• The root of the tooth, generally located beneath the gum line, also does not undergo coronal polishing; the focus is primarily on the clinical crown for this procedure.

• Alveolar bone is part of the jaw structure that supports the teeth and is not subject to coronal polishing, as this area is not pertinent to the aesthetic or preventive polishing of the teeth.

Thus, the focus of coronal polishing being specifically
