What the record tells you
Dunn Orthodontics, the trading name of Az Sds II LLC, is an NPI registry record for a dental organization at 3409 N 56TH St Ste C in Phoenix, Arizona 85018. CMS issued NPI 1619719036 on 7 June 2024, and the practice last updated its own entry on 7 June 2024. That was 2 years ago; the details are probably current, but confirm the address when you book. CMS records it as a subpart of Az Sds II LLC, so billing and pricing may follow the parent's policies.
It is registered under 2 dental taxonomy codes: Orthodontics and dentofacial orthopedics (1223X0400X), Pediatric dentistry (1223P0221X). That puts it in 2 categories on this site, led by orthodontics. 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 same registered name appears at 4 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. 3 other dental records share the street address: Dental Design of Arcadia, Az Cosmetic & Family Dentistry and Gerald P. Woodrow, D.D.S., LLC.
Phoenix holds 720 registered dental practices inside the Phoenix-Mesa-Chandler, AZ area, which has 2,741 in total on the Arizona side and ranks 1st in the state. 53 of the Phoenix records also register orthodontics, so this is one of several local options in that category. Across the metro the mix runs general dentistry 63.3%, dental clinic or center 21.3%, orthodontics 6.3%. The closest other registered practices are Dental Design of Arcadia (0 miles, Phoenix), Az Cosmetic & Family Dentistry (0 miles, Phoenix) and Gerald P. Woodrow, D.D.S., LLC (0 miles, Phoenix), with 2 more inside 0.5 miles.
On our figures a routine adult cleaning in Arizona runs $100 to $155 cash and scaling and root planing $175 to $270 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 (480) 748-4264 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 Dunn Orthodontics.
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.
