Because they can't hop in the car and go to the doctor's office if they get sick, and there is no ambulance in space if they are injured.
what astronauts do to keep their mouth healthy is to brush their teeth obviously (and what do suits have to do with your mouth) NOTHING!

The term "artificial gravity" refers to using science technology to create gravity. This is usually desired by astronauts and space organizations such as NASA to keep their astronauts healthy and to minimize the effects of weightlessness on astronauts during long term space travel.
By thorough training, education, and healthy lifestyles including good nutrition, exercise and relaxation techniques such as meditation.
Because teachers can be in the astronauts and they learned about astronauts and they went to the astronauts team.
Astronauts keep healthy in space by exercising regularly to prevent muscle and bone loss, following a balanced diet to maintain their nutritional needs, and staying hydrated. They also undergo regular medical check-ups and participate in scientific research to study the effects of space on the human body.
Without gravity, food aromas waft away before making it to the nose. When you cannot smell very well you can't taste very well. And because of the fluid shifting to the head, astronauts' nose will be stuffy. Astronauts have to maintain a balanced and healthy diet that prevents them from losing weight.

No astronauts have died on the moon. All astronauts who have traveled to the moon returned safely to Earth.
Astronauts need to know chemistry to understand how different materials and substances behave in the unique environment of space, such as changes in temperature, pressure, and radiation exposure. This knowledge is essential for the maintenance and operation of spacecraft systems, as well as for performing experiments and research in space. Understanding chemistry also helps astronauts stay safe and healthy while living and working in space for long durations.
