Joice's Medical / Dental fund

Hello - My name is Joyce I am 81 years old and I have no dental insurance of any kind and my only means of income is Social Security, very low.  I havent been able to go to a dentist for 10 years due to no money.  I have asked serveral dentist in my area hoping that somehow they are able to help with a very big discount or even for free, but sinice I have no insurance or any money they are not able to help me, I have many days I am in so much pain I cant eat or sleep, Since there is so much work now needing to be done I will have to have surgery for the teeth before they can be redone.  Therefore, I am asking for some help and any help would be appreicated as I am suffering every day from severe toothaches. Or if you know of a dentist that would help me please let me know.
