So I accidentally dropped my Series S. What should I do?

It was on it’s black stand and I accidentally hit it and the xbox dropped. It slightly broke open but surprisingly it still plays the games I used to play without any noticeable glitches or lags. Do you think some damage was done inside? How do I get it back to it’s normal shape? I’m afraid it will start showing lags and glitches in the future because of this. Thanks in advance!
