My wife is a year and a half into reconstruction, so she has gone through this on multiple occasions.
You should be given eating instructions by the dentist. It helps is you get the instructions before the procedure so you can get the right food ahead of time while you are feeling better.
The instructions should also tell you what not to eat and for how long.
In my wife's case she was limited to clear liquids for the first few days. She relied a lot of bottled bone broth. She would mix bottled broth with frozen cubes of home made broth to add more flavor.
There is an Ensure that is clear but you have to make sure you get the right one. Also, Gatorade and jello.
After this initial post-surgical period she was limited to soft food. I gave her a soup maker for Christmas a couple of years ago and she would make some excellent vegetable soups, such as potato leak (or fennel) and tomato, often with vegetables from our garden.
If you have bone grafts then you will have stitches. It is real important that you don't do anything to harm the stitches. Her oral surgeon tells the story of a guy who ate a chocolate chip cookie and screwed up $10,000 of work.
He ended up adding chocolate chip cookies to his list of foods not to eat.
Good soft foods to start with are apple sauce, jello, pudding, mashed potatoes. Soft white fish like tilapia is great when you get to the point where you can handle it.
I just finished cooking tilapia for my wife.
My wife is nearing the end of her process. What she can eat depended on the work that had been done and the state of her mouth. It is now about what she is able to eat. We cooked a turkey and pork meatloaf, which she could handle.
After you get past the initial healing period then it is about what you are able to eat with the missing teeth.
When her work is done she should be able to eat anything.
