An ultrasonic manipulator of dental floss is provided with an ultrasonic mechanism and a floss creep controller mechanism to enable periodic floss creep during use and a reverse of creep upon a tension designation. A process controller controls floss driving and an eccentric mechanism, and a user pause function allows a stop of floss motion and a locking of drive motors to allow floss to resist undue stress and to minimize damage to drive mechanism.
