On Earth, you brush your teeth with a toothbrush and toothpaste. This is not a big deal on Earth, but in space, that are two things to keep up with. However, having a toothbrush and toothpaste connected is a whole lot easier. I introduce to you the Tooth Cleaner 3000. All you have to do is fill up the dispenser with toothpaste, and when you want to brush your teeth, place the toothpaste directly on the toothbrush. The dispenser can also lock, so it won’t get in the way of brushing your teeth.
