What type of stains are effectively removed through coronal polishing?

Coronal polishing is specifically designed to remove extrinsic stains, which are surface stains that occur on teeth due to various factors such as dietary habits, certain beverages (like coffee and tea), tobacco use, and poor oral hygiene. These stains are typically found on the enamel surface and can be addressed through mechanical means, like the use of polishing cups and pastes that provide the necessary abrasiveness to effectively clean the teeth.

Extrinsic stains are usually external and can often be removed without the need for invasive procedures. Coronal polishing techniques leverage that characteristic, helping to restore the tooth's aesthetics and improve its overall appearance.

On the other hand, intrinsic stains originate from within the tooth structure, often resulting from factors such as genetics, certain medications taken during tooth development, or conditions like fluoride staining. These stains are more resistant to routine cleaning methods and require different treatment approaches, such as whitening procedures or other restorative techniques.

In summary, while coronal polishing is excellent for maintaining oral health and enhancing the appearance of the teeth by eliminating extrinsic stains, it does not effectively remove intrinsic stains.
