How often should coronal polishing be performed on a healthy patient?

The frequency of coronal polishing on a healthy patient is best determined by personalizing the approach to each individual's needs, which is why "as needed based on assessment" is the correct answer.

Coronal polishing is a procedure designed to remove plaque and stains from the tooth surface, promoting oral health. Assessing each patient allows the dental professional to consider factors such as their oral hygiene practices, the presence of any periodontal issues, and their overall dental health. In some cases, a patient may not require coronal polishing at every visit if they maintain excellent oral hygiene and have minimal plaque buildup.

This tailored approach ensures that the procedure is beneficial and not unnecessarily performed, as excessive polishing can lead to enamel erosion or dentin exposure over time. Regular assessment allows the hygienist to determine when coronal polishing is appropriate, promoting a more effective and patient-centered approach to dental care.
