DANB Coronal Polishing Practice Test

Using too coarse of a polishing paste can indeed damage the enamel surface and increase sensitivity. This is because a coarse paste contains larger abrasive particles that can create micro-abrasions on the enamel. These micro-abrasions compromise the smoothness of the enamel, leading to a rougher surface.

When enamel is damaged, it can result in increased exposure of the underlying dentin, which is more sensitive to temperature changes and external stimuli, potentially causing discomfort or increased sensitivity in the tooth. Additionally, the roughened enamel can attract plaque and stains more readily, further exacerbating oral health issues.

This highlights the importance of selecting an appropriate polishing paste that balances effective cleaning without compromising the integrity of the enamel.
