1. A powered dental floss comprising:
- a hand grip provided with an output shaft having a longitudinal axis, said hand grip incorporating a motor and a drive mechanism powered by said motor to cause said output shaft to vibrate along said longitudinal axis;
a floss connected to said output shaft and stretched to extend in a direction substantially parallel to and in alignment with said longitudinal axis so as to be driven by said output shaft to vibrate in that direction.

Abstract
A powered dental floss includes a floss and a hand grip provided with an output shaft which has a longitudinal axis and to which the floss is coupled. The hand grip incorporates a motor and a drive mechanism which is powered by the motor to impart a vibrating motion to the output shaft. The floss is stretched substantially in parallel with the longitudinal axis of the output shaft so that it is driven to vibrate along its length for effectively cleaning between the teeth.

4. A powered dental floss comprising:
-
a hand grip provided with an output shaft having a longitudinal axis, said hand grip incorporating a drive mechanism powered by a motor to cause said output shaft to vibrate or rotate about said longitudinal axis; an attachment carrying a floss and being detachably connected to said output shaft, said attachment including a motion-converting mechanism which converts the motion of said output shaft about its longitudinal axis into a vibrating motion of said floss in a direction parallel to said longitudinal axis of said output shaft.

8. A powered dental floss comprising;
-
a hand grip provided with an output shaft having a longitudinal axis, said hand grip incorporating a motor and a drive mechanism powered by said motor to cause said output shaft to vibrate along said longitudinal axis; a floss connected to said output shaft and stretched to extend in a direction substantially parallel to said longitudinal axis so as to be driven by said output shaft to vibrate in that direction; a load detector which monitors a load being applied to said motor and provides an output signal indicative of said load being monitored; and a controller which, in response to said output signal, varies an operational speed of said drive mechanism in order to correspondingly change the vibration rate of said output shaft.
