After placing a rubber dam, checking the fit and seal of the dam is crucial for ensuring effective moisture control during a dental procedure. A proper seal prevents saliva and other fluids from contaminating the working area, which is essential for maintaining a clean environment for dental work.

If the rubber dam does not fit snugly or there are gaps, moisture from saliva or other sources can compromise the procedure, potentially leading to increased discomfort for the patient or a reduced likelihood of successful treatment outcomes. By verifying that the dam fits correctly, the dental assistant helps safeguard the precision of the procedure and enhances patient safety.

While rinsing the area with antiseptic can help in maintaining cleanliness, it does not directly address the integrity of the moisture barrier provided by the rubber dam. Removing excess saliva can be part of the process, but it would be ineffective if the dam does not have a good seal. Applying dental wax can assist in creating a tighter seal in some cases, but it is not the first step that ensures the primary function of the rubber dam. Hence, the most appropriate immediate action is to check the fit and seal of the dam.
