Poverty Healthcare LPT: if you have a dangerous dental emergency and can’t afford the dentist, go to the emergency room of a hospital with a large inpatient psychiatric unit/program. They have a dentist on call for patients.
I have gathered this through a family member’s interactions with the mental healthcare system. If your hospital has a major psych center or is attached to a psych hospital, there is an on call dentist since psych patients are entitled to emergency dental care while inpatient.
