A dispenser (10, 80, 110) for dental floss comprises a closed container having a reel of dental floss (24) disposed therein, and having a generally planar back face (14), a front face (12), a pair of opposed side faces (16, 18), a top face (20), a bottom face (22) opposed to the top face, and a corner at each intersection of the top and bottom faces with the pair of opposed side faces. A hub (40) is centrally located in the interior of the closed container and extends between the interior surfaces of the front and back faces. The reel of dental floss is mounted for rotation about the hub. There is an opening (44, 130) in either the front face or the top face at a first corner of the container, through which a strand of dental floss (42) extends so as to be unwound from the reel; and a friction and cutting member (50) is at a second corner of the front face or top face. The friction and cutting member comprises a tongue portion (52) which is angled away from a base portion (54). The front or top face is concave on an axis (25) extending perpendicular to the first and second corners of the container, the concavity being defined by ridges formed in the face at the first and second corners. A channel (70, 132) is formed at the second corner, and is positioned such that the dental floss extends from the opening at the first corner through the channel located at the second corner.
