Depending on the type of paint (some has oil), and how much went into the well, and assuming you didn't clean it out, and then filled it, well, it's a minor risk indeed, but seriously, why would you play with an exposed fill nipple? You'll get dirt and all manner of crud in there at the very least, and that's no good.
Haha I had to play all day without one because mine fell in the dirt...
