Reach Advanced Design Toothbrushes are scientifically designed with a distinctive angled neck and tapered head to clean hard-to-reach places. These toothbrushes feature two-tiered bristles to help clean between teeth and along the gum line. The distinctive angled neck extends behind the back teeth 60% further than other main brushes. Reach Advanced Design toothbrushes also feature an ergonomic rubber grip for better comfort and control with brushing.
