Question

astronaut if you have fillings from cavities?

Answer 1

Fillings can trap air in the dental work. At the low air pressures found at high altitude this trapped air can expand and cause great pain, or pop the filling out or even crack your tooth. So fillings are a disqualifying condition for any military pilot. And all astronauts must pass a military flight physical. My father applied to be a military pilot, but he had fillings in all his teeth. They told him he could fly if he had all his teeth pulled out, but he didn't want to fly badly enough to do that.

Answer 2

Astronauts and fighter pilots all live in pressurized suits or environments.
A great reduction in pressure would prevent them from utilizing oxygen efficiently and reduce performance.
Consider the number of airline passengers that fly at reduced pressure with no ill effects.

I spent the past four days basically scourging the internet for this question in my free time. If you go to http://astronauts.nasa.gov/ and use the websites search engine you will find tons of results that I couldn't find at all through Google or anything else.

Here are a couple of the ones I found the most interesting
