I've found that by getting my adult male out of his enclosure and out into the front yard for exercise for about an hour every other day really helps with the pushing. His face wasn't as messed up as your girl's face but it was definitely a problem.

Also Vetericyn gel reduces the swelling if it's caught early. I spray a bit on my finger and then rub the gum line with it. My retics really hate that so it's a bit of a battle to apply it, but it does work.
