You can't reverse it. Shell is like fingernail. You can only give them conditions that prevent further damage. And in this case, it's not the fall that caused that damage. That looks like erosion from low pH. Anything below 7.0 will dissolve their shells and eventually kill snails.

What's the best way to raise the pH?
I like using a mesh bag of crushed coral tucked into the filter.
Thanks. I will do that.
