What the record tells you
North Seattle Periodontics is an NPI registry record for a dental organization at 1222 N 185TH St Ste 102 in Shoreline, Washington 98133. CMS issued NPI 1013865070 on 17 March 2026, and the practice last updated its own entry on 17 March 2026. That is recent, so the contact details are likely to be current. CMS records it as a subpart of Nagatomo & Chen DDS MSD PLLC, so billing and pricing may follow the parent's policies.
It is registered under 3 dental taxonomy codes: Dentist (122300000X), Periodontics (1223P0300X), Prosthodontics (1223P0700X). 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. One other dental record shares the street address: Yen-Wei Chen PLLC.
Shoreline holds 42 registered dental practices inside the Seattle-Tacoma-Bellevue, WA area, which has 2,421 in total on the Washington side and ranks 1st in the state. 1 of the Shoreline records also register periodontics, so this is one of only a handful of local options in that category. Across the metro the mix runs general dentistry 54.4%, dental clinic or center 25.9%, orthodontics 6.9%. The closest other registered practices are Yen-Wei Chen PLLC (0 miles, Shoreline), Highland Dental Center (0.1 miles, Shoreline) and Hooe & Ryskalczyk PLLC (0.1 miles, Shoreline), with 2 more inside 0.2 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 (206) 953-5799 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 North Seattle Periodontics.
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.
