GUM Expanding Floss 2030 A new innovative floss that expands to thoroughly and gently remove plaque from between both tight spaces and wide gaps. Ideal for people with tooth and/or gum sensitivity and gum recession. Thin and easy to insert. Initially compressed and lightly waxed making it easier to insert between tight spaces. Expands during use. Moisture and friction cause the floss to expand allowing it to spread across the tooth and cover more tooth surface. Expansion reinforces a job well done and makes flossing fun! Gentle on your gums. Texturized nylon fibers are soft and comfortable to use. 32.8yd
