Abstract:

A dental flosser includes a housing having a pair of arms spaced apart to define a gap therebetween, a supply core rotatably coupled to the body, a wind-up spool rotatably coupled to the body for rotation in a single direction with respect to the body, a pawl movable between an engaged position that restricts rotation of the supply core with respect to the body assembly, and a disengaged position that allows the supply core to rotate with respect to the body. The flosser also includes an actuator operatively coupled to the pawl and the take-up spool. The actuator is operable to move the pawl from the engaged position to the disengaged position and to rotate the take-up spool in the first direction.
