My iPod Touch fell out of my pocket a few months back and i just noticed that the screen is popping out?

My earbuds caught on a cabinet door knob and my iPod hit the floor, the screen luckily didn't crack, but i just noticed that the screen is slightly popping out on the top right side. Should I bring it to Apple or will it probably not be a problem? And is there any way i could push it back in?
