2 of my kids have been through this. one had all 4..the other 2. whatever you do...keep it packed!!! watch for dry socket.
don't drink from straws. don't talk too much. (sistermoney got dry socket. she was a college senior..had no choice to talk. had a big project due)
soft over cooked veggies. baked sweet potato. mash up what you can. it sucks, but both my kids were back to eating regular foods in less than 2 weeks.
