What the record tells you
Dream Dental, the trading name of Timothy Y Kim DMD A Professional Corporation, is an NPI registry record for a dental organization at 5117 Lone Tree Way in Antioch, California 94531. CMS issued NPI 1831068261 on 3 November 2025, and the practice last updated its own entry on 6 May 2026. That is recent, so the contact details are likely to be current.
It is registered under 2 dental taxonomy codes: General practice dentistry (1223G0001X), 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. The same registered name appears at 8 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 other dental record shares the street address: Orthoworks.
Antioch holds 47 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. 8 of the Antioch 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 Orthoworks (0 miles, Antioch), East Bay Dental (0.1 miles, Antioch) and Antioch Dental Specialty (0.1 miles, Antioch), with 2 more inside 1.2 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 (310) 365-8643 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 Dream Dental.
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.
