What is one characteristic of a good polishing agent?

The characteristic of a good polishing agent that stands out is its ability to not cause excessive wear on the tooth surface. This is crucial because the primary goal of coronal polishing is to remove plaque and stains while preserving the integrity of the enamel. If a polishing agent were to wear down the enamel, it could lead to a range of dental issues, including increased sensitivity and a higher risk for cavities.

In the context of patient care, maintaining healthy tooth surfaces is a top priority, which is why using a polishing agent with minimal abrasiveness is emphasized in dental hygiene practices. Other factors such as cost, flavor, and the need for professional experience certainly play a role in the overall dental practice environment, but the safety and effectiveness of the polishing agent in protecting tooth enamel is paramount.
