For which type of patients should coronal polishing be approached with caution?

Coronal polishing should be approached with caution for patients with weak or demineralized enamel because their enamel is already compromised and more susceptible to damage from abrasive polishing techniques. In these cases, the use of polishing agents can potentially exacerbate the condition of the enamel, leading to further loss of mineral content and increasing the risk of cavities or sensitivity.

Patients with braces often require coronal polishing but usually benefit from it as it helps to remove plaque and stains around brackets, although care must be taken to avoid damaging the braces or surrounding tissues. Patients with comprehensive dental hygiene typically maintain good oral health, which might reduce the need for coronal polishing altogether. Therefore, the priority should be on protecting the integrity of weak or demineralized enamel, as it is more vulnerable to damage.
