A 2008 meta-analysis of whether oral irrigation is beneficial as an adjunct to tooth brushing concluded that " the oral irrigator does not have a beneficial effect in reducing visible plaque ", but suggests it may be beneficial to gingival health in addition to regular tooth brushing. A study at the University of Southern California found that a three-second treatment of pulsating water (1,200 pulses per minute) at medium pressure (70 psi) removed 99.9\% of plaque biofilm from treated areas.
