What the record tells you
Mountain Smiles, PLLC is an NPI registry record for a dental organization at 727 Trail Rd in Sedro Woolley, Washington 98284. CMS issued NPI 1326844564 on 19 February 2025, and the practice last updated its own entry on 27 February 2025. That is recent, so the contact details are likely to be current.
It is registered under 7 dental taxonomy codes: Dentist (122300000X), Dental anesthesiology (1223D0004X), Endodontics (1223E0200X), General practice dentistry (1223G0001X), Periodontics (1223P0300X), Prosthodontics (1223P0700X), Orthodontics and dentofacial orthopedics (1223X0400X). That puts it in 6 categories on this site, led by general dentistry. 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. The record also carries 122400000x, 124q00000x and 126800000x, which is a staffing signal rather than a service in its own right. The same registered name appears at 3 distinct addresses nationally. That is either a group practice or a name common enough that unrelated offices share it, so ask whether pricing is set locally or by a parent company. One further NPI is registered to what looks like the same business at this address (Atkinson Family Dentistry, NPI 1003014879); it is covered by this page rather than given a page of their own. One other dental record shares the street address: Atkinson Family Dentistry.
Sedro Woolley holds 8 registered dental practices inside the Mount Vernon-Anacortes, WA area, which has 77 in total on the Washington side and ranks 9th in the state. 7 of the Sedro Woolley records also register general dentistry, so this is one of several local options in that category. Across the metro the mix runs general dentistry 45.5%, dental clinic or center 29.9%, pediatric dentistry 6.5%. The closest other registered practices are Atkinson Family Dentistry (0 miles, Sedro Woolley), Glyn A. Fleury DDS (0.6 miles, Sedro-Woolley) and Sedro Woolley Family Dental Center, P.S. (0.6 miles, Sedro Woolley), with 2 more inside 0.7 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 (360) 856-4540 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
- The cash price for D1110, a routine adult cleaning, and whether the exam (D0120) and X-rays (D0274) are inside or outside that number.
- Whether you need scaling and root planing before a routine clean, and the per-quadrant price for D4341 or D4342 if so.
- Whether they run an in-house membership plan, and what it covers against what it costs a year.
- Whether they are taking new patients and how far out the next hygiene appointment is.
- The practice license, with your state dental board. An NPI is a billing identifier and proves nothing about licensing.
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 Mountain Smiles, PLLC.
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.
