Dental health is significantly important when you get up in the morning or after a meal. However in process of brushing your teeth, foreign substances and tooth pastes that are left between your toothbrush hair could negatively result having a bad dental health. These substances can not be easily washed off by simply using water or rubbing it by your fingers. So we applied a one touch pump-action method in order to inflate the toothbrush head like a balloon This method extends the distance between hairs of the toothbrush, making it easier to clean.
