What the record tells you
Maria T Alarcon DDS Dental Corporation is an NPI registry record for a dental organization at 315 40TH St in Richmond, California 94805. CMS issued NPI 1679103899 on 16 January 2020, and the practice last updated its own entry on 14 April 2021. That was 5 years ago, so treat the phone number and the suite number as unconfirmed until someone answers. CMS records it as a subpart of Maria T Rodriguez DDS, so billing and pricing may follow the parent's policies.
It is registered under 2 dental taxonomy codes: Dentist (122300000X), Dental clinic or center (261QD0000X). That puts it in 2 categories on this site, led by dental clinic or center. 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.
Richmond holds 12 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. 7 of the Richmond records also register dental clinic or center, so this is one of several 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 Vargas Group INC. DBA Guadalupe Dental Clinic (0 miles, Richmond), Edgardo S Rubio DMD CORP (0.1 miles, Richmond) and S Andres Abusleme DDS INC (0.7 miles, Richmond), with 2 more inside 0.8 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 (510) 232-4003 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 Maria T Alarcon DDS Dental Corporation.
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.
