I know this question has been posted but I need suggestions for 97 year old who is very alert and physically capable. OMG, I'm not talking spitting. This is horking up loogies and spitting all over the place. He claims he's spitting in the toilet, but he's not even in the bathroom. I won't allow anyone in the area without shoes. OMG...and the smell. He does not have Alzheimers or dementia. He's just a pig. He refuses to brush or clean his mouth. I work in dental so it's insulting, but...whatever. Sometimes I wish I could just let him sit in all the filth, but it doesn't bother him. Home Health has come 3 x week for months and he refuses to bathe and they can't force him. We've tried acting like it's a prize, we've been stern...nothing. I know it's crazy. I already feel better by just having said this. Any suggestions?
