What is the primary purpose of coronal polishing in dentistry?

The primary purpose of coronal polishing in dentistry is to enhance the overall appearance of teeth by removing stains and plaque from the coronal surfaces. This procedure helps in achieving a smooth and shiny tooth surface, which not only improves aesthetics but also contributes to better oral hygiene. By polishing the teeth, any superficial stains from foods, beverages, or tobacco can be effectively eliminated, leading to a brighter smile.
