What the record tells you

David W Engen DDS Ps is an NPI registry record for a dental organization at 6817 N Cedar Rd Ste 202 in Spokane, Washington 99208. CMS issued NPI 1265642375 on 23 May 2007, and the practice last updated its own entry on 19 March 2015. That was 11 years ago, so treat the phone number and the suite number as unconfirmed until someone answers. CMS records it as a subpart of Darwin W Engen DDS Ps, so billing and pricing may follow the parent's policies.

It is registered under 3 dental taxonomy codes: Dentist (122300000X), Periodontics (1223P0300X), Orthodontics and dentofacial orthopedics (1223X0400X). That puts it in 3 categories on this site, led by periodontics. A practice that registers more than one category is telling CMS it does more than one kind of dental work at this address, which is why it has a page here rather than a row. No other address in the registry carries this name, though a practice trading under a chain brand often registers each office under its own legal name, so check the brand as well. 6 other dental records share the street address: Ola J. Englund, D.D.S., P.S., Mary Krempasky Smith, DDS, PLLC and Charles L. Regalado.

Spokane holds 200 registered dental practices inside the Spokane-Spokane Valley, WA area, which has 314 in total on the Washington side and ranks 2nd in the state. 5 of the Spokane records also register periodontics, so this is one of several local options in that category. Across the metro the mix runs general dentistry 56.4%, dental clinic or center 25.5%, orthodontics 7.6%. The closest other registered practices are Ola J. Englund, D.D.S., P.S. (0 miles, Spokane), Mary Krempasky Smith, DDS, PLLC (0 miles, Spokane) and Charles L. Regalado (0 miles, Spokane), with 2 more inside 0 miles.

On our figures a routine adult cleaning in Washington runs $120 to $180 cash and scaling and root planing $190 to $300 per quadrant, against a US average of $125. This practice's own prices are not in the registry and never will be: NPPES holds identifiers, not fees. Call (509) 326-4445 and ask for the cash price on code D1110, whether the exam and X-rays are included, and whether they run a membership plan if you have no insurance.

What to ask when you call

  1. The cash price for D1110, a routine adult cleaning, and whether the exam (D0120) and X-rays (D0274) are inside or outside that number.
  2. Whether you need scaling and root planing before a routine clean, and the per-quadrant price for D4341 or D4342 if so.
  3. Whether they run an in-house membership plan, and what it covers against what it costs a year.
  4. Whether they are taking new patients and how far out the next hygiene appointment is.
  5. The practice license, with your state dental board. An NPI is a billing identifier and proves nothing about licensing.

Where this comes from

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. This page describes a registry record. It is not a review, an endorsement or a check on David W Engen DDS Ps.

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. Treat them as a starting point and call two or three offices for an actual quote.
