What the record tells you
The Smile Specialists, the trading name of Mona Derentz D.D.S., INC, is an NPI registry record for a dental organization at 19100 Ventura Blvd Ste 3 in Tarzana, California 91356. CMS issued NPI 1508528142 on 11 October 2021, and the practice last updated its own entry on 11 October 2021. That was 4 years ago; the details are probably current, but confirm the address when you book.
It is registered under 2 dental taxonomy codes: Oral and maxillofacial surgery (1223S0112X), Orthodontics and dentofacial orthopedics (1223X0400X). That puts it in 2 categories on this site, led by orthodontics. 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 2 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: R. A. Macasaet Dental Corporation.
Tarzana holds 54 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. 6 of the Tarzana records also register orthodontics, so this is one of several 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 A Morvarid DDS INC (0 miles, Tarzana), R. A. Macasaet Dental Corporation (0 miles, Tarzana) and Karla Thompson, DDS, INC (0.1 miles, Tarzana), with 2 more inside 0.1 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 (818) 925-2599 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 The Smile Specialists.
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.
