GUM Professional Clean Flossers have easy-to-control and ergonomically shaped handles preloaded with GUM dental floss, which has a satin-like finish that is extremely soft and gentle and resists shredding, breaking and sagging. The floss easily slides into position under the gumline and then removes the dental plaque not removed by regular toothbrushing. Between-teeth cleaning is recommended by dentists and dental hygienists to remove dental plaque between the teeth where toothbrushes alone cannot reach.
