Why not dental therapy or hygiene?

This question isn’t about proving that dentistry is “better” than other roles – it’s about showing genuine appreciation for the wider dental team while clearly justifying why you specifically want to become a dentist. A strong answer draws on real understanding from your work experience or research, comparing roles fairly rather than dismissively.

Part 1: Understanding the wider dental team

Every member of the dental team plays a necessary role, and effective patient care depends on collaboration, not any single profession working in isolation. This includes receptionists, nurses, hygienists/therapists, and dentists – each contributing something essential.

The role of a dental nurse

• Working closely alongside the dentist to keep procedures running smoothly
• Decontaminating the surgery between patients
• Providing reassurance and comfort to patients during treatment
• Maintaining patient confidentiality

Nurses are essential to how a practice functions day-to-day, and their contribution should never be underestimated or taken for granted.

The role of a dental hygienist

• Focusing on gum health and prevention
• Carrying out scale and polish, and applying fluoride varnish and fissure sealants
• Giving tailored oral hygiene and diet advice

The role of a dental therapist

• Providing treatment within their defined scope of practice
• Carrying out procedures such as fillings, scale and polish, and extracting baby teeth
• Maintaining patient confidentiality
• Liaising closely with dentists

Dental therapists play a particularly important role in prevention, helping educate patients on how to better care for their own oral health. Their contribution is just as valuable as a dentist’s, simply in a different capacity.

The role of a dentist

• Providing the full range of treatment, including procedures dental therapists cannot perform, such as root canal therapy
• Maintaining patient confidentiality
• Prescribing drugs within their scope of practice
• Managing more complex dental cases

Dentists carry out a broader range of procedures than nurses or therapists, and with that comes a greater level of responsibility.

Part 2: Why dentistry, specifically

Dentists hold the broadest clinical responsibilities within the dental team, requiring more advanced scientific and clinical knowledge. The role also carries significant leadership, decision-making, and treatment-planning responsibility – dentists are typically the ones directing a patient’s overall care, coordinating with the wider team to deliver it.

This is where your answer should become personal: rather than simply stating that you want “more responsibility,” explain why – link your own strengths, skills, and motivations directly to the qualities the role demands. You should also acknowledge that dentistry involves a more hands-on, practically demanding clinical role with a broader range of treatments, and reflect honestly on why that appeals to you specifically.

Suggested structure for this question

• Acknowledge the value of the whole dental team, explaining that effective care depends on collaboration between receptionists, nurses, hygienists, therapists, and dentists.
• Outline the key differences between the roles of nurse, hygienist, therapist, and dentist, showing genuine understanding of each.
• Explain why dentistry specifically appeals to you, focusing on the broader clinical scope, leadership, and decision-making responsibilities involved.
• Link your own personal strengths and motivations directly to the qualities expected of a dentist, rather than listing generic traits.
• Acknowledge honestly that this comes with greater responsibility and workload, showing you’ve thought realistically about what the role demands – not just its appeal.
• Keep your reasoning consistent throughout your answer, so the interviewer comes away with a clear, coherent picture of why dentistry – specifically – is the right path for you.
