I worked as a Nurse's aide when I was in my 20's (needed timeout from the upholstery business). We had thefts amongst other residents. We had a "kidnapping" of a Lady's baby (one of those real looking baby dolls). I found her in another residents room. When I tried to take the baby home to her ""Mom", the Lady who had her yanked my ponytail
and brought me to my knees. All I could do was scream for help, that lady had a death grip on 4 feet of my hair and wasn't letting go!
There were other small thefts mostly brushes, eyeglasses slippers etc. But I don't ever recall someone stealing teeth.
