I think my cheeks went down fully...er unpoofinized, after about a week...or a few days more than that. Some people's turn solid greenish-yellow, mine just turned slightly off tint. They werent sore, but the back of my mouth really hurt, along the jaw line.
I just advise taking the pain killers whether you think you need them or not, and have a cup for blood the entire first and second day (some need it, some dont...I sure did).
I now remember what it was like to not be able to close my mouth. I was so happy when my molars touched for the first time after the surgery
As much as I didnt enjoy it, at the time, Id have to say that it was my best medical-mouth ordeal (yes better than just regular stuff)
