Use this when the user in a US state looks for low-cost or free dental care. Returns verified routes: dental schools (name, city, URL, check date), health centers and dental shortage-area (HPSA) designations, Mission of Mercy events and charity programs, with an optional county for the dental-desert atlas row. Dental-school clinic fees are not published by Real Dental Costs. Phrasings: "where can I get dental work on a tight budget in Columbus", "dental school clinics that see patients in Ohio", "¿dónde hay dentistas gratis en Illinois?", "clínicas dentales de bajo costo en Franklin County". Also use it when the user asks whether their county is a dental shortage area or where the community health centers are. Every figure carries its source URL and period; a missing cell returns status no_source_at_this_level with the next level up. Medicaid amounts are what Medicaid paid per claim line (T-MSIS), not what a patient is charged. No personal data (age, ZIP, name, insurer) is requested or stored. Do not use for: diagnosis, treatment choice, a named insurer's plan price, dentist recommendations, countries other than the US and Canada. Observed market research, not a quote, not medical, coding or insurance advice.
