What are some signs that a tooth surface has been properly polished?

A properly polished tooth surface should exhibit a smooth, shiny appearance that indicates effective removal of plaque and stains. This shiny finish results from the interaction of a polishing agent with the tooth enamel, leading to a reflective surface that is aesthetically pleasing and contributes to the overall health of the tooth. Additionally, the absence of residual paste is essential as remnants can lead to plaque accumulation and potential gum irritation.

The other options represent outcomes that do not meet the criteria for effective polishing. A dull, rough texture or any residual paste signifies insufficient polishing, while a matte finish with slight abrasions suggests that the polishing process may have damaged the enamel rather than enhancing it. Furthermore, a fuzzy texture and decreased sensitivity indicate that the tooth surface is not in an optimal state and may require further treatment. Thus, a smooth, shiny surface with no residual paste is the hallmark of successful coronal polishing.
