Which of the following is a contraindication for routine rubber cup polishing?

Decalcified areas represent a contraindication for routine rubber cup polishing because these areas are often weakened and may be more susceptible to damage during the polishing process. The abrasive action of rubber cup polishing can further compromise the integrity of enamel that has already been compromised by demineralization. This can lead to discomfort for the patient and potentially worsen the condition of the teeth.

In contrast, healthy gums indicate that there is no active disease present, and minor dental issues may not significantly affect the safety of polishing. Standard teeth can typically undergo polishing without concerns. Thus, it’s critical to recognize that any undermined enamel due to decalcification can lead to further complications if subjected to this type of polishing. It is essential for dental professionals to identify and avoid polishing in areas where the enamel is already damaged to maintain optimal oral health.
