What factor is pivotal in determining how often coronal polishing should be performed?

The frequency of coronal polishing is primarily determined by the individual's oral health status. This assessment includes factors such as the presence of plaque, tartar buildup, gum health, and any ongoing dental issues that may affect the patient's overall oral hygiene. Regular evaluations by a dental professional will reveal whether a patient requires more frequent polishing to maintain optimal oral health or if they are at lower risk and subsequent treatments can be spaced out.

In contrast, while the dental professional's preference may influence practices, it should align with the patient's needs rather than personal choice. A patient's ability to pay is certainly important for accessibility but does not reflect the clinical necessity for polishing. Additionally, the condition of dental tools is important for providing a safe and effective service; however, this factor does not directly dictate the frequency of coronal polishing relative to patient care. The priority in any dental procedure should always focus on the individual's health and well-being.
