What the record tells you
Colorado Dental Specialists, the trading name of Colorado Dental Specialist Practice, LLC, is an NPI registry record for a dental organization at 3955 E 120TH Ave Ste B in Thornton, Colorado 80233. CMS issued NPI 1841844479 on 31 July 2019, and the practice last updated its own entry on 31 July 2019. That was 7 years ago, so treat the phone number and the suite number as unconfirmed until someone answers. CMS records it as a subpart of Colorado Dental Specialist Practice, LLC, so billing and pricing may follow the parent's policies.
It is registered under 4 dental taxonomy codes: Endodontics (1223E0200X), Periodontics (1223P0300X), Oral and maxillofacial surgery (1223S0112X), Orthodontics and dentofacial orthopedics (1223X0400X). That puts it in 4 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 same registered name appears at 15 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. 2 further NPIs are registered to what looks like the same business at this address (Apple Tree Dental, NPI 1710531488 and My Dentist INC., NPI 1861663668); they are covered by this page rather than given pages of their own.
Thornton holds 69 registered dental practices inside the Denver-Aurora-Centennial, CO area, which has 1,791 in total on the Colorado side and ranks 1st in the state. 3 of the Thornton 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 56.8%, dental clinic or center 19.9%, orthodontics 12.2%. The closest other registered practices are Bella Sonrisa, LLC (0.6 miles, Thornton), Kids & Family Dentistry & Orthodontics (0.9 miles, Thornton) and Thornton Family Dentistry & Orthodontics (0.9 miles, Thornton), with 2 more inside 1 miles.
On our figures a routine adult cleaning in Colorado runs $110 to $165 cash and scaling and root planing $180 to $280 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 (303) 255-4855 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 Colorado Dental 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. Treat them as a starting point and call two or three offices for an actual quote.
