Ouch. Our son went through this a few years ago. If you have access to a blender, smoothies with yogurt, bananas and/or berries, and peanut butter are filling. Cottage cheese is good. Scrambled eggs or soft omelets. Soft pasta such as well-cooked mac & cheese once your mouth can handle it. Personally, I would go crazy on crusty pizza once all is healed. Feel better soon.
I had my wisdom teeth pulled a couple of years ago along with another tooth as well (5 in all). No fun and they bled for quite a while afterwards. Cool and creamy things really hit the spot like yogurt, smoothies, chocolate milk. Once they were a little less sensitive, I ate oatmeal with strawberry jam, and things like that, until I could start chewing again.
