Dear Dummie whose name is not worth scrolling up to see,
Call your area dentists and ask if they know of any dentists doing charity work, DUmmie or not it should not matter. I know of a guy in Terrell who would pull a tooth for $10 when he is doing charity. He is in an impoverished region of Brazil at the moment being a missionary and working on third world teeth.
Check around the clinics, check large area churches.
If its as bad as you say, start calling around.
Thank you for your support,
FGL
