Barb, (TomM) If his tongue is thick in size it could be from fluid retention (edema). some mornings my speech is affected by swelling. It goes away by mid-day.

Brian's comments are true but consider that the visable signs of thrush are what a person with normal saliva exhibits. Sometimes in the radiation affected mouth, thrush does not show anything to be scraped off.

Mark, 21 Year survivor, SCC right tonsil, 3 nodes positive, one with extra-capsular spread. I never asked what stage (would have scared me anyway) Right side tonsillectomy, radical neck dissection right side, maximum radiation to both sides, no chemo, no PEG, age 40 when diagnosed.
