Home remedies for an abscess tooth?

i have had a bad tooth for over a year and a half... i only have like half of a tooth. top right side of my mouth, i was having a horrbile toothache the other night so i went to the hospital, they gave me pain pills and anit biotics. the day after my face was huge swollen, last night i went to a different hospital and they gave me different(stronger) anti biotics and more pain killers... today, my face is STILL swollen, looks like i have a black eye, ANDDD now a blister thing on my gums(abcsess?) i have tried using a needle to pop the blister thing, but it hasnt worked. i have been taking my anti biotics and putting an ice pack on my cheek, and rinsing my mouth out with salt water alot all day long, but my face is still swollen. i have an interview tomorrow morning, and i need to know what to do to make my face not so swollen. just until i can get into a dentist.
