Open Question: Is it okay to constantly brush your teeth to relieve pain and pressure?

Okay so this past Friday I got separators in on both sides of my first molars, top and bottom, to prep for my braces in 3 weeks and it hurts a decent amount as well as having pressure from them creating space all the time. I have this toothbrush that they gave me to use and so far it helps relieve the pressure and pain whenever I brush over them with it, so is it okay? If not, is there something I can do or use to help relieve the pressure and pain?
