.We all know that astronauts need perfect vision to explore the space. Did you know that they should have good oral health, too? That’s right: astronauts need good teeth!
According to European Space Agency officials, this is “because the acceleration forces and vibrations during a flight into space can be very strong”. These acceleration forces can be up to 4x the body weight of an astronaut. This pressure is sufficient to make hidden cavities and inflamed dental pulps (tooth nerves) very painful. The vibrations are strong enough to dislodge crowns, bridges and fillings from teeth. Without easy access to dental treatment in space, astronauts need to have excellent dental health before being cleared for lift-off.
