I dropped my phone in a toilet a few months ago,

i dropped my phone in a toilet a few months ago, andi dried it immediately, and it worked fine the same day. but a few days later, the screen started to flicker black, and now the screen doesnt appear at all anymore. its been a few more months. i can still call people, but canttxt because of the dark screen. is there any way i can fix the screen with the silicon baggy things, after its been so long?
