How to get rid of abcess infection after tooth removal

[DallasAliceFromDownTheHole]

I had my third molar removed through emergency dental surgery two days ago, thankfully.  My jaw swoll up to the size of a grapefruit going down my throat and into my ear with a red discoloration on my skin, very angry like with heat and a lot of severe pain.  The dentist misdiagnosed my problem, thinking it was an impacted wisdom tooth.  Two days later my face was disfigured and I was in the ER getting antibiotic iv's and morphinr for pain.  Since then, the tooth was extracted.  However, no drainage was preformed.  Leaving the grapefruit on my face.  Now, I'm sick as a dog in all the infection.  How can I get through this quicker and safely?  In gargaling slightly with warm salt water.  Rinse and spit frequently.  And on antibiotics.  The extraction site is all white looking like infection so I'm not sure if that's the blood clot or if its infection clot.  The infection keeps swelling up on my face, then will drain continuously.  But it never acts like its going all the way away..but more like playing tag.  Come and go.  I can feel it swell back up.  Eww..  Can I do anything to stop this?  Gargle with peroxide?  Listerine?  Or just keep doing what I am with warm salt water and take my pills?
