What the record tells you
Dentalbug. Com, the trading name of Tsaknis Dental Group, is an NPI registry record for a dental organization at 1221 Massachusetts Ave NW in Washington, District of Columbia 20005. CMS issued NPI 1639476542 on 12 February 2011, and the practice last updated its own entry on 12 February 2011. That was 15 years ago, so treat the phone number and the suite number as unconfirmed until someone answers.
It is registered under 3 dental taxonomy codes: Dentist (122300000X), General practice dentistry (1223G0001X), Periodontics (1223P0300X). That puts it in 2 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. The record also carries 124q00000x, which is a staffing signal rather than a service in its own right. 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 (City Dental Dc Mass., PC, NPI 1013338573); it is covered by this page rather than given a page of their own.
Washington holds 344 registered dental practices inside the Washington-Arlington-Alexandria, DC-VA-MD-WV area, which has 347 in total on the District of Columbia side and ranks 1st in the state. 224 of the Washington records also register general dentistry, so this is one of several local options in that category. Across the metro the mix runs general dentistry 65.1%, dental clinic or center 19%, orthodontics 9.2%. The closest other registered practices are Spa Dental Group INC. (0.2 miles, Washington), Smile Dental Spa (0.2 miles, Washington) and Ivory Dental Centre PC (0.2 miles, Washington), with 2 more inside 0.3 miles.
On our figures a routine adult cleaning in District of Columbia runs $155 to $260 cash and scaling and root planing $230 to $380 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 (202) 628-7979 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 Dentalbug. Com.
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.
