Senior with $20k+ med debt needs teeth

I'm a 66 y.o. single woman, disabled, in the midst of a series of medically needed podiatric surgeries. So far *ALL* 9 procedures done between 10/29/2014 - 11/2015 *needs* to be redone due to the Toms River DPM surgeon's shoddy abilities. So I face another 9, at least. Plus more: 4-5 that were never addressed. All feet problems stem ONLY from deformed flat feet, a congenital matter. No injuries, no accidents: just bad feet, that's all. So far, what's been done has put me into $20+k of new medical debt, so $20k of future med debt is awaiting. Plus, the exzisting med debt should have been less than $10k, but 'that' doctor f-ed-up so bad that two bunion ooerations turned into 3 re-repeats too.

I'm unable to work: disabled. I live alone (rent), with all of my funds depleted by medical problems of my diabetes that onset in 2007. Divorce in '06 (a 30 year marriage ended due to my depression problems; my spouse simply 'burned-out' disposing me as if I were a spent tissue!) left me without dental insurance, and I've been unemployable, disabled, since 2004. I need 19 extractions and dentures cost of which is $6700+. I can pay-off, over time, some of it, but certainly not all. So I seek help to put teeth back into my mouth. Right now I have just 5 left, and one is certain to fall out within days: it is already loose. I have no savings or assets, and no family to lean on. Can you help, please? I ask for a portion of the final amount, not all. That'd be "grubby" of me to do. Costs are SO high and my Social Security, a pension and some alimony don't go far enough to plan a $600/month payoff. So, please commit what you can spare.
