As all the rinsing mugs are used for rather long time, scale and toothpaste will gather at the bottom of the mugs. The mugs then become a hotbed for the dirt which will spread diseases instead of helping cleaning the mouth. How to deal with cumulative dirt, most of the people will choose to ignore because of their not paying enough attention and their fear of troublesome. By changing the bottom structure of the toothbrush and not increasing any cost, Brush-TWO provides people a faster and more convenient way to clean the dirt of the mugs. That is the innovation of Brush-TWO.
