What the record tells you
American Dental Group of West Covina, the trading name of Homan Hanasab Dental Corporation, is an NPI registry record for a dental organization at 436 N Sunset Ave in West Covina, California 91790. CMS issued NPI 1770022428 on 14 February 2017, and the practice last updated its own entry on 14 February 2017. That was 9 years ago, so treat the phone number and the suite number as unconfirmed until someone answers.
It is registered under 5 dental taxonomy codes: Dentist (122300000X), Endodontics (1223E0200X), Periodontics (1223P0300X), Oral and maxillofacial surgery (1223S0112X), Orthodontics and dentofacial orthopedics (1223X0400X). That puts it in 5 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. The record also carries 124q00000x, which is a staffing signal rather than a service in its own right. 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. 2 further NPIs are registered to what looks like the same business at this address (American Dental Group of West Covina, NPI 1629304282 and American Dental Group, NPI 1497914154); they are covered by this page rather than given pages of their own.
West Covina holds 99 registered dental practices inside the Los Angeles-Long Beach-Anaheim, CA area, which has 8,403 in total on the California side and ranks 1st in the state. 2 of the West Covina 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 65.8%, dental clinic or center 21.5%, orthodontics 6.5%. The closest other registered practices are Dr A Winter A Profession Corporation (0.5 miles, West Covina), Waheed M Dental of West Covina CORP (0.5 miles, West Covina) and Assure Dental (0.7 miles, West Covina), with 2 more inside 0.7 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 (626) 337-7271 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.

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 American Dental Group of West Covina.
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.
