Abstract
A teeth cleaning device with a core pump area that provides positive pressure to push out water jetting streams and negative pressure to retract the floss attached to a piston, while the power input has enhanced torque due to the bevel gear structure; an optional spring may be placed inside the piston assembly to add to the reciprocating power, and thus creating more effective water jetting and floss oscillating motions for better teeth cleaning.
