GUM® Eez-Thru® Comfort Slide Flossers have easy-to-control and ergonomically shaped handles preloaded with GUM® Eez-Thru® dental floss made with a special PTFE nonstick material. GUM® Eez-Thru® dental floss has a satin-like finish that is extremely soft and gentle and resists shredding, breaking and sagging. The PTFE-coated string floss easily slides into position under the gumline and then removes the dental plaque not removed by regular toothbrushing.
