Help with a toothache?

I went to my orthodontist to get my wire changed in my braces. The hygienist had to get a spring in my mouth to lift up a tooth over another one. She had to push really hard on my tooth and it really hurt. She usually does that alot and it doesnt hurt as much. But this time its really hurting me. Please give some advice on how to ease some of the pain and make it feel a little better. Thanks :) <3
