What effect does using a rubber dam with too small of holes have on the gingival tissues?

Using a rubber dam with holes that are too small can lead to increased trauma to the gingival tissues during dental procedures. When the holes do not adequately accommodate the teeth and surrounding structures, the dam may exert unwanted pressure on the gums. This pressure can cause irritation, inflammation, or even injury to the soft tissues, resulting in discomfort or pain for the patient.

Additionally, the improper fit may restrict the clinician’s ability to see and manipulate the treatment area effectively, potentially leading to more aggressive handling of the tissues to compensate for the lack of space. Therefore, a properly sized rubber dam is crucial for protecting the gingival tissues and ensuring patient comfort during dental procedures.
