I need some help with finding a dentist or a free clinic badly!!!!?

I've had horrible teeth my whole teen and adult life, mainly because of being in states care and to the living situations, I am covered by medicaid, and it doesnt pay for dental, and my credit is bad so i cant get the "care credit" for the dentists office. I need a surgical full mouth extraction, and dentures to go with. So if anyone knows of any free or reduced or charity care programs in the OK or North TX area that would be greatly appreciated.

Check out local universities. The usually offer reduced dental fees. You'd see a dental student but they are highly supervised.
