This happened to my mum whilst in the care home, in fact it happened more than once and finally we lost them altogether. I'm sure you've done this already but it's worth asking the home's laundry, catering staff etc to check and double-check everything. Depending on the stage you're at with your dads dementia it may or may not be an option to get new ones. The problem is that if he's incredibly uncooperative he is unlikely to accept the intrusive process of being measured etc. If he can manage without then that's definitely your best option. Alternatively you could ask the home to bring more pureed food in to his diet. Good luck, MartinPlease can any one help. My dad has dementia. He is in a care home. He has lost his top set of dentures. No where to be found. He can be incredibly uncooperative. What can I do. He doesn't go out and doesn't have dentist.
