A mouth dam formed by cutting, punching or the like, each mouth dam from a sandwich of sheets of a thin, highly absorbing material, which sheets may be coated with a surfactant and further may include a flavor impregnated therein. Each mouth dam is cut, shaped or otherwise formed to be sealed at its edges, to have a length to width relationship where the length is three to four times the width, the width of the mouth dam ends is greater than at its center and the mouth dam sides slope uniformly from the center to the ends with an open area as a reservoir between the sealed mouth dam edges. A preferred mouth dam of the invention has a width at its ends that is from one-quarter (1/4) to five-eights (5/8) of an inch and a length that is from one to one and three-quarters (13/4) inch.
