How to Verify a Dental License in New Hampshire Before You Hire
Run the state's Online License Verification for every dentist and hygienist hire — and check sedation, anesthesia and assistant credentials separately.
In New Hampshire, you verify a dentist or dental hygienist on the state's Online License Verification site — the New Hampshire Board of Dental Examiners points employers there for current status and disciplinary documents.
Dental assistants are the exception: the state does not license ordinary assistants, so their x-ray and expanded-duty qualifications live on course certificates the assistant keeps.
Here is what to run, which permits to check separately, and what to file.
Rules vary by state and change
This guide explains federal rules and the state rules it names, as of the date above.
Employment law and dental-practice rules differ by state and are revised often, so confirm current requirements with your state dental board, labor agency or employment counsel before you act on them.
It is general information, not legal advice.
Who licenses dental professionals in New Hampshire
The New Hampshire Board of Dental Examiners governs and regulates the practice of dentistry and dental hygiene in the state, examining, licensing and registering the applicants it finds qualified.
It is administered by the Office of Professional Licensure and Certification (OPLC) in Concord, and its "Who We Regulate" list runs exactly two entries deep: dentists and dental hygienists.
New Hampshire does not license or register ordinary dental assistants — the one exception is the Expanded Function Dental Auxiliary (EFDA), who registers with the board and holds a permit.
So:
- Dentists and hygienists — run the state's online license lookup.
- EFDAs — verify the EFDA permit itself; an EFDA who is a licensed hygienist also runs the lookup above.
- Other assistants — no license to look up; verify the board-specified course certificates they hold (below).
This is the New Hampshire chapter — the national process is in our guide to how to verify a dental license.
Looking up a dentist's license
The board's "License Lookup" link takes you to New Hampshire's Online License Verification site at forms.nh.gov/licenseverification — run the dentist through it yourself and save what you find.
The board says the site provides the disciplinary documents and the current status of the license.
Read the status against OPLC's published definitions:
| Status | What OPLC says it means |
|---|---|
| Active | Current and valid — full scope of practice, no restrictions |
| Active-Restricted | Active, but restricted by order of OPLC or the board |
| Suspended | Still valid and renewable, but the ability to practice is temporarily barred by order of OPLC and/or the regulatory body |
| Expired | Up to one year past the expiration date |
| Lapsed | More than one year past expiration — cannot be reinstated |
One caveat: the exact fields the site displays could not be confirmed when we researched this page — it blocks automated access.
Treat the board's description as the guide, collect anything a search does not surface as a document, and confirm it with the board.
Sedation is the example that matters most.
OPLC issues New Hampshire dentists separate sedation permits in four types: general anesthesia/deep sedation/moderate sedation (all ages), moderate sedation only (patients 13 and older), moderate sedation with a pediatric qualification, and pediatric minimal sedation (patients under 13).
If the associate will sedate, ask for the matching permit.
How a dentist earns a New Hampshire license is a different question — our guide to dentist licensure requirements in New Hampshire covers it.
Hygienist licenses and permits
Hygienists verify in the same place: the board licenses dental hygiene alongside dentistry, so the same site and the same status definitions apply.
One permit to ask about is local anesthesia.
A New Hampshire hygienist qualified to administer local anesthesia must obtain a local anesthesia permit from the board — so if the role includes chairside anesthesia, the license alone does not answer it.
Whether the lookup displays that permit is something we could not confirm; ask the hygienist for the permit itself and keep a copy.
What New Hampshire requires to become a hygienist is on our dental hygienist requirements in New Hampshire page.
Dental assistant registrations, certificates and permits
Start with what New Hampshire does not do: ordinary dental assistants are not licensed or registered, so there is no board record to pull for a chairside hire — qualification lives on paper the assistant keeps.
Under the board's rules (Den 302.06), an assistant aged 18 or older is "qualified" in an expanded duty area by completing the required course or exam — and the assistant, not the board, keeps the course certificate, which must be provided to the board on request.
Ask for the certificates before the first day and keep copies in your file.
Radiology is the credential to check first.
A New Hampshire assistant is qualified in dental radiology after an expanded duty radiology course of at least 8 lecture and 8 lab hours that includes passing DANB's radiology exam — unless they have been practicing since before December 9, 1998, which exempts them from the DANB exam.
Radiology by assistants is allowed only under the direct supervision of a licensed dentist.
DANB's Verify Credentials tool can corroborate the DANB exam; the New Hampshire qualification itself is the course certificate.
The exception is the Expanded Function Dental Auxiliary: a hygienist, or a certified or graduate dental assistant, who has completed an EFDA restorations course.
An EFDA must register with the board and hold an EFDA permit — renewed in odd-numbered years before May 1 and displayed where they work.
Look for the displayed permit, and note New Hampshire allows a maximum of 2 EFDAs employed in a dental practice regardless of the number of dentists.
What each credential allows an assistant to do is on our dental assistant requirements in New Hampshire page.
