The present invention relates to a dental cleaning device, particularly to a flosser device for cleaning teeth gaps. The flosser device according to the present invention removes food particles from different tooth gaps by mounting the flosser element to the flosser element longitudinal connecting slot and the flosser element transverse connecting slot to adjust the position of the flosser. The flosser element base is disposed in the gradually narrowing flosser element connecting slots, so that the flosser element arms diverse outwardly to tension a length of flosser between the flosser element arms. Besides, the center of the flosser element connecting slot is hollow to form a base receiving hole so that the base press-release point projects through the base receiving hole out of the handle after the flosser element base is mounted on the flosser element connecting mechanism, and a user can draw out the flosser element by pressing the base press-release point for replacement.
