What type of stains can coronal polishing typically address?

Coronal polishing primarily targets extrinsic stains, which are deposits of discoloration present on the outer surface of the teeth. These stains are caused by various factors, including food, beverages (like coffee and tea), tobacco use, and poor oral hygiene. The polishing process uses abrasive materials to effectively remove these superficial stains, leaving the tooth surface cleaner and brighter.

The other types of stains mentioned—such as deep-set stains and intrinsic stains—are not typically addressed by coronal polishing. Intrinsic stains are located within the tooth structure and often require different treatment approaches, such as bleaching or restorative procedures, to correct. Since coronal polishing is not designed to penetrate beyond the enamel and into the deeper layers of the tooth, it cannot effectively treat intrinsic stains. Thus, the focus of coronal polishing remains on the removal of only extrinsic stains.
