    • A light electric dental flosser with a rechargeable battery compartment includes a motor casing, interchangeably individualized head units, and disposable plastic floss tips that snap mount within the hinged end of the head unit. The floss tips exhibit bidirectional flossing motion provided from a motion translation system including an eccentric cam, a yoke, and an output shaft with a cam follower mechanism that follows a generally Z-shaped tracking surface with a vertical track component and a horizontal track component enabled by the yoke to complete the resulting "Z" movement. The floss tips have a molded-in filament and are molded from a shock absorbing substance which absorbs the vertical component of the "Z" shaped motion upon the application of pressure to the filament thereby outputting horizontal motion until the filament passes through the contact area between two teeth. In an automatic mode, an infrared sensor in the head activates the motor when the line of sight between infrared sensors is broken by the filament approaching a contact area between two teeth.
