Nancy,
This makes me so angry. You are the daughter, you are next of kin. Power of attorney doesn't mean you have no say in matters. As for missing dentures, they often end up on the food tray and down in the dietary dept., kitchen or are thrown out. So are glasses. sometimes too, they are wrapped up in the sheets or blankets and end up in the laundry. At any rate, the home is responsible and most often is held accountable. A missing items report should have been filed and they should be doing something about it. Not only the Ombudsman should be involved. Again, I say, talk to the social worker AND/OR the administrator. I don't know about there - here I would call the Department of Publis Health if I was not getting the right answers from the people at the home. The family members that speak up get the most results. Talking to a lawyer is also a very good idea.
