RADIUS was founded on the Caribbean island of Tortola. James O`Halloran and Kevin Foley were architects who were fascinated by the idea of a functional and enjoyable toothbrush. They were appalled at the small head, hard toothbrushes of the day. Research indicates that the major problem in oral hygiene is that of compliance -people don`t use toothbrushes for long enough and tend to keep their toothbrush for too long. Dentists believe that with diligence - teeth and gums could be perfectly maintained for a lifetime. The averageÂ brushing time is from 31 to 65 seconds, depending on age or sex. The average toothbrush is thrown away after 10 months. RADIUS aimed to make the toothbrush comfortable,enjoyable and effective. With a mass of very soft bristles, a large head area for low pressure brushing and a comfortable handle, this toothbrush would let you brush lightly and accurately.
