 in the oral cavity. The rubber dam is held over individual teeth or groups of teeth by appropriate rubber dam clamps or threads (ligatures) along the edge of the gum. The tooth crown stands out from the rubber dam through individual holes made by a hole punch. This permits a clean and dry operative field, retracts the lips and cheeks, and enables treatment of the appropriate tooth without contamination from blood or saliva. Another function of the rubber dam is to protect the patient's airway from any materials which may fall into it during treatment.
