Bedridden mother w/dental issues

Hello. I care for my 89 year old mother who has severe Alzheimer's and has been bedridden since falling and breaking her hip in February of last year. She has visiting hospice nurses twice a week, and (by the grace of God) is doing well, overall for her circumstances.

My Mom has a full upper partial, which had previously been held on by two teeth, both since broken off, and now hangs loose in her mouth. By the grace of God, she is still able to eat and has a good appetite.

Her bottom teeth have been rotting for the last year or so. I noticed them just prior to her fall (Feb. 2024), and she had an appointment to see the dentist the day after her fall — an appointment we had to cancel as she was in the hospital, and has subsequently been bedridden.

I brush them the best I can (she doesn't cooperate) three times a day (but w/o toothpaste, as she can't spit in bed).

Over the past few months, her rotted bottom teeth have been breaking off, and she looks as if she was hit in the face with a sledge hammer with a row of jagged, broken, mostly missing lower teeth.

Just today I noticed something askew. She has a solitary tooth with broken (mostly missing) teeth on either side of it. It is leaning (tilted) way forward.

The way it's bent, it won't likely break off like the others, but the way it's leaning, I don't see how it's not going to come out of the socket entirely -- which would be a nightmare, as she'd be bleeding, and I'd have no way to stop it.

With her Alzheimer's she has no understanding and can't follow directions, and I wouldn't know what to do. I can't believe there are zero options for dental care for persons with Alzheimer's who are bedridden. Like the hospital which didn't feed her at all for the nine days she was a patient, it's clear that the medical community (if not every part of our culture) doesn't care about people with Alzheimer's.

I know there's no human resolution to this, and I'm only writing this out of desperation, but it's a shame there is nothing humanly possible to help her. I've reached out to everyone I can locally, every agency, everything available. There is no human help. None.

God help my mother, because no one else can. :(
