Abstract

An improved oral irrigation technique is characterized by an oscillatory swept water jet issued to sweep back and forth at high frequencies across the user's gums and teeth. High frequency operation is achieved by oscillating the jet itself rather than the jet-issuing body. The high frequency sweeping jet effects faster cleaning action and more effective gum massage than prior art pulsed jet irrigators having lower effective operating frequencies.
