How quickly can wisdom teeth move?

Yeah, another question about wisdom teeth. :)
My dentist says there isn’t a huge rush to take out my wisdom teeth, even though they’re almost touching my back molars. They’re coming in at an angle, so they’ll just push the molars out of the way. This is more than a cosmetic problem.
The insurance is dragging their feet about authorizing the procedure, so I’m in this for the long haul.
The family dentist looked at my X-ray and said it’ll be months or years before damage is done. I find this hard to believe, considering the pain I’m in. I saw the X-ray myself, and it sure looked to me that the wisdom teeth were just about touching the molars, already.
My mom and I were thinking about getting a second opinion. Would it help?
How quickly do wisdom teeth actually move?
Is a space of approximately a millimeter or two considered by dentists a large space?
How quickly could a wisdom tooth move approximately 1–2 millimeters?

Thanks, everyone.
