Interview Questions to Ask a Dental Hygienist Candidate
Questions that surface real evidence of clinical precision and patient comfort, backed by a real license — plus what to actually listen for in the answer, not just whether they say the right buzzwords.
1. Describe your approach to a deep cleaning for a patient with early gum disease.
What to listen for: Expect charting pocket depths, careful scaling and root planing, patient comfort, and clear follow-up and home care advice.
2. A nervous patient is gripping the chair and wants to leave. How do you respond?
What to listen for: Good answers slow down, explain each step, agree a stop signal, and respect the patient's choices.
3. How do you ensure instruments and surfaces are properly sterilised between patients?
What to listen for: Look for knowledge of cleaning, sterilisation cycles, indicators, barrier protection, and logging each step.
4. You notice a suspicious lesion on a patient's tongue during a routine visit. What do you do?
What to listen for: Strong answers record details, alert the dentist at once, inform the patient calmly, and follow up.
5. What would you do in your first 30 days in this dental hygienist role?
What to listen for: Whether their plan is grounded in the role's actual must-haves (dental cleanings & scaling and patient assessment) or generic ("get to know the team"). Specificity here signals real understanding of the job, not just interview prep.
6. Why are you leaving your current role, and why this one specifically?
What to listen for: Forward-looking motivation tied to something concrete about this role, versus badmouthing a past employer or vague dissatisfaction. Watch for whether their reasons actually match what this role offers.

Frequently asked questions
How many of these questions should I ask in one interview?
3-4 is realistic for a 30-45 minute interview once you leave room for follow-ups and the candidate's own questions. Divide competencies across panel members rather than every interviewer asking all of them — see the Interview Scorecard tool for a structured version of this.
