What the record tells you
Silicon Valley Pediatric Dentistry and Orthodontics-Sunnyvale, the trading name of Ngai and Chang Dental Group, is an NPI registry record for a dental organization at 516 W. Remington Dr. Ste 2 in Sunnyvale, California 94087. CMS issued NPI 1134662828 on 29 November 2016, and the practice last updated its own entry on 4 February 2026. That is recent, so the contact details are likely to be current.
It is registered under 2 dental taxonomy codes: Dentist (122300000X), Pediatric dentistry (1223P0221X). That puts it in 2 categories on this site, led by pediatric 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. 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. 6 other dental records share the street address: William P Melarkey Dental Corporation, Rik A Vanooteghem DDS, MS and Dao Hoang D.M.D. Dental Corporation.
Sunnyvale holds 89 registered dental practices inside the San Jose-Sunnyvale-Santa Clara, CA area, which has 927 in total on the California side and ranks 6th in the state. 5 of the Sunnyvale records also register pediatric dentistry, so this is one of several local options in that category. Across the metro the mix runs general dentistry 64.1%, dental clinic or center 23.6%, oral and maxillofacial surgery 5.8%. The closest other registered practices are William P Melarkey Dental Corporation (0 miles, Sunnyvale), Rik A Vanooteghem DDS, MS (0 miles, Sunnyvale) and Dao Hoang D.M.D. Dental Corporation (0 miles, Sunnyvale), with 2 more inside 0 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 (408) 736-3311 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 Silicon Valley Pediatric Dentistry and Orthodontics-Sunnyvale.
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.
