How To Answer Why Dentistry In Your Interview (With Model Answers) 2026

Why do interviewers ask why dentistry?

Interviewers ask why dentistry because they need to know you understand the job and have tested the idea against something real. A dental degree trains you for one registered profession from the first year, so a reason that doesn't hold up costs you five years.

Your answer also shows how you think, because describing what you saw and how your view shifted is the reflective habit clinical training runs on.

The patients I remember from my first year in practice weren't the complicated ones. They were the people who'd avoided a dentist for a decade and left having booked a check up, because somebody finally explained things without rushing them.

• A dental degree is a five year commitment: the BDS or BChD runs for five years, with patient contact and outreach placements in community clinics.
• They're testing evidence rather than enthusiasm: anyone can say they enjoy science and want to help people, so the useful part is what you did about it.
• They want the hard parts named out loud: repetitive precision work, anxious patients, NHS targets and running a small business are all part of what you're choosing.
• The same question sits in your UCAS form: since 2026 entry the personal statement is three questions, and the first asks why you want to study the course.

The table below is most of what you need: the reasons applicants offer, and what each one needs attached to it.

Key Takeaway: I chose dentistry because I wanted to diagnose the problem and treat it myself, and I checked what that was like before applying.

How do I structure a why dentistry answer?

Structure it as a sequence running from what started your interest to what you now know about the work, so an interviewer can follow how your thinking developed.

1. The spark: what first turned your attention to dentistry, whether that was your own treatment, a relative's job or a careers talk.
2. How you tested it: the placements, virtual work experience and reading you used to check the idea against the real thing.
3. What you learnt that confirmed it: one observation you can describe in detail, and what it told you.
4. What you know it really involves: the precision, the repetition, the anxious patients and the pressures on NHS dentistry.
5. Why dentistry specifically: your reason for choosing it over medicine, and over dental hygiene and therapy.
6. How you've prepared: the reading, the manual work and the dentistry work experience you've lined up.

Ninety seconds to two minutes is usually enough, and you don't need all six every time. In a short station, give the first three and let the interviewer draw out the rest.

Key Takeaway: Start with what drew me in, then spend most of the answer on what I did to check it.

What does a dentist actually do, and why does that matter for my answer?

Most UK dentists work as general dental practitioners on the high street with a mixed NHS and private list, and the rest work in community services, hospital departments, dental public health, the armed forces or academia, as the NHS Health Careers profile of a dentist sets out.

On a Monday morning I might see a child with three decayed baby teeth, a man who wants a broken front tooth rebuilt, and someone in real pain who needs treating there and then. That's the honest version of the variety people mention in interviews.

• NHS and private work sit side by side: most NHS dentists in practice are self employed contractors rather than salaried staff, and many practices run both lists.
• NHS work in England is paid in units of dental activity: a practice delivers a set number of UDAs a year, as our guide to NHS dental bands and UDAs explains.
• Access is the issue shaping the job now: many practices aren't taking on new NHS adult patients, which our NHS dentistry hot topics guide covers alongside the rise in treatment bought abroad.
• There are thirteen recognised dental specialties: orthodontics, oral surgery, paediatric dentistry and restorative dentistry among them, and our career in dentistry guide covers the training.
• Registration is a lifelong obligation: you register with the General Dental Council, work to its Standards for the Dental Team, and complete 100 hours of verifiable CPD every five year cycle.

Manual dexterity here means working in a space the size of a matchbox, upside down through a mirror, on a patient who can't tell you what they feel. The part nobody described to me at seventeen was the business underneath it: rotas, stock and CQC paperwork.

Key Takeaway: I know I am choosing general practice with a mixed NHS and private list, precision work all day, and a business to help run.

How do I answer why dentistry and not medicine?

Answer it honestly and without defending yourself, because the question asks what you understand about both careers rather than testing your loyalty. Name two or three real differences and say which mattered to you.

