Horizontal Black Line in XR, should I replace screen?

So long story short, I dropped my XR screen first, tempered was a lil cracked, and a thin horizontal black line appeared. It kinda thickened after hours. My question is, will the black line dissapear by itself as time pass? I saw a reddit post that said after a month the line dissapeared, should I wait?
