I never got used to water flossing, how do you know where to aim it while it's in your mouth? Are you literally dragging the tip across your gum line? I always had trouble getting the proper angle (perpendicular to teeth) and then when it comes to the front teeth it's impossible to do behind them because the tips don't have enough of an angle to them and you're also shooting water everywhere.
