My mom is 83, has severe dementia. She is very combative and non compliant to most of what I ask of her. I try to get her to sleep on her side, but sometimes she lays down on her back and nothing gets through to her. She has upper dentures and when she sleeps on her back, her mouth falls open and she snores a little and I'm afraid her denture might fall into the back of her mouth and block her airway. But asking her to give me her denture, or asking her to let me take it out is one more battle I don't want to fight if choking is not actually an issue to worry about. Thanks for your input.
