Reducing swelling after wisdom teeth extraction?

I had four wisdom teeth removed about 55 hours ago (Thursday morning). It seemed that my swelling was worse yesterday and has decreased a bit today, but I'm having some mixed messages on what I can do to continue the reduction of swelling. I've been taking two tablets of Dexamethasone for swelling (one in the morning and one at night) and one Hydrocodone about every 6 hours for pain. These were both given to me by my oral surgeon. I'm also taking some natural distress drops. The pain really isn't bothering me but I was wondering how to reduce the swelling some more. I pretty consistently used ice for the first 40 hours while awake and now some research on my own is telling me to use moist heat, and I'm hearing from other people that heat only made the swelling worse or did nothing at all. Should I be rinsing with salt water? Or taking some ibuprofen? Thanks!
