      I think an actual astronaut may be better at showing you how this is done than me! Chris Hadfield who is an astronaut and spent a lot of time on the ISS has produced a lot of videos about how some of those day-to-day things are done in space and you can see how he demonstrates brushing your teeth in this video on YouTube https://www.youtube.com/watch?v=TU9kffoAQ8U He also explains that they more often swallow the toothpaste when they’re done! Brushing you’re teeth in space is one the things that’s more similar to how we do it here on Earth, (you can still use the same toothbrush and your favourite brand of toothpaste), but things can get more complex when you start thinking about showering or washing your hair, even going to the bathroom!
