Rinser Brush
From the department of How Did No One Think of This Before, we bring you the Rinser Brush ($22). This ingenious toothbrush sports a built-in scoop that funnels water to a small hole on the top, creating an instant fountain for rinsing out your mouth — hence the name. Features include a button to control the fountain, a no-nonsense design, and GreenerStep Snap replacement heads to ensure that the brush stays useful way after its first bristles are shot.
