Probably: In a city the size of richmond, va there should be resources to assist you in getting the treatment you need either free or at greatly reduced prices. Start with your local health department since some have dental clinics there. Also, your oncologist may be aware of dentists or dental clinics where services are provided on a "sliding scale" based on ability to pay.

Free: No one can afford to work for free all the time. That said, there are many social service dental clinics, especially in larger cities, as well as University Dental Schools, that offer significantly reduced rate treatment as tax supported programs and/or contributions help defray costs. Many practitioners also offer reduced fee or pro-bono treatment. You'll have to do some asking around.
