An electric dental flosser apparatus includes a drive mechanism for rotationally oscillating a drive shaft 4 about its own axis and a floss holder 3 mounted on the drive shaft 4 so as to be oscillated rotationally by the drive shaft 4. A flosser element 5 is stretched taut on the floss holder in a direction perpendicular to an axial direction of the drive shaft 4 so as to pass across an extension line A of the drive shaft 4 or a position adjacent thereto.
