The dental dam has a thin elastomeric web portion which overlies a portion of the patient's face and which may be punctured to allow one or more teeth to protrude through the web. The dam also includes a plastic frame which is integral with the web at the periphery of the web. The frame can be bent to conform to the shape of the patient's face and will retain its bent configuration during subsequent use of the dam. After the dental procedure involving the dam is completed, the dam, web and frame, are discarded.
