Opening a dental practice in Colorado: the numbers

Colorado at a glance

Population growth, dentist density, and unmet dental-care demand are national percentiles computed across the counties nationwide that have a value for that measure: a county at the 90th percentile ranks at or above 90 percent of those ranked counties. Counties without a value are excluded from a ranking. Percentiles describe counties, not individual sites.

Counties with the lowest dentist-density percentile

These 10 Colorado counties rank lowest in Colorado on the national dentist-density percentile. Ties are ordered by higher population-growth percentile, then by name. No density value could be computed for 4 of 64 counties, so those are left out of this ordering.

No dentists could be allocated to these counties in the source data, so they have no density value: Cheyenne County, Costilla County, Jackson County, Kiowa County.

Counties with the highest unmet dental-care demand percentile

These 10 Colorado counties have the highest unmet dental-care demand percentile, derived from the share of county residents living in HRSA Dental Health Professional Shortage Area ZIP codes. Ties are ordered by lower dentist-density percentile (counties with no density value first), then by name. HRSA often designates whole counties, so 18 Colorado counties share the state's highest value; the table shows the first 10 of them in that order. 13 Colorado counties share the dataset's lowest value for this measure and are not listed.

Counties with the highest population growth percentile

These 10 Colorado counties have the highest population growth percentile in the dataset. Ties are ordered by lower dentist-density percentile, then by name.

The dataset has no county population field, so small counties can appear in either table; check county size before reading much into a percentile. A dash in the dentist-density column means no dentists could be allocated to that county in the source data (4 of 64 counties here).

Sources and method

• Median household income and county demographics: US Census Bureau American Community Survey 2023 5-year estimates.
• Population growth: US Census Bureau Population Estimates, 2024 vintage.
• Metro or non-metro setting: USDA Economic Research Service Rural-Urban Continuum Codes, 2023.
• Dentist density: public CMS NPPES provider-enumeration counts allocated to counties by land area and divided by ACS county population (dental provider records per 10,000 residents), converted to a national county percentile. NPPES enumeration is not licensure, credentialing, or verification that a dentist is practicing, so this is a density indicator, not a count of active clinicians.
• Unmet dental-care demand: HRSA Dental Health Professional Shortage Areas (2026-Q3), measured as the share of county residents living in shortage-area ZIP codes (US Census ACS population), converted to a national county percentile.

The county dataset was compiled September 30, 2026 (vintage acs20235-pep2024-rucc2023-hpsa2026Q3-nppes202608). This page was generated September 30, 2026 directly from that dataset. Every figure is read from the named public datasets or is a count, minimum, maximum, or sort over them; no composite score or ranking formula is applied on this page. Tables are sorted on the named measure, with ties ordered by the stated secondary ordering and then county name. County equivalents — such as Alaska boroughs and census areas, Louisiana parishes, independent cities, and Connecticut planning regions — are counted as counties. Full layer-by-layer provenance is in the evidence and coverage ledger.

This is public context for a county, not a site recommendation. It does not measure competing offices at an address, payer mix, lease terms, or patient demand for a specific practice.
