The Reach full head toothbrush features a cleaning tip, and blue outer bristles that highlight the bi-level bristle design. Longer, blue outer bristles remove bacterial plaque along the gumline while the shorter inner bristles clean plaque from tooth surfaces for an effective overall clean. The Reach toothbrush with its unique angled neck and tapered head is designed to clean the hard-to-reach places in the mouth. Features include: 1. Unique Power Tip helps clean behind front teeth and hard-to-reach back teeth. 2. Polished, end-rounded bristles help protect tooth enamel and gums. 3. Rubber grip on handle provides maximum control when brushing. (Dental professionals recommend replacing your toothbrush every 3 months.)
