How can astronauts brush their teeth
The first is to chew the special chewing gum with the function of cleaning teeth directly after meals;
The second is that the fingertip made of sterile gauze is coated with special edible toothpaste. When brushing teeth, the astronauts put the fingertip on the index finger, squeeze the toothpaste on it, and replace the toothbrush with fingers, and eat it directly after brushing.
yes! Also eat toothpaste!
Brushing your teeth, which seems to be a very simple operation on earth, has become a rather troublesome thing in space. Every wrong step will cause a chain reaction and even endanger the lives of aircraft and astronauts.
