How can I get my top side button to work?

Hi everyone! On my Moto G, my top right button (the button that turns the screen on and off, it's also the power button) seems to be stuck. It doesn't stick out like it did when I bought the phone. I dropped it, and apparently the phone fell on or near this button. It is to the point now where I have to press this button just right for the screen to turn on, and it takes forever. Any help or suggestions would be greatly appreciated! Thank you in advance!
