Shane,

My elderly father died recently (after a stroke rather than oral cancer) but he was under hospice care. He did stop eating but would sip a little water and died within a week of stopping eating. He became agitated and confused at times and I have known this to happen to others as they neared the end. He did receive anti-anxiety medicine when he became agitated and that helped a lot and helped his loved ones as his agitation was distressing. My thoughts are with you as I cannot even imagine how difficult it is for you to have both parents in the dying process.
