Here are a couple of suggestions from someone who has just been through something similar, the extraction of a lower wisdom tooth. The extraction was an emergency procedure, so I didn't have the luxury of shopping ahead for foods that would be acceptable, but I was lucky enough to have a decent stock of things that worked.
The first day: scrambled eggs with buttered bread. I wanted toast, but the sharp edges would have been dangerous. What I did was place one slice of bread on top of another, butter the upper slice generously, then pour about 1/4 to 1/2 cup of milk slowly over the bread so that it would soak in and soften it. When the eggs were ready, I turned them out of the pan onto the bread so that the heat of the eggs would melt the butter. Not bad. I also had ice cream and yogurt in the house, both of which the oral surgeon said would be O.K. as long as I made sure not to let any seeds or fruit bits migrate to the affected side of my mouth. Also, some juice. Tea.
The second day: I had a stuffed bell pepper (the filling was rice, onion, tomato, and bits of Italian sausage). I was careful to chew only on the other side of my mouth. More yogurt, more ice cream. How nice to have an excuse to eat more ice cream! Juice and tea.
Good luck! I feel your pain!
