If there is a dental school in your area, or in a nearby city, they often have clinics where people can receive
dental care at low
cost. If there is a hospital in the region that has a medical school, you might call the medical school and ask if they had any dental clinics. Alternately, if there are any low-cost medical clinics in your city, you could ask them if they know of any source for low-cost dental care.
I hope you find a way to get your teeth taking care of soon. Feel better.
