How to Screen Dental Assistants: 9 Questions and What to Listen For Screening Interview Template

Tell me about your dental assisting experience. What kinds of practices have you worked in (general or family, pediatric, oral surgery, endodontic, orthodontic, group practice or DSO), how many operatories were running on a typical day, and how was your time split between chairside assisting and front-office work?

What this assesses: This question sorts the three jobs that share this title before you spend time on anyone. Strong answers name the practice type, give a real number of operatories or providers they supported, and describe the split honestly, something like four ops running with two doctors, ninety percent chairside, covering the front desk at lunch. Be cautious with a candidate whose experience turns out to be mostly scheduling and insurance with occasional chairside coverage, or who cannot say how many chairs were running, which usually means they floated rather than owned a doctor's schedule. A candidate coming from a single-doctor office with two operatories can absolutely work out in a six-chair practice, but you should know you are asking them to change pace, not just employers.

What dental assisting credentials do you hold, and in which state? Are you registered or licensed by the state dental board, do you hold the DANB Certified Dental Assistant credential or a state equivalent, and is your CPR or BLS certification current?

What this assesses: Credential rules for this role are state law, not preference, and they vary more than almost any other clinical support job. Strong answers name the state, name the specific credential and its status, and know their expiration dates and continuing-education requirements. They also flag it directly if they are moving from another state and would need to credential in yours. Be cautious with a candidate who says they are certified without naming the certifying body, assumes a credential transfers between states automatically, or has an expired CPR card they have not renewed. None of that is automatically disqualifying for an on-the-job-trained assistant in a state that allows one, but you need to know exactly what you are hiring so you are not discovering a scope problem in week two.

Are you certified to take dental radiographs in this state, and which images do you take routinely: bitewings, periapicals, a full-mouth series, panoramic, or 3D and cone beam? Roughly what share of your x-rays need a retake, and what usually causes one?

What this assesses: Radiography certification is the single biggest throughput variable in this hire, because an assistant who cannot legally expose films means the doctor or hygienist stops to take them. Strong answers confirm the state radiography credential specifically, list the image types they take without help, and answer the retake question with a real, modest number and a specific cause, usually sensor placement on a patient with a shallow palate or a strong gag reflex, plus what they do about it. Be cautious with a candidate who claims they never retake anything, which is not true of anyone taking films all day, or who cannot distinguish between holding a radiography certification and having watched someone else take x-rays. Cone beam and pano experience is a bonus, not a requirement, unless your office runs implants or surgery.

Which procedures have you assisted on chairside, and where are you strongest: composites and restorative, crown and bridge, endodontics, extractions and oral surgery, implants, pediatric, or ortho? Walk me through how you set up for the one you know best, from tray setup through the doctor's first cut.

What this assesses: The setup walkthrough is the part that cannot be faked. Strong answers move through it in order and in the right vocabulary: the tray they pull, anesthetic and topical staged, isolation and suction placement, matrix and wedge ready before the doctor needs it, curing light within reach, and what they anticipate next rather than what they hand over when asked. Someone who has genuinely done four-handed dentistry talks about staying ahead of the doctor. Be cautious with a candidate who describes only handing instruments when asked, cannot name the tray setup for a procedure they claim to know, or lists every specialty at the same level of comfort. Range is less important than depth in the procedures your practice actually does most.

Which expanded functions are you permitted to perform in this state and which have you actually done: coronal polishing, sealants, fluoride, taking impressions or intraoral scans, fabricating and cementing temporary crowns, placing or removing sutures, or placing restorations as an expanded functions assistant?

What this assesses: Expanded functions decide how much of the appointment the assistant can carry, and they are a separate permission from basic registration in nearly every state. Strong answers separate what they are legally permitted to do from what they have real repetitions in, since those are different things, and give a sense of volume, for example that they take digital scans daily but have only fabricated temporaries a handful of times. Be cautious with a candidate who claims expanded functions without the credential the state requires, or who cannot tell the difference between assisting with a procedure and performing it. An assistant who is honest about a gap here is more useful than one who overstates and then has to be walked back in front of a patient.

Walk me through instrument processing at your last office. What happened to a used instrument from the moment the patient got up until it was back on a tray, and how did you verify the autoclave was actually working?

What this assesses: This is the infection-control question, and the answer to the second half tells you whether the candidate follows a protocol or just runs a machine. Strong answers trace the full path in order: transport in a closed container, ultrasonic or instrument washer, inspection and drying, pouching with an indicator, autoclave cycle, and storage with a date. Then, unprompted, they mention biological or spore testing on a regular schedule and logging results, plus what they do when a cycle fails. Weak answers stop at we ran them through the autoclave. Be cautious with a candidate who has never heard of spore testing, cannot say who was responsible for it, or describes cutting corners on turnover when the schedule got tight, since that is the exact pressure your office will put on them.

Which practice-management and imaging software have you used (Dentrix, Eaglesoft, Open Dental, Curve, Denticon, Carestream, or others)? How comfortable are you charting existing conditions and treatment, entering clinical notes during a full schedule, and keeping the day current without falling behind?

What this assesses: Software familiarity is worth about a week of ramp time, which matters more than most offices admit when a chair is sitting empty. Strong answers name the systems, say what they did in them rather than just listing logos, and are specific about charting existing restorations and perio findings, entering notes, and where they slow down. Be cautious with a candidate who lists five systems with no detail, or who says they always left notes for the end of the day, since notes written at six in the evening from memory are how documentation problems start. A candidate who has only used one system but knows it deeply usually picks up a second faster than someone who has skimmed four.

Tell me about a patient who was clearly anxious or in pain in your chair. What did you notice, what did you do, and what did you say to the doctor?

What this assesses: Assistants spend more time with the patient than the doctor does, and they are the ones who catch the signals. Strong answers describe something concrete they observed, white knuckles, a raised hand, holding their breath, a child who stopped answering, followed by a specific action: stopping to explain the next step, adjusting the chair or the suction, giving the patient a signal to raise a hand, and telling the doctor what they saw rather than waiting to be asked. Be cautious with a candidate who only says they stayed calm and reassured the patient, which is a phrase everyone reaches for, or who describes pushing through because the schedule was tight. In pediatric and oral surgery practices, weight this question heavily, since it predicts more of the job than instrument knowledge does.

What schedule are you looking for, including whether you can work early mornings, evening hours, or Fridays and Saturdays if we run them? Are you open to covering at another one of our locations, and what pay range are you targeting?

What this assesses: Schedule and pay are the two reasons this hire falls apart in the first month, and leaving them to the offer stage wastes everyone's time. Strong answers commit to specific days and hours, are direct about hard constraints such as childcare or school, say plainly whether traveling between offices works for them, and name a pay number that lines up with the credentials and experience they described. Be cautious with a candidate who wants a four-day schedule at a practice that runs five, is vague about float coverage you know the role requires, or names a number well above your range for the scope they can actually perform. Ask every applicant these same nine questions and score them on the same [structured interview](/glossary/structured-interview) rather than on the ones who happened to interview well, which is what keeps [high-volume recruiting](/glossary/high-volume-recruiting) consistent when you are staffing chairs across several offices at once.
