I had all four wisdom teeth extracted on friday, all were non impacted. Two days ago I had a pizza and something got stuck in my wisdom teeth extraction hole, I can't see it because I can't open my mouth much but I can definitely feel it. I tried rinsing with salt water and using a syringe but neither worked. Both my cheeks were swelled since the day I had them extracted, but since this morning only the one with the stuck food is swelled, the other one is fine. Should I be worried?
