Hi. I am answering this to bring it to the top again. I had the forearm flap to line the floor of my mouth, but I had a Peg tube.I was not allowed to eat by mouth for 6 weeks or more. The Peg is a great way to keep nutrition in your body while you heal. I am puzzled why Doctors are not giving Pegs to patients who have oral surgery of this level.Anyway maybe someone will see this again who has had your problem and answer.
