What is the proper angle for the polishing cup during application?

The proper angle for the polishing cup during application should be almost in contact with the tooth. This positioning allows for effective removal of any surface stains and polishing of the tooth surface without causing damage to the enamel. By maintaining close contact, the polishing cup can apply optimal pressure and engage effectively with the tooth, promoting a smooth finish while ensuring patient comfort.

If the polishing cup is placed at a perpendicular angle or parallel to the tooth surface, it may not efficiently polish the teeth or could lead to uneven polishing results. A 45-degree angle might feel comfortable but doesn’t ensure sufficient contact to achieve the desired polish. Thus, maintaining the cup almost in contact with the tooth is crucial for effective polishing in dental procedures.
