Coronal polishing primarily involves the removal of which type of stains?

Coronal polishing primarily involves the removal of supragingival extrinsic stains. These stains are found on the surface of the teeth above the gum line and are typically caused by dietary factors, such as coffee, tea, tobacco, and certain foods. They can accumulate on the enamel and contribute to aesthetic concerns for patients.

During a coronal polishing procedure, an EFDA uses a polishing cup and a rubber or silicone point with a polishing agent to effectively remove these stains, providing a clean and polished surface that not only improves the appearance of the teeth but also helps in maintaining oral hygiene. This is especially important for enhancing the overall health of the oral cavity and preventing the buildup of plaque and calculus that can lead to periodontal issues.

Other types of stains, such as intrinsic discoloration or subgingival extrinsic stains, typically require different approaches, such as more invasive procedures or specific dental treatments, to address effectively.
