It happens when the travelers are getting into such places and conditions when they do not have the opportunity even to get a bathe or brush their teeth. For those who spend a lot of time traveling and wants to be fresh, special toothbrushes, named toothettes were invented in the USA. You don't need water at all to use them. The toothpaste that is already in the brush is activated when saliva contacts the brush. Of course, toothetes do not brush the teeth so carefully as normal toothbrushes, but sometimes they seem to be just indispensable. |
