Improved dental floss dispensers that impregnate floss with fluids and/or solids have been developed. One dental floss dispenser consists of a tube (12) that holds a roll of dental floss (11) separated from the main chamber (16) by either a disc or a bag. The main chamber may consist of one or several compartments (16a, 16b) and it is filled with fluids and/or solids. The untreated floss is first threaded through a hole (19) in the protective cover (13) that separates the floss reel (15) from the lower compartment (16a) and it passes through the lower compartment filled with a viscous fluid of sufficiently high viscosity. The partially impregnated floss is then threaded through a barrier (14) that divides the lower and the upper compartments (16a, 16b) and passes through the upper compartment (16b) filled with an impregnating fluid or solid. The fluids and/or solids are now adhered to the floss so it can be used as a means to deliver compositions. The impregnated floss is then threaded through a hole (21) in the closure of the dispenser and it is sealed by adhesive backed plastic, paper or foil (23). A cutter (26) is placed on the neck of the container (12) and it is used for removing a segment of the impregnated dental floss.
