Do you think you can handle space oral hygiene?

Brushing our teeth is important because it saves us from having cavities and tooth decay. Here on earth, we can simply spit the mouth foam on a sink while we are brushing teeth but it is not the same case with astronauts. They are not allowed to spit because those liquid can enter the engines of their ship. So they have 2 choices, it is either to swallow the toothpaste, saliva and water concoction or spit it in a paper towel. I use to dream of becoming an Astronaut. Oh they can't take a shower so they just clean their body with baby wipes. No wonder astronauts don't have sex in space. They are too grossed out with their hygiene issues.
