Brushing in space may have one or two differences with the ground. The main difference is that in space, there is no place for "tiny". So everything has to be edible. When an astronaut brushes his teeth, he must swallow toothpaste. That is why their toothpaste is made edible. Then the toothbrush is cleaned with a few drops of water and then dried and returned to its place.
