If you sand down the neck, you will change the profile. People seem way to willing to sand away.
If it is an oiled neck, first thing to do would be to get a clothes Iron, a damp sock, and see if you can steam out the scratch/dent. I usually use a sock with distilled water. This will usually mess up the oil and wax finish a bit, but if you're going to redo it, that doesn't matter.
