Sometimes their jaws get kinda crumpled when feeding and sometimes they strike and hit something like the glass or bulb cage and get kinda knocked out of place temporarily ... pretty sure they dislocate their jaws as well at feeding time so it could be any of the above ..

I've read of some Retics who get their jaws a bit crumpled by pressing their faces against the sides trying to get out of their enclosure - they also resolve themselves after a while when changes to the enclosure are made ..
