Looks like you are having 'pericoronitis' which is basically inflammation of the gum around an erupting tooth. Because it is swollen you are unable to close your mouth properly wherein the upper tooth is impinging on the lower swollen gums.
Next Steps
Get an x Ray to see if there is space for the wisdom tooth to erupt completely. Get a laser gum removal done which removes the excess gum around the erupting tooth. Laser helps in faster healing and is comparatively painless.