• The scope is defined: dentistry covers the mouth, teeth and jaws in depth, and some people prefer knowing one area thoroughly.
• You keep the same patients: a dentist may see the same family every six months for twenty years, a continuity hospital medicine rarely offers.
• Problems often resolve within the appointment: you diagnose, treat and see the result the same day, which suits some people more than long term management.
• The craft changes the outcome: your hands affect the result, and the GDC standards hold you responsible for the work you do.
• Independence arrives earlier: dental foundation training is usually one year, whereas medical training runs through rotations and specialty programmes with heavy on call.

If you applied to medicine first, say so plainly and explain what changed your mind. Our reapplying for dentistry guide covers that conversation, and our graduate entry dentistry guide covers the route from another degree.

Why not dental hygiene and therapy?

Dental therapists and hygienists do real clinical work, so treat the question with respect. A dental therapist qualifies through a three year degree and can place fillings, take radiographs, scale and polish and extract baby teeth.

The difference is the breadth of diagnosis and responsibility for the whole treatment plan. Dentists assess the patient overall, plan complex care, carry out surgical extractions and root canal work, and stay accountable.

Key Takeaway: I wanted a defined area I could know thoroughly, work I complete with my own hands, and patients I keep for decades.

Why dentistry model answers

The three answers below use the same structure with completely different evidence, so read them for shape rather than for phrases to borrow.

Model answer: the science led applicant

"I came to dentistry through biology, after an EPQ on how the bacteria in dental plaque cause decay. What pulled me in was that a disease I can describe at a cellular level gets treated by one person in one appointment.

I spent a week in a general practice, where I watched the same dentist explain a root canal three different ways depending on who was in the chair. I had assumed the science would be the difficult part, and it was the explaining.

Since then I have practised fine control by modelling teeth in wax. The work is repetitive and demanding, and I want it because it uses the biology I enjoy on someone who walks out better than they walked in."

Why this answer works:

• The science interest is attached to a specific piece of work, so it holds up.
• Noticing one explanation given three ways is something you only learn by watching carefully.
• It names the repetition and the physical demands without treating them as reasons to hesitate.

Model answer: the applicant who was a nervous patient

"I was frightened of the dentist until I was about thirteen, when I needed two fillings and the dentist talked me through everything before she touched me. That was when I understood that how a clinician behaves changes what a patient can tolerate.

Because I did not want to apply on one good memory, I arranged three days of work experience and a virtual placement. I saw an anxious man who had not been seen for eleven years, and the dentist spent most of that appointment explaining rather than treating.

I have since worked as a lifeguard, which taught me to keep my voice steady when others cannot. Dentistry is precision work on frightened patients, and that is the part I want to be good at."

Why this answer works:

• The personal story is the spark and is then deliberately tested, so it never carries the answer.
• The eleven year gap and the split of time in the appointment are details from real observation.
• The lifeguarding is offered as transferable evidence with a named skill.

Model answer: the first generation applicant

"Nobody in my family works in healthcare, so I started with what I could reach. On a supermarket customer service desk I found I was good at the part where somebody arrives annoyed and leaves feeling dealt with properly.

I emailed about twenty practices before one agreed to two days of shadowing, alongside three virtual work experience programmes. I watched a dentist tell a patient that the tooth he wanted saving could not be saved, then explain the options and let him decide.

Reading about NHS access has filled in the rest. I want a career where I diagnose a problem and treat it myself, in a community I know, and where being decent with people is part of the clinical skill."

Why this answer works:

• The part time job is treated as genuine evidence of patient facing skill.
• Persistence is shown through what the applicant did rather than claimed.
• The tooth that could not be saved shows an understanding of consent without using the word.

Key Takeaway: My reasons only mean something if I can name the moment I saw them being true.

Which follow-up questions come after why dentistry?

The follow ups come straight out of what you've just said, so anything you claim should be something you can discuss for another minute.

