How to Get Your Dental Hygiene License

Passing your boards makes you eligible; a license is what actually lets you work. Licensure is granted by each state, so the exact steps vary — but the shape of the process is consistent everywhere.

The usual building blocks

1. Graduate from a CODA-accredited dental hygiene program.
2. Pass the national written board exam.
3. Pass a clinical exam your state accepts.
4. Often, pass a state or regional jurisprudence exam covering local dental laws and rules.
5. Submit an application to the state dental board with fees, transcripts, exam results, and a background check.

Where states differ

This is the part to research carefully for the state where you plan to work. States vary in which clinical exam they accept, whether they require a jurisprudence exam, what background checks and immunizations they mandate, and which additional functions hygienists may perform — such as administering local anesthesia or nitrous oxide, which not all states permit.

Your state dental board’s website is the authoritative source. Requirements, fees, and accepted exams change — always confirm directly before you apply.

Don’t forget the extras

• Current CPR / basic life support certification is commonly required.
• Some states require additional certifications for expanded functions like local anesthesia.
• If you might move, look into licensure by credentials or endorsement, which can ease transferring an active license to another state.

After you’re licensed

Once your license is active, track its renewal date and continuing-education requirements from the very beginning. It’s far easier to log your CE as you go than to reconstruct it under a renewal deadline.
