Abstract: Rubber Floss is a dental floss made from rubber and sulfur. Rubber Floss is a material that would not come apart between the teeth like all other flosses that are woven together. Rubber Floss is soft and would not cut or hurt the gums as other flosses can do. The main advantage to using Rubber Floss is that once the floss is stretched out and placed between the teeth and the tension released it will expand and fill the gap between the teeth allowing the floss to clean away the food particles from both sides of each tooth. There is no other floss on the market that can expand and clean in this manner.
