for restorative procedures, prevention of tooth decay, and reduction of periodontal disease, are certainly important in overall oral health, these are not the main focus of coronal polishing. The primary goal of the procedure lies in cosmetic enhancement, making option B the most aligned with the purpose of coronal polishing.
