Is coronal polishing after scaling necessary?

Based on the indexed literature, coronal polishing after scaling is not considered a routine necessity for all patients.

The current view is that polishing should be done selectively based on patient need rather than as a universal component of prophylaxis ^[1]. Overzealous polishing can wear superficial tooth structure, promote local deposit accumulation, and delay reformation of the fluoride-rich enamel layer ^[1].

From a clinical outcomes perspective, the Cochrane review found little or no difference in gingivitis, probing depths, plaque, and oral health-related quality of life between patients receiving routine scale and polish versus no scheduled treatment over two to three years in adults without severe periodontitis ^[2]. The rapid review similarly concluded there is no evidence that dental polishing specifically is effective ^[3].

When polishing is performed, prior plaque disclosure has been shown to significantly improve plaque removal effectiveness regardless of the polishing modality used, and air polishing required less treatment time than rubber cup polishing ^[4].

In summary, the evidence supports selective polishing based on individual patient need rather than routine coronal polishing after every scaling appointment ^[1], and any decision should incorporate clinical judgement about the patient's risk profile and periodontal status ^[3].
