what do you do when you can't afford more dental care?

I was very sick for a while and during that time pretty much everything crashed on me dental wise, and I already have $16,000+ in dental bills I put on the credit card, $2000 I haven't paid yet, and quite a lot more to go and things still look terrible. I don't know what I can do besides run my credit card up higher, and eventually I won't be able to do that anymore. any ideas? I'm on disability and Medicare has no dental coverage.

There are places like Social Services and if they can'y help then they can tell you who can. Call them first. Hope it helps. Jeremy
