The service you've probably heard about is affiliated with the University of Mississippi Medical Center's School of Dentistry, and I'm not sure what baseline you have for the typical cost of care for a 'regular' dentist. All services offered in association will be of top quality care.
The University of Mississippi Medical Center sponsors and hosts many outreach efforts to improve health of the local community. This facility offers services mainly related to medical care, but not dentistry. You can read more about the UMMC's oral care. You can call to make an appointment at 888-815-2005 or make an online appointment request.