Discipline history and other states
For discipline, the board points you back to the Online License Verification site — the tool it names for determining a licensee's discipline history.
One limit on the board's own Board Actions web page: the board retains disciplinary documents there for a 7-year period, so don't rely on that page for older discipline.
If a reference hints at older history, ask directly and confirm with the board.
Board discipline also has a federal shadow.
When a state dental board acts on a dentist's professional competence or conduct — revoking, suspending or restricting a license, censuring, reprimanding, placing the dentist on probation, or accepting a license surrender — it must report the action to the National Practitioner Data Bank (45 CFR 60.8), whose regulations count a state Board of Dentistry among its reporters (45 CFR 60.3).
A practice that cannot query the data bank directly still has a route: any practitioner can run a self-query, the NPDB sends the response only to the practitioner, and they may share it with whomever they choose — ask your dentist finalist for one.
Our guide to NPDB queries covers eligibility and the self-query in depth.
And for a candidate who has practiced elsewhere: licenses are issued and verified state by state — our research found no national dental license lookup — so run the other state's board lookup the same way.
Documenting the check
A verification is only worth what you can prove.
For each credential, save the date you ran the search and a screenshot or PDF of what the record showed — plus the copies you collected: assistant course certificates, the EFDA permit, and any local anesthesia or sedation permit the role requires.
Run the check close to the start date, and again before you renew an employment agreement — last year's printout says nothing about today's status.
When you need an official verification rather than your own screenshot — for a hospital credentialing file, another state's board or an insurer — OPLC handles official license verifications for the Board of Dental Examiners through VeriDoc, transmitted electronically to the requesting state or organization.
Fold the license file into the rest of the screen: references, your other background checks, and the federal exclusion list where it applies — our guide to OIG exclusion checks covers when and how.
Contract terms get set at the same stage: before drafting an offer for an associate from another New Hampshire practice, see our guide to non-competes in New Hampshire.
Before the first patient: the New Hampshire check
- Run the state's Online License Verification search for each dentist and hygienist finalist, and save what it shows with the date you ran it.
- Read the status against OPLC's definitions — Active-Restricted means get the underlying order and check the restrictions against the role; Suspended means the licensee is temporarily barred from practicing, so no clinical work.
- For a dentist who will sedate, ask for the permit that matches the sedation offered — general anesthesia/deep sedation/moderate sedation, moderate sedation only (13+), moderate sedation with pediatric qualification, or pediatric minimal sedation (under 13).
- For a hygienist who will administer local anesthesia, ask for the local anesthesia permit itself.
- For every assistant, collect the course certificates for radiology and any expanded duty they will perform — radiology requires the course with DANB's exam unless they have practiced since before December 9, 1998.
- For an EFDA, check the board permit displayed where they work, and confirm the hire keeps the practice within the 2-EFDA cap.
- For a candidate licensed in another state, run that state's board lookup too.
- Ask each dentist finalist for an NPDB self-query result.
Questions employers ask
Does New Hampshire license dental assistants?
No. The Board of Dental Examiners' "Who We Regulate" list covers dentists and dental hygienists only.
Assistants qualify for expanded duties such as radiology by completing board-specified courses and keep their own completion certificates.
The exception is the Expanded Function Dental Auxiliary, who must register with the board and hold an EFDA permit displayed where they work.
What does the New Hampshire dental license lookup show?
The board says New Hampshire's Online License Verification site provides the current status of the license and the licensee's disciplinary documents.
OPLC publishes status definitions — among them Active, Active-Restricted, Suspended, Expired and Lapsed — so read a result against those definitions.
The exact fields displayed for each record could not be confirmed by our research, so collect anything a search does not surface as a document.
How do I get an official verification of a New Hampshire dental license?
Official license verifications for the Board of Dental Examiners are handled through VeriDoc and are transmitted electronically to the requesting state or organization.
A dated screenshot of the online lookup is fine for your own hiring file, but for another state's board, a hospital or an insurer, use the official route.
How do I verify a New Hampshire dental assistant's x-ray qualification?
Ask for the course certificate.
An assistant is qualified in dental radiology after an expanded duty radiology course of at least 8 lecture and 8 lab hours that includes passing DANB's radiology exam — unless they have been practicing since before December 9, 1998, which exempts them from that exam.
DANB's Verify Credentials tool can corroborate its own certifications, but the New Hampshire qualification is the course certificate itself.
Can a New Hampshire hygienist administer local anesthesia?
Only with the permit: a New Hampshire hygienist qualified to administer local anesthesia must obtain a local anesthesia permit from the board.
If you are hiring for a hygiene role that includes chairside anesthesia, check the license itself on the state's online verification site and ask the hygienist for a copy of the permit.
Is there a national dental license lookup?
Not one we could source.
Licenses are issued and verified state by state, so a New Hampshire hire is checked on New Hampshire's Online License Verification site, and any out-of-state license on that state's own board lookup.
The National Practitioner Data Bank is not a license lookup — it is a reporting data bank that state dental boards report certain discipline to.
