The one percent Hydrogen Peroxide won't cause any infections and won't cause any serious problems, if you remember to follow up with plain water.
However, it may not whiten your teeth very much. The Hydrogen Peroxide solutions used for that purpose are at least 3 times as strong (3% solution), and sometimes they are as much as a 15% solution.
But if you want to experiment, go ahead. It won't hurt to try.
