A power driven dental floss holder for cleaning the teeth with dental floss is provided. The power driven dental floss holder comprises a power unit 14 on which is mounted an elongated vibratory arm 12 and an elongated nonvibratory arm 22 having dental floss 21 threaded in a triangular configuration between the distal ends thereof. The novel dental floss holder may be easily and quickly moved between the teeth to control the degree of vibratory motion imparted to the floss and therefore to tooth surfaces, thus minimizing the likelihood of injury to gum tissues.
