When is it appropriate to use a rubber cup for polishing teeth?

Using a rubber cup for polishing teeth is most appropriately done for removing extrinsic stains when deemed appropriate by the hygienist. Polishing with a rubber cup is a technique used to enhance the aesthetic appearance of teeth by eliminating surface stains caused by factors such as food, drink, or lifestyle choices like smoking.

Hygienists assess each patient's individual needs and determine when polishing is necessary, considering the potential benefits and any contraindications specific to the patient's oral health. This selective approach aligns with best practices in dental hygiene.

Polishing is not routinely performed at every dental appointment, as this could lead to unnecessary enamel wear and potentially harm the tooth structure or gum tissue. It is also not strictly limited to cavity treatments or cosmetic procedures since its primary function is stain removal and enhancing oral hygiene. Thus, the context of use is crucial, reinforcing the importance of tailored dental care based on individual patient evaluations.
