White Coating In Mouth

I was hit in the mouth with a softball and my teeth cut the inside of my upper lip very deep, I did not go to the hospital because I wanted to wait until tomorrow. I think his recovery, but it has this white coating on it. Is this good or bad and what should I do about it

you are who is the crust like you would get a thin white skin on any cut, it also happens in your mouth so I would leave him alone and let it finish healing, even if they are fun to play with, but leave it alone and you can even gargle with salt water, if you want to avoid being contaminated
