Which area of a tooth is primarily polished during coronal polishing?

The area of a tooth that is primarily polished during coronal polishing is the coronal surface, specifically the enamel. This is because coronal polishing focuses on cleaning and smoothing the outer surfaces of the tooth, which are most visible and commonly exposed to the oral environment. The enamel, being the hardest and most protective layer of the tooth, benefits from polishing as it helps remove plaque, stains, and any debris that may accumulate on its surface, ultimately contributing to improved oral hygiene and aesthetics.

Polishing the coronal surface enhances the tooth's appearance and can also foster a healthier environment in the mouth by reducing the potential for bacterial growth that contributes to dental caries and periodontal disease. This practice does not involve the root surfaces, which require different techniques for cleaning, nor does it typically address interproximal areas or the gingival margin, which may require specific instruments or procedures for effective cleaning.
