How to Verify a Dental License in District of Columbia Before You Hire

One board covers the dental professionals you'll hire: the DC Board of Dentistry, part of DC Health, regulates the practice of dentistry, dental hygiene and dental assistants in the District.

The verification itself runs through DC Health's Health Professional Profile Search, the District's online license lookup.

DC Health says the data behind it is drawn directly from the Health Regulation and Licensing Administration's database, is updated on a daily basis, and is therefore considered a primary source.

One DC rule shapes this whole page: no one may perform duties as a dental assistant in the District without a registration issued by the Board.

This page is the District of Columbia branch of our guide to how to verify a dental license.

Start with the license number: the lookup asks for, at a minimum, the license number or the complete first and last name, and partial information produces inaccurate results.

Pull the number from the candidate's application.

Match the record to your candidate and note the expiration date the record shows.

An expiration that lands on the licensee's birth month is not an error: DC Health moved all professional licenses, certificates and registrations to a birth-month renewal cycle, and credentials issued on or after June 16, 2024 expire on the last day of the holder's birth month.

A clean base license is not the whole check for an associate.

DC regulates dentist and dental-facility certification to administer sedation or general anesthesia under DCMR Title 17, Chapter 107 — a certification separate from the base license.

We could not confirm that this certification appears as a license type in the lookup, so if the role includes sedation, get it from the candidate and confirm it with the Board directly.

Hygienists answer to the same board — the Board of Dentistry regulates dental hygiene too — so run the same lookup the same way: complete name or license number, record matched to the person in front of you, expiration date noted.

The birth-month cycle covers hygiene licenses too, so the same reading rule applies.

What this page won't give you is a list of what a DC hygienist is authorized to do — that is the scope question, not the verification question.

What a DC hygienist must do to become licensed, and which functions need extra authorization, is covered in our guide to dental hygienist requirements in District of Columbia.

For verification the rule is simple: if the schedule assumes a specific expanded duty, confirm the authorization with the Board first.

DC's rule for assistants is blunt: “No person shall perform or be permitted to perform any duties as a dental assistant without a registration issued by the Board” (D.C. Code § 3-1205.1(a)(2); 17 DCMR § 9001.1).

An assistant hire is not verified until you've seen the registration.

DC registers dental assistants at three levels — Level I, Level II and Level III (17 DCMR § 9003) — and the level matters most for radiography.

Under 17 DCMR § 9005.1, only a Level II or Level III dental assistant may place or expose dental x-ray film, and only after passing DANB's RHS or CDA exam or completing a Board-approved radiology course of at least 24 hours.

So verify two things, not one: that the registration exists, and that its level matches the duties you're delegating.

A Level I registration is real — and a real limit on x-ray duties.

How the levels map to the rest of a DC assistant's scope is covered in our guide to dental assistant requirements in District of Columbia.

For discipline, don't stop at the lookup.

The Board publishes a “Dentistry Disciplinary Action Taken” page separately from the license lookup, and we could not confirm what the lookup's own detail view shows for discipline — so treat the separate page as part of the standard check.

Board discipline also travels.

Under the federal NPDB rules, state dental boards must report actions based on professional competence or conduct that revoke, suspend or restrict a dentist's license, censure, reprimand or place a dentist on probation, or accept a license surrender — and a Board of Dentistry counts as a reporting board under those rules.

Because the NPDB sends self-query results only to the practitioner, the candidate has to run one and choose to share it; our guide to NPDB queries covers when a practice can query directly.

A DC check covers DC credentials only.

A candidate who practiced in Maryland or Virginia — or anywhere else — holds licenses other boards issued, so verify each of those with the board that issued it.

A candidate can also arrive carrying obligations from a previous employer, including a restrictive covenant; what DC law allows there is covered in our guide to non-competes in District of Columbia.

Run every check before the offer goes final, and save what you saw: the credential verified, the name and license number matched, the expiration date the record showed, and who ran it and when.

A dated screenshot of the result turns "we checked" into something you can produce later.

Two DC-specific notes for the file.

First, re-verify as each recorded expiration approaches — the birth-month cycle makes the dates predictable once you've seen the first one.

Second, verification has a reporting mirror: DC requires any health professional, and any employer of a health professional, to report certain actions taken by or against the professional to the appropriate board within ten business days.

Which actions trigger the duty is a detail to confirm with the Board before you need it, because the clock is short.

A license check is one layer of screening, not the whole stack.

If your practice bills Medicaid or CHIP, add exclusion screening: people and entities excluded by HHS-OIG can receive no payment from federal health care programs for items or services they furnish, and Medicaid and CHIP count as federal health care programs.

Our guide to OIG exclusion checks covers who to screen and how often.
