You can't really put much of anything down the glottis that you don't want to end up in the lungs...so..just scrape what you can ...treat the gum and palet area with whatever antiseptic you are using and get him on some antibiotics asap. That's about all you can do. If he can't eat and has lost weight, he will need to be tube fed for awhile till his teeth grow back. He will likely need to be tube fed water too unless he is drinking on his own...Usually with severe mouth problems like this...they just let themselves waste away and die. You can help him though and unless he already has massive organ dammage from other infections, he should recover fine...just hang in there.
