i used to as a child trim harrys, but he was a special case, being my soul mate in a hamster, he was so special to me.

placing a ceramic tile, a terracotta bowl or similar, can gently ease it down, i think pomice stones can also go in the cage, ild place these somewhere she will use often but not constant.
e,g
place her food bowl on a terracotta plate
or a tile under the water bottle

I have heard of sand inserts for wheels, but i think its not needed.
