Hi, I'm a semi recent college graduate with very low income, I am a dog walker for a living :) I am struggling with deferring huge loan payments, and I have a huge amount of credit card debt

I cannot afford to get my cavities filled, and my whole mouth is rotting and only getting worse.  It's been years since I could go to the dentist. I'm wondering if there are any dentists with a good reuptation out there willing to do the necessary procedures at a very low cost or for free.  I'm also curious if anyone knows about dental offices with financial assistance available, or that are privately funded.  Any financial contribution towards getting cavities filled would also work, I just need help soon!  The pain is getting bad, not to mention I'm losing friends over the...bad breath side effects of so many cavities. 

Thank you for any support you can offer me!  Even advice! :)
