Our data
Contribution: derived analysis, downloadable dataset
- Collected: 20 practices with a SmilesAtlas profile (general and pediatric dental practices whose own website or Google listing says they take emergency, same-day or walk-in patients), joined to the NPPES registry, the Dental Board of California license roster, their Google listing and their own website. Observed: NPPES registry file 2026-09-27; Dental Board of California roster 2026-06-10; Google listings 2026-06-07; practice websites read 2026-08-24.
- Published: 26 counts for this page; practice-level facts stay on each practice's profile and on the official sources.
- Computed: 4 derived shares, each with its formula and arithmetic in the dataset.
- Method: a practice is verified when all four fields pass: a dentist at the practice matched by license number and listed as active by the board, an NPI, a practice ZIP matching its Google listing, and one fact the practice publishes itself. Verified means the records match; it is not a rating. A practice is listed here when its own website says it takes emergency, same-day or walk-in patients, or its Google listing carries the category “Emergency dental service” or “Walk-in clinic”; either says the practice takes emergencies, not that it has an opening today. A website that names only same-day crowns, implants or appointments does not count. How we verify.
