What is a primary benefit of coronal polishing for a patient's oral health?

Coronal polishing is primarily beneficial for a patient's oral health because it effectively removes plaque from the surfaces of the teeth. This removal is crucial in preventing dental caries (cavities) and periodontal disease, which can lead to gum infection and tooth loss. By smoothing the tooth surfaces and eliminating plaque buildup, coronal polishing helps in reducing the bacterial load in the mouth, thereby contributing to overall oral hygiene.

While increasing tooth sensitivity, replacing lost enamel, and acting as a whitening treatment could be associated with different aspects of dental care, they do not accurately reflect the primary purpose of coronal polishing. The focus here is on preventive measures that maintain and improve oral health through plaque removal, making this a key aspect of routine dental care for patients.
