Abstract
Abstract A flossing device is provided having a handle with a pair of resilient arms. Fingers extend from the arms and the longitudinal axes of the fingers form an angle of between 30° and 180° with each other. Each finger has a knob at its distal end. A length of flossing material is provided which is connected at each end to a grommet so that the flossing material and grommets can be readily attached and detached from the device. A safety strand is also provided which resists cutting of the user's gums by the flossing material.
