What is coronal polishing primarily used for?

Coronal polishing is primarily used for enhancing the esthetics of teeth. This procedure involves the use of a soft rubber cup and a polishing agent to remove extrinsic stains and plaque from the enamel surface of teeth. The goal is to create a smoother, shinier surface, which not only improves the appearance of the teeth but also aids in maintaining oral hygiene by making it more difficult for plaque and stains to accumulate in the future.

While other options refer to important aspects of dental care, they do not align with the primary purpose of coronal polishing. Removing cavities is a restorative procedure that requires more invasive techniques than what is involved in polishing. Strengthening enamel pertains more to dental treatments involving fluoride or sealants, rather than a polishing technique. Improving gum health focuses on periodontal care and the overall management of gum disease, which is separate from the aesthetic focus of coronal polishing. Hence, the primary aim of coronal polishing is indeed related to enhancing the esthetics of the teeth.
