I busted my lip due to a fall and it is also swollen
If there are cuts inside your mouth, you can rinse then with salt water or a hydrogen peroxide solution - do not swallow the peroxide rinse. It may foam, which is perfectly ok reaction when the peroxide runs into bacteria inside the mouth.
To reduce the swelling, apply cold compresses and if you are bleeding, apply pressure with a clean cloth.
