What the record tells you
Dental Specialty Group, the trading name of Reza Khazaie, DDS, INC, is an NPI registry record for a dental organization at 1255 Willow Pass Rd in Concord, California 94520. CMS issued NPI 1548386279 on 22 March 2007, and the practice last updated its own entry on 29 June 2009. That was 17 years ago, so treat the phone number and the suite number as unconfirmed until someone answers.
It is registered under 4 dental taxonomy codes: Endodontics (1223E0200X), Oral and maxillofacial pathology (1223P0106X), Pediatric dentistry (1223P0221X), Prosthodontics (1223P0700X). That puts it in 4 categories on this site, led by prosthodontics. 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 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 (Contra Costa Dental, NPI 1063538569); it is covered by this page rather than given a page of their own.
Concord holds 58 registered dental practices inside the San Francisco-Oakland-Fremont, CA area, which has 1,785 in total on the California side and ranks 3rd in the state. 1 of the Concord records also register prosthodontics, so this is one of only a handful of local options in that category. Across the metro the mix runs general dentistry 58.1%, dental clinic or center 24.5%, orthodontics 6.8%. The closest other registered practices are Ilas Dental Care (0.4 miles, Concord), Kids Care Dental & Orthodontics - Concord (0.5 miles, Concord) and Surfside Kids Dental (0.6 miles, Pleasant Hill), with 2 more inside 0.6 miles.
On our figures a routine adult cleaning in California runs $130 to $200 cash and scaling and root planing $200 to $330 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 (925) 680-4444 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 Dental Specialty Group.
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.
