Answer 1

The correct technique for using a rubber polishing cup is to direct it toward the gingival third and press gently against the tooth surface, minimizing the risk of injury.

Step-by-step explanation:

When using a rubber polishing cup for dental procedures to avoid injury, the correct method is to direct the cup toward the gingival third and to press gently against the tooth surface. The proper technique ensures that the soft tissues are not damaged and that the tooth enamel is not excessively worn down. This approach minimizes the risk of causing harm to the patient's gums and teeth while improving oral hygiene effectively.
