I've seen a tweeter dust cap massaged out with a finger before. The guy rubbed around the dent and it popped out. The dust cap on your woofer is probably thicker...
I have also heard of people using a vacuum cleaner. This can probably do more harm than good, though, unless you have an attachment with an adjustable vent so you can make the vacuum less severe.
Others will hopefully have some first hand experience to offer you. Good luck.
