When using a rubber polishing cup, how should it be directed in relation to the gingival third?

When utilizing a rubber polishing cup during coronal polishing, it is important to direct the cup away from the gingival third of the tooth. This technique helps prevent potential trauma to the soft tissue of the gums, which can occur if the polishing cup makes contact with that area. The gingival third of the tooth is sensitive, and applying pressure or directing the polishing cup towards it can lead to irritation, recession, or even damage to the periodontal tissues.

By directing the rubber polishing cup away from the gingival third, practitioners can effectively polish the enamel without compromising the health of the surrounding gingival tissue. This approach not only promotes a healthier environment for the gums but also allows for a more effective cleaning and polishing of the tooth surfaces, contributing to better overall dental hygiene outcomes.

It's crucial to maintain this technique consistently to ensure that coronal polishing is both effective and safe for patients.
