An elongated, slot-like recess communicates with the rear face and extends towards the front face from near the first end to near the second end. A method of securing a dental rubber dam clamp includes placing the cushion over at least one inside edge of the clamp and securing the clamp on a tooth so a portion of the cushion is compressed between the inside edge of the clamp and the tooth.
