License verification guide
How to Check If a Dentist Is Licensed
A complete guide to verifying any U.S. dentist's license through their state dental board — what to check, what red flags mean, and direct links to every state lookup tool.

Why license verification matters
Every dentist practicing in the United States must hold an active license issued by the state dental board where they practice. A license confirms the dentist has completed an accredited dental program, passed required examinations, and meets ongoing continuing-education requirements. License lookups also surface any public disciplinary actions on the dentist's record.
Step-by-step: how to check a dentist's license
- Identify the state where the dentist practices.
- Open that state's dental board license lookup (links below).
- Search by the dentist's last name, license number, or NPI.
- Confirm status (Active, Inactive, Expired, Suspended, Revoked) and review any disciplinary history.
- Cross-check the dentist's name with the federal NPI Registry and the practice website.

What to look for in license lookup results
- Status: Active is required to practice. Inactive, Expired, Suspended, or Revoked are red flags.
- Issue and expiration dates: licenses are renewed on state-specific cycles.
- License type: Dentist (DDS/DMD), dental specialty permit, dental hygienist, dental assistant.
- Disciplinary history: consent orders, probation, restrictions, fines.
- Office address on file: should match the practice you plan to visit.
State license vs federal NPI
The federal NPI Registry (NPPES) is a national directory of every healthcare provider. It confirms identity and specialty, but it does not authorize practice. State licensure is what grants permission to provide dental care in a given state. Verify both.

Before you book: what to check
Use the state board — not Google
The state dental board's license portal is the only authoritative source for active status, expiration, and discipline.
Match the license to the NPI
Names sometimes vary between records. Confirm the license, NPI, and practice address all point to the same person.
Check for discipline history
Most state portals list public actions. A clean record is a green light; anything else deserves a follow-up question.

Frequently asked questions
How do I check if a dentist is licensed?
Identify the state where the dentist practices, open that state's dental board license lookup tool, and search by last name or license number. Review status, issue date, and any disciplinary history.
Is a license the same thing as an NPI number?
No. The federal NPI Registry (NPPES) confirms a provider's national identifier, but state licensure is what authorizes them to practice in a given state. Verify both.
What does it mean if a dentist's license is inactive, expired, or suspended?
Inactive or expired means the dentist is not currently authorized to practice. Suspended or revoked means the state board has taken disciplinary action — the dentist cannot legally provide care under that license.
Can a dentist practice in multiple states?
Yes, but they must hold an active license in each state where they practice. A license in one state does not authorize practice in another.
Are dental hygienists and dental assistants licensed too?
Dental hygienists are licensed in every state. Dental assistants are licensed or registered in most states. Both can be verified through the same state dental board lookup tool.
