Whole Foods Market Dedham and Radius Toothbrush are hosting a swap!  Bring us your current toothbrush and take home a brand new Radius Toothbrush for free!  Limit 1 per customer, 4 per family/group.  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.
