Causes of a Dental Abscess. The cause of these dental abscesses is direct growth of the bacteria from an existing cavity into the soft tissues and bones of the face and neck. An infected tooth that has not received appropriate dental care can cause a dental abscess to form.
How fast does the international space station travel?   The International Space Station travels in orbit around Earth at a speed of 17,500 miles per hour (that's about 5 miles per second!). This means that the Space Station oâ¦rbits Earth (and sees a sunrise) once every 92 minutes!  .
Astronauts are by far the fastest traveling humans with the earth as a stationary reference point. One might think the Apollo missions to the moon are the fastest traveling humans, but the speed of that spacecraft was only about 6,300 miles per hour. In fact, an orbiting space shuttle is much faster at 17,600 miles per hour. This is the fastest any man has reached. Although it seems very fast to us, this speed is 0.026% of the speed of light. For unassisted speed using Usain Bolt's time in the 100 meter, his top speed is 23.3 miles per hour (10.4 m/s).
