Touch Bar stopped working after water damage

I have a MacBook Pro (13", 2018) with a touch bar. I accidentally dropped a bit of water on my touch bar and it stopped working. It's been that way for a while now. I tried opening the activity monitor to see if it pops up like how it does for the others, but nothing related to the touch bar is appearing to me. However, the fingerprint sensor still works. How can I make the rest of the touch bar function again?
