County-level dental access in Kentucky from public datasets: dentists per resident, Medicaid dental locations, health center sites with dental NPI matches, oral surgeon practice addresses, and drive time from Lexington to each county seat. Prepared September 17, 2026; source data retrieved July 2026.
59 health center sites have dental NPI address matches in NPPES (40 with multiple NPIs, 19 with a single NPI); additional sites remain unverified. No matching oral surgeon practice address was identified in this NPPES extract for 86 of Kentucky's 120 counties. These are registry findings, not a census of services — every figure carries its source, method, and limits under Sources & Method.
Dentists per county: County Health Rankings & Roadmaps 2025 (University of Wisconsin Population Health Institute), Kentucky data, Dentists measure; underlying source HRSA Area Health Resources File / NPI file, data year 2022. Downloaded July 20, 2026. Population: Census Population Estimates, 2023 vintage, as published in the same release.
Medicaid dental locations: federal InsureKidsNow.gov Medicaid/CHIP dental locator, queried July 20, 2026 — all 120 counties × all 6 KY Medicaid/KCHIP dental plans; 2,303 plan listings de-duplicated to 883 distinct practice locations. Every record returned carried an update date of April 21, 2026, so the counts reflect plan submissions as of that date. An access indicator drawn from what each MCO submitted to the locator, not a census of enrolled dentists.
Drive times: OSRM road-network routing (OpenStreetMap) from a fixed point in Lexington to each county seat (Census 2023 Places Gazetteer coordinates), computed July 2026. One estimate per county: it is the drive to the county seat, not to any individual clinic or practice shown in that county. Where a county has two seats, Alexandria (Campbell) and Independence (Kenton) were used. OSRM durations run roughly 5–15% longer than typical-traffic estimates, so the drive times shown lean slightly long.
Health center (FQHC) sites: HRSA Health Center Program — Service Delivery and Look-Alike Sites file (data.hrsa.gov), downloaded 2026-07-22. 671 active Kentucky records less 35 administrative-only offices = 636 sites from 35 organizations, including 28 FQHC Look-Alike sites. Contact details are exactly as published by HRSA — none are inferred; HRSA regenerates the file daily, so confirm before relying on them. The file lists sites of ALL service types and carries no service-line data.
Health center dental programs (organization level): HRSA Uniform Data System (UDS) awardee profiles (data.hrsa.gov Program Data), reporting years 2020–2024, retrieved July 22, 2026 — "Dental Patients" per organization. ⚠ Organization-level only, used here to show whether an organization reported dental patients and how many. It is never attributed to an individual site: an organization with a dental program delivers it at a subset of its sites, and HRSA publishes no per-site service data. "No dental program reported" means zero dental patients in the UDS years cited; current absence has not been verified. UDS dental is largely preventive and general dentistry — it is not evidence of surgical capacity (extractions under sedation).
Health center dental NPI matches (site level): NPPES NPI Registry read API v2.1, retrieved 2026-07-27 — 139 distinct dental-taxonomy NPIs whose registered practice-location address matches an HRSA FQHC site address, across 18 organizations. 40 sites with multiple dental NPIs matched (2+ at the address) · 19 with a single dental NPI matched · 537 with no dental NPI matched (unverified) · 40 with no dental NPI matched whose parent organization reported zero dental patients in UDS 2020–2024. A registry match supports further investigation; it does not establish that a dental program is currently operating. A site with no match stays unverified — absence of an NPI is absence of evidence. ⚠ NPPES addresses are self-reported: checked 2026-07-27 against HealthPoint Family Care's own dental-locations page, its three published dental sites returned 10, 6 and 6 NPIs while a fourth address returned 1 and is not on that page — hence the two tiers. A dental NPI indicates a dentist registered at the address, not an operating program, and says nothing about hours, Medicaid acceptance, or surgical capability.
Oral & maxillofacial surgery: NPPES NPI Registry, taxonomy 1223S0112X, statewide, retrieved 2026-07-27. The extract holds 228 NPIs with a Kentucky practice-location address at 134 distinct addresses (NPIs matching Kentucky on a mailing address only are excluded). 223 NPIs at 130 addresses are mapped, in 34 of Kentucky's 120 counties; 4 addresses (5 NPIs) at Fort Campbell could not be assigned to a county and are omitted — a military dental activity whose ZIP-code centroid falls in Tennessee. No matching oral surgeon practice address was identified in this NPPES extract for 86 counties. That describes the registry, not the ground: it does not establish that no visiting or otherwise unrecorded surgeon serves those counties. Locations geocoded via the US Census Geocoder; 14 placed by ZIP centroid where the address matcher had no record (marked "approx." in the tooltip). ⚠ PROVISIONAL proxy for surgical capacity: an OMS registration marks a surgeon's registered address, not a facility permitted for IV sedation. Kentucky requires a Sedation Permit Location Notification, so the Board of Dentistry holds the authoritative list of sedation-authorized locations; it is not published and requires an open-records request.
