What is confidentiality?

At its core, confidentiality is about protecting a patient’s personal information and only using or sharing it for the purpose it was intended — with disclosure to third parties happening only in specific, justified circumstances. It’s one of the most fundamental principles in healthcare, and interviewers will expect you to understand not just what it means, but why it matters and when it can reasonably be set aside.

Why confidentiality matters

Confidentiality isn’t just a box-ticking exercise — it underpins the entire relationship between a clinician and their patient:

• It builds trust — patients are far more likely to disclose sensitive, relevant information (medical history, lifestyle factors, concerns) if they believe it will be kept private.
• It’s a formal requirement of the GDC, forming part of the professional standards every dentist is expected to uphold.
• It reflects a broader ethical obligation to respect patients as individuals with a right to privacy.
• It protects the reputation of the profession as a whole — a single breach can damage public confidence in dentistry more widely, not just in one practice.

When confidentiality can be breached

Confidentiality isn’t absolute. There are specific, recognised situations where breaching it is appropriate — and it’s important to know these rather than presenting confidentiality as unconditional:

• When the patient has given consent to share their information.
• When disclosure is required by law.
• When there is a clear risk of harm or abuse — for example, safeguarding concerns involving a child or vulnerable adult.

Being able to name these exceptions shows the interviewer you understand confidentiality as a principle with boundaries, not a blanket rule — which reflects real clinical judgement.

Making your answer personal

Where possible, include a short example from your own experience — a time you had to keep something confidential, whether in a work experience setting, a part-time job, or another responsibility. This doesn’t need to be dramatic; it just needs to show the interviewer that you understand what it feels like to be trusted with sensitive information, and that you handled it appropriately. This goes a long way in demonstrating honesty and trustworthiness — qualities that are essential in any healthcare professional.

Suggested structure for this question

• Define confidentiality clearly — the protection of a patient’s personal information, used only for its intended purpose, which can be breached only in specific circumstances.
• Explain why it matters, touching on trust, professional standards, ethics, and public confidence in the profession.
• Name the situations where confidentiality can be breached, giving at least one example for each.
• Share a personal example of a time you had to maintain confidentiality, showing self-awareness and integrity.