• What would you do if you don't get in this year? Give a real plan with a date on it, such as reapplying after a year in a practice or coming through graduate entry.
• What worries you about a career in dentistry? Name something genuine, such as the strain on your back and hands over thirty years, then say what you've seen dentists do.
• What did you see on work experience that put you off? Answer it properly rather than saying nothing did, describe the moment, and finish with what you concluded.
• How do you know you have the dexterity for this? Point to something you practise that needs fine control, and say dental school teaches hand skills on phantom heads first.

Key Takeaway: Everything in my first answer is something I am willing to be asked a harder question about.

How can I talk about my motivation in my dentistry interview?

Talk about your motivation by working backwards from what you've actually done, because your own life holds better evidence than anything you'd invent. A part time job, volunteering, an EPQ or your own treatment all give you something specific.

1. List what you actually did: every placement, virtual programme, job, volunteering role and piece of reading, on one page.
2. Write one sentence of learning beside each: something you now understand that you didn't before, phrased as an observation.
3. Attach each sentence to a reason: match your learning to the reasons in the table above, and drop any reason you can't support.

Interviewers are listening for a consistent set of things:

• Whether your reasons are specific to dentistry rather than healthcare in general.
• Whether you tested the idea somewhere real and changed your mind about anything.
• Whether you can describe the demanding parts of the work without flinching.
• Whether the person speaking matches the person described in the application form.

To rehearse out loud and get marked feedback, our 1-1 dentistry interview tutoring pairs you with a dentistry interview expert matched to the universities you've applied to.

Key Takeaway: My motivation is easiest to explain when I describe what I did and what it taught me, in that order.

Example dentistry interview questions on why dentistry

You are unlikely to be asked any of these word for word, and you do not need a prepared answer to each one. Use them to check your understanding: if you could speak for a minute on most of them, you know this topic well enough for whatever the interviewer actually asks.

Questions to get you thinking

1. Why do you want to be a dentist, and when did you first start thinking about it?
2. Why dentistry rather than medicine?
3. What did you see on work experience that confirmed your choice?
4. What does a general dental practitioner do on a normal working day?
5. Which parts of dentistry would you find hardest, and why?
6. Why not dental hygiene and therapy, or another role in the dental team?

Harder questions to stretch you

1. If dentistry paid the same as any graduate job, would you still apply?
2. What has changed about your reasons for choosing dentistry in the last two years?
3. You have described dentistry as varied, so give me an example of a week that would not be.
4. What would make you leave dentistry ten years after qualifying?

Model answer

"Why do you want to be a dentist?"

"Two things brought me here, and the second is the reason I applied. The first was my own treatment: I had a molar filled at fourteen, and the dentist showed me the decay on the X-ray and explained what she was about to do, which turned something I dreaded into something I understood.

That was interest rather than a decision, so I went to find out what the work was like. I did a week in a general practice and three virtual work experience programmes, and I read around NHS access and the dental contract.

The week in practice decided it, because I watched the same dentist take a child through a first check up, rebuild a chipped front tooth, and tell an anxious man that his tooth needed taking out. What struck me was how much of the skill sat in the explaining.

I know the honest version of this career: it is repetitive, it is hard on your back, and running a practice is a business as well as a clinic. I want it because I would diagnose a problem and fix it myself, for people I would keep seeing for years."

Why this answer works:

• It separates the spark from the decision, so a childhood story never carries the answer.
• The details are observed rather than generic: the three treatments, the X-ray, the explaining.
• It names the difficult parts of the career plainly without turning any of them into a complaint.

Key Takeaway: Say what started it, say what you did to check it, then say what you now know the job really is.

What should I take into the room?

Take one honest reason and one real moment that proves it, because that pairing survives any follow up an interviewer builds on top of it. If you can describe what you saw and what it changed, you'll never need a script.

Next, work through our dentistry interview questions bank, then the ultimate dentistry personal statement guide, our dentistry personal statement examples, how to become a dentist and the best books for a dentistry application.

Motivation is usually one station of several, so once this answer feels like yours, move on to our dentistry ethical scenarios guide, which uses the same plain approach for the ethics stations.

Key Takeaway: One reason I mean, one moment that proves it, and the honesty to say what the job is actually like.
