For once, knowledge is making me poor!
Here is a "healthy" way to fix a ball mark.
The ball landing on the green compacts the sod and tears it backwards. Try to undo that damage by using a tee to peck deeply enough to restore the pushed and compacted sod back into place. This will avoid additional tearing and will aerate the area that has been compacted. Six or eight rapid pecks with the tee will usually restore it well enough that you cannot see the mark when done.
