What is the purpose of coronal polishing?

To strengthen teeth
To remove stains and plaque
To prepare for surgery
To whiten teeth

The correct answer is: To remove stains and plaque

Coronal polishing is a dental procedure used to remove surface stains and plaque from teeth, typically using a polishing paste and rubber cup. It is commonly performed during a routine cleaning to help achieve a brighter, cleaner smile. While some people may believe it strengthens teeth or whitens them, its main purpose is to remove surface build-up and improve the overall appearance of the teeth. Additionally, it is not used as a preparation for surgery, as this is typically done through more invasive procedures.
