Dental Hygienist Interview Questions
What to ask, and what a strong answer actually sounds like.
A hygienist interview is short and the clinical questions mostly sort themselves out.
What separates candidates is judgement under a schedule that has slipped, and how they handle the patient who has not been seen in three years.
Ask about those.
Before the interview
Before the interview, verify the licence with your state board by name and number, and confirm any separate permit the role needs.
Doing it first means the interview is about fit rather than paperwork.
Decide in advance what your state actually permits — requirements by state — so you do not ask about duties that are not on the table where you practise.
Clinical judgement
Walk me through how you'd handle a patient who hasn't been seen in three years and has visible calculus and bleeding on probing.
What to listen for: A sequence, not a procedure list: full charting first, then a staged plan, and an explicit point where they'd bring the dentist in.
Candidates who jump straight to scaling without assessment or a perio diagnosis are describing a cleaning, not care.
How do you decide between a prophy and scaling and root planing?
What to listen for: Reference to pocket depths, bone loss, bleeding and clinical attachment — not to what the schedule says or what the patient's insurance covers.
The strongest answers mention documenting the reasoning.
A patient refuses radiographs. What do you do?
What to listen for: Explains why they're needed, documents the refusal, and escalates to the dentist rather than either proceeding blind or arguing.
Look for the documentation instinct.
Schedule and pressure
You're 20 minutes behind and the next patient needs more than the slot allows. What happens?
What to listen for: A real answer names a trade-off — what gets deferred, who gets told, how it's documented.
Anyone who says they simply work faster has either not been in that position or is telling you what they think you want.
How many patients a day have you typically seen, and on what recall interval?
What to listen for: Concrete numbers, and whether they match your practice's load.
A hygienist used to eight patients a day will feel very differently about twelve, and it is better to find that out now.
Scope and licensure
Which permits do you currently hold beyond your RDH licence?
What to listen for: Specifics — local anaesthesia, nitrous monitoring, expanded functions — and which state issued them.
Permits are state-specific, so a permit from a previous state may not transfer.
Has your scope of practice differed between states you've worked in?
What to listen for: Awareness that it varies at all.
A hygienist who has worked in two states and noticed the difference will be careful about the boundary; one who assumes it is the same everywhere may not be.
Worth a second look
None of these is disqualifying on its own.
Each is worth a follow-up question.
- Cannot describe how they'd document a refusal or an unusual finding.
- Talks about production targets before patient assessment.
- Vague about which state issued their licence or when it expires.
- No questions about your schedule, recall interval, or patient load.
- Describes scaling and root planing as a scheduling decision rather than a clinical one.
After the interview
Verify the licence and any additional credentials with the state board before extending an offer, not after.
Licensing is state by state, so it takes minutes online with your own board.
If you are hiring across a state line, confirm what the remote state actually requires before setting a start date.
The Dentist and Dental Hygienist (DDH) Compact has reached activation, but compact privileges are not yet being issued — the commission says implementation takes 18 to 24 months — so for now, ask the remote state's board what its licence-transfer path involves.
Once privileges are issued, a hygienist practising on one will work within the remote state's scope of practice and still need any extra permits that state requires.
