What is the expected outcome when coronal polishing is performed correctly?

When coronal polishing is performed correctly, the primary expected outcome is enhanced aesthetics and reduced bacterial growth. This procedure effectively removes plaque, extrinsic stains, and biofilm from the surfaces of the teeth, resulting in a brighter, more aesthetically pleasing appearance. By eliminating these deposits, coronal polishing also contributes to a healthier oral environment as it reduces the overall bacterial load in the mouth. This decrease in bacteria helps to lower the risk of dental diseases such as gingivitis and periodontitis, although coronal polishing is not a treatment for existing tooth decay or gum disease.

While the other options may seem appealing, they do not accurately represent the direct results of coronal polishing. The procedure is not designed to treat or alleviate tooth decay directly, nor does it provide long-term protection against gum disease. Although it may contribute to better overall oral health, it is part of a broader oral hygiene regimen that includes brushing, flossing, and regular dental check-ups. Additionally, coronal polishing does not typically reduce treatment costs, as it is one component of preventive dental care rather than a cost-saving measure in itself.
