An apparatus for maintaining a dry field during dental procedures includes a tongue shield for holding the patient's tongue in a retracted position. Cheek distention arms extend laterally outward from the tongue shield to distend the cheek away from the teeth. Optionally, lip retractors extend from the cheek distention arms. Stanchions on the cheek distention arms can be used to removably engage the tip of a saliva ejector and thereby secures the position of the saliva ejector relative to the apparatus and the patient's anatomy.
