What the record tells you
Oak Mill Dental Group CORP is an NPI registry record for a dental organization at 7900 N Milwaukee Ave, Suite 2-24 in Niles, Illinois 60714. CMS issued NPI 1285070615 on 13 May 2013, and the practice last updated its own entry on 28 February 2014. That was 12 years ago, so treat the phone number and the suite number as unconfirmed until someone answers.
It is registered under 4 dental taxonomy codes: Dentist (122300000X), Endodontics (1223E0200X), General practice dentistry (1223G0001X), Oral and maxillofacial surgery (1223S0112X). That puts it in 3 categories on this site, led by general 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. One further NPI is registered to what looks like the same business at this address (Oak Mill Family Dental, NPI 1285016709); it is covered by this page rather than given a page of their own. 2 other dental records share the street address: Krystyna Wagenhejm Ciesielski DDS PC and Optima Dental Care.
Niles holds 39 registered dental practices inside the Chicago-Naperville-Elgin, IL-IN area, which has 4,610 in total on the Illinois side and ranks 1st in the state. 31 of the Niles records also register general dentistry, so this is one of several local options in that category. Across the metro the mix runs general dentistry 69.1%, dental clinic or center 19.2%, orthodontics 6.2%. The closest other registered practices are Krystyna Wagenhejm Ciesielski DDS PC (0 miles, Niles), Optima Dental Care (0 miles, Niles) and Nwdg Niles LLC (0 miles, Niles), with 2 more inside 0.3 miles.
On our figures a routine adult cleaning in Illinois runs $110 to $165 cash and scaling and root planing $180 to $285 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 (847) 470-0240 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 Oak Mill Dental Group CORP.
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.
