I had mine out, it wasn't all that bad. It's been several decades, but I don't think I was all that sore - I remember going shopping the next day. They were badly crowding my other teeth - in fact, my front teeth are still seriously out of alignment and wearing badly because we waited too long to have the wisdom teeth out. But I'm not sure they were actually termed "impacted." It's better to have it done early than to wait. They're still trying to figure out how to fix my teeth - I also should have had full braces forty years ago, but, oh, well. Cheap parents.
My daughter, however, had hers out when she was in high school and they were definitely impacted. She was very sore for three or four days - looked like a chipmunk from the swelling for the first day. But after a week she went back for a recheck and she was already healing very well. They did hers all at once under general anaesthesia. She was "out" for less than 15 minutes, came home two hours later.
I'd suggest cold soft foods - your sorbet - for a day or two, then other soft foods. Oatmeal, scrambled eggs, pasta, milkshakes.
Good luck!
