How to Verify a Dental License in Missouri Before You Hire

Dentists, dental specialists and dental hygienists in Missouri are licensed under the rules of the Missouri Dental Board (20 CSR 2110), a division of the Missouri Department of Commerce and Insurance.

The board's website is the front door for employers: it links to the Division of Professional Registration's division-wide licensee search.

Assistants sit outside that licensing system.

Missouri's rules define a dental assistant as an employee of a Missouri-licensed dentist other than a hygienist or a certified dental assistant, so there is no assistant license to look up.

What you can verify are board-issued permits and, for certified assistants, DANB certification.

Where that leaves each credential:

Start with how to verify a dental license for the general process, then apply the Missouri specifics below.

Start at the Missouri Dental Board's website, which sends employers and the public to the Division of Professional Registration's licensee search — one search run by the division, not the board itself.

Run it, and match what returns to the license number on the candidate's certificate, not just the name.

One honest limit: that search is a JavaScript portal our research tools could not read, so we cannot tell you which fields a result shows.

Whatever the record displays — a license status, an expiration date, anything about discipline or permits — read it on screen and save a dated screenshot of it.

When you need the board's own formal record, order its written verification of licensure: it includes the licensee's name, license number, license status, original issue date, expiration date, method of licensure and any disciplinary action, and it carries the board seal and an official signature.

Verifications must be requested by mail with a $20.00 fee, as of October 7, 2026.

Sedation is verified separately from the license.

The board issues dentists individual permits and site certificates for deep sedation/general anesthesia and for moderate sedation, and moderate sedation permits cover enteral, parenteral or pediatric moderate sedation — each with its own individual permit and site certificate.

If the associate will sedate patients, ask which permit they hold and see the site certificate — we could not confirm that the division search displays these permits, so confirm them with the board.

Earning the license is a different question — dentist licensure requirements in Missouri covers that side.

Hygienists are licensed under the same board rules as dentists, so their licenses sit in the same division-wide search.

The permits are where a Missouri hygiene hire needs a closer look: a Missouri hygienist needs separate board-issued permits to administer nitrous oxide analgesia and local anesthesia, and may give local anesthesia — infiltration and block — only after receiving a board-issued local anesthesia permit.

If your schedule counts on nitrous or local anesthetic, ask for each permit by name before the offer, not after the first patient.

We could not confirm that the division search displays hygiene permits, so confirm them with the board when the result does not show them.

What the permits take to earn: our guide to dental hygienist requirements in Missouri.

There is no assistant license to look up: Missouri's rules define a dental assistant as an employee of a Missouri-licensed dentist, and a certified dental assistant as one currently certified by the Dental Assisting National Board (DANB).

DANB's own Verify Credentials tool confirms whether a person holds DANB credentials — national certifications such as the CDA, national exam certificates, or a DANB-administered state certificate in Arizona or Oregon.

It confirms the credential, not a Missouri authorization.

The Missouri credential is the expanded functions permit: the board issues permits authorizing a dental assistant, certified dental assistant or Missouri-licensed hygienist to perform expanded functions duties on delegation from a Missouri-licensed dentist, in five categories — restorative I, restorative II, removable prosthodontics, fixed prosthodontics and orthodontics.

Check which category a candidate holds, not just that a permit exists.

Check dates and discipline too: expanded functions permits are subject to discipline by the board under section 332.321, RSMo, and a permit not renewed within one year of its expiration date is void.

A lapsed permit on a résumé may already be dead — read the expiration before you schedule expanded-functions duties.

On x-rays, our read of the board's assistant rules found no radiography credential defined — confirm current credentialing with the Missouri Dental Board if the role includes taking radiographs.

The full scope picture is on our guide to dental assistant requirements in Missouri.

The board publishes a separate online Discipline list naming disciplined licensees, with the date each entry was last modified.

Search the candidate's name there even when the license record looks current; the modified dates tell you how fresh each entry is.

Discipline also surfaces at the National Practitioner Data Bank: state dental boards must report to the NPDB any action based on professional competence or conduct that revokes, suspends or restricts a dentist's license, censures, reprimands or places a dentist on probation, or accepts a license surrender — and boards of dentistry count as NPDB reporters.

Querying is limited to eligible entities, so the practical route is the candidate's self-query, which the practitioner may share with whomever they choose.

Our guide to NPDB queries covers who can query and how.

The Missouri records end at Missouri: if your candidate has practiced in another state, verify that license with the issuing state's own board — our research found no single national dental license lookup.

Run the rest of your screening alongside the license check, OIG exclusion checks included: someone excluded by HHS-OIG can receive no payment from federal health care programs for items or services they furnish, order or prescribe, and those programs include Medicaid and CHIP, so a practice that bills them is covered.

Save what you saw, the day you saw it: a dated screenshot of each search result, the discipline-list result for the candidate's name, and every permit document the candidate gave you.

Note the dates the board itself displays — a discipline entry's last-modified date, a permit's expiration — in the file.

For the formal record, the board's written verification — requested by mail with the $20.00 fee — puts the license status, original issue date, expiration date and any disciplinary action under the board seal and an official signature.

Order it for an associate hire, or anyone whose credential history needs more than your screenshot.

Calendar the re-checks around the expiration dates you recorded, and again before someone takes on a duty that needs its own credential — a sedation permit, a hygiene anesthesia permit, or an expanded functions category the hire did not hold before.
