Which statement describes how to protect gingival tissues during polishing?

• A. Aggressive rubbing near the sulcus
• B. No contact with the tooth
• C. Controlled adaptation avoiding the sulcus
• D. Using large burrs

Answer: (A)

Protecting the gingival tissues during polishing comes down to how you apply the polishing instrument to the tooth surface. Use controlled adaptation and keep the abrasive away from the gingival sulcus. That means applying light pressure and making careful, small strokes along the tooth surface while ensuring the cup or brush does not contact the sulcular area or periodontal margin. This approach minimizes heat, friction, and trauma to the gums while still effectively polishing the enamel.

Aggressive rubbing near the sulcus can injure soft tissue and generate heat, which risks recession or inflammation. Never polishing with no contact to the tooth would prevent removal of stains, and using large burrs isn’t appropriate for routine polishing and increases the chance of tissue trauma.
