Dental Care For Low Income, Needed BADLY?

My mother has had bad luck with teeth. Currently she has no back teeth and a few of the teeth in the front. Out in 'smile view' on the bottom row and half that on the top. Since she cant eat very well shes lost A LOT of weight and she was already underweight to begin with. On top of that she's very conscious of them and it has been making her very depressed. We can't afford for her to get them all pulled, which they need, and dentures to replace them. Does anyone know of some Heath Aid that can help?

in my city, the university students do their final exams on low income people who have contacted them. maybe you could try something like that?
