When is a heavier rubber dam typically utilized?

A heavier rubber dam is typically utilized when better tissue retraction is needed. This type of rubber dam is designed to provide enhanced stability and support during dental procedures, which is crucial when there's a need to keep the operating area clear of saliva and blood. Effective tissue retraction helps in exposing the area being worked on, allowing for better visibility and access.

In procedures where the precision of the work is paramount, such as in endodontics or restorative dentistry, using a heavier rubber dam can make a significant difference by ensuring that the surrounding soft tissues are properly retracted and protected. This not only safeguards the tissues but also improves the overall efficiency and effectiveness of the procedure.

In contrast, during aesthetic procedures or routine examinations, a lighter rubber dam might suffice, as these situations often do not require the same level of tissue management. Oral surgery could involve different techniques and may not primarily rely on rubber dam usage for tissue retraction, focusing instead on surgical drapes and other methods suited for more complex interventions.
