Ottawa holds 9 of the 32 registered practices here (28.1%), ahead of Peru on 6 and Mendota on 3. 5 of the records are specialty practices rather than general dentistry or a general clinic, led by orthodontics. No practice here carries more than one dental taxonomy code, so every listing is a single-category office. The oldest NPI in the area was issued on 27 July 2006 and the newest on 17 June 2026; 18 records have not been updated since before 2020, so check the update column before you call.

CMS NPPES NPI data file, August 2026, snapshot 10 August 2026. US federal public data (FOIA-disclosable, no charge). CMS NPI files. NPI registry records, status as reported by CMS in the August 2026 data dissemination file. NPPES is an identifier registry, not a license register: an NPI does not validate that a practice is licensed, accredited or currently open. Practices maintain their own NPPES entries. Every page shows the date the record was last updated; addresses and phone numbers are as self-reported and are not verified by us. Metro boundaries are the 2023 Census CBSA delineation, joined by the county of each practice address. File published 10 August 2026.
Price figures are our own, last verified April 2026. State averages are our estimates compiled from FAIR Health regional cost data and CMS Medicare fee schedules; the ADA discontinued its national Survey of Dental Fees in 2023, so no national fee survey exists.
