Which of the following is a potential consequence of not using an appropriate polishing agent?

Not using an appropriate polishing agent can indeed lead to damage to the teeth or gums. Polishing agents that are too abrasive can remove enamel, leading to increased sensitivity and a higher risk of cavities due to thinner enamel. Additionally, inappropriate agents can irritate gum tissue, resulting in inflammation or recession over time. The role of polishing agents is to smooth the tooth surface while preserving protective enamel; therefore, selecting the right agent is critical in maintaining oral health and preventing potential harm to the dental structures and soft tissues.

While enhanced enamel strength and better patient comfort might seem like benefits of certain agents, the focus of the question is on the consequences of misuse. Reduced time spent polishing, although potentially appealing, is not necessarily a safe outcome if the polishing agent used is inappropriate, as the priority should always be on safely maintaining dental health rather than efficiency at the cost of safety.
