Abstract: A coilable structure having segments of dental floss mounted thereon, in parallel, tandem arrangement, is stored in a housing. A spindle in aft chamber thereof is attached to one end of the structure (in this case, a tape). Rotating the spindle aftwardly advances the tape so that the next floss segment is placed on the top of a partition between the chambers, positioning the segment slightly above and between a fixed and a sliding top member of the housing, where it can be grasped by an applicator having a handle and a pair of resilient prongs with slitted shoulders on their ends for retaining beads on ends of the floss segments. Aftwardly-convergent guides on the sliding top member compress the prongs together, as they are moved aftwardly between them by a user, prior to grasping a floss segment. Aftwardly-divergent guides on the fixed top member allow the prongs to expand without losing the floss they have grasped, as aftward motion of the prongs is continued.
