B&W 601 dented tweeter repair?

well i finally let my guard down with my 2 year old. i left the speaker covers off for a couple of days and wouldnt ya know he pushed in the tweeter 1st chance he got, @#!% kids!

anyways, should i try to fix it with a vaccumm cleaner or something, or should i just leave it alone? it still seems to sound fine, but it really bugs me to leave it...
