Food stuck in empty wisdom tooth socket?

I got my four wisdom teeth extracted yesterday and this morning I was trying to eat scrambled eggs and got a piece of egg stuck in one of my bottom sockets. How do I get it out? I tried rinsing with warm salt water and it didn't come out but I'm worried that I'll dislodge the blood clot if I rinse too vigorously. Can this cause an infection? What can I do to get it to come out without harming the healing process?
