55.7%
of records are in Roseville
Roseville holds more than half of the county total. Auburn's rate is much higher than the other five communities, so counts and rates tell different parts of the local picture.
Placer County · provider records and access indicators
Placer County dentists, compared community by community
Roseville has the largest provider count, but Auburn has the highest recorded rate in the entire 18-county footprint. That rate reflects Auburn's smaller population as well as its 59 provider records.

Where records are located
Provider records are concentrated unevenly
The bars compare active NPI-1 records per 10,000 residents. A higher registry rate does not establish shorter waits, broader insurance participation, or more available appointments.
Population scope
Who is included in the population rate?
The six tracked communities represent nearly three-quarters of Placer County residents. Mountain and untracked communities remain outside the calculation.
The numerator and denominator cover the same named communities. Using the full county population with this partial location count would understate the rate.

- Outside the denominator
- 115,684
What this rate cannot establish
The calculation does not measure appointment capacity, patient travel, office hours, insurance participation, or dentists who serve county residents from another city.
Specialty record
Which dental specialties appear?
All six specialist groups appear. Orthodontics leads the specialist count, followed by periodontics and endodontics.
These categories come from provider-selected NPPES taxonomies. They are not a count of specialists accepting patients.

Questions about the report
How to read the Placer County figures
How many dentist records are in Placer County?
Placer County has 415 active NPI-1 dental-provider records across the 6 communities in this report. This is a count of individual federal registry records, not dental offices or available appointments.
Why does this report use named communities instead of the full county?
The provider records are assigned to practice-location cities. The rate therefore uses the combined population of those same 6 communities: 319,139 people, or 73.4% of the county estimate.
How many dental practices does the directory cover in Placer County?
The directory currently has 140 published practice profiles across the communities in this report. Practice profiles and NPI-1 records are separate measures because one office may include several dentists.
Does an NPI record mean a dentist is accepting patients?
No. An active NPI record supports provider and practice-location analysis. It does not establish appointment availability, hours, prices, insurance participation, or whether the dentist still works at that address.
What does a dental HPSA designation show?
A federal dental Health Professional Shortage Area designation identifies a geographic area, population group, or facility that meets HRSA shortage criteria. It is a separate measure from the provider-record counts on this page.
