Ireland is a popular choice for internationally trained dentists, but the route to full registration is quite specific. For many dentists qualified outside the EU and EEA, it means passing the Dental Council of Ireland’s registration examination, often called the IDC exam.

Compared with some other licensing exams, the IDC exam has fewer places, a tighter structure and limited attempts. That makes careful preparation even more important. This guide covers how the exam works and how to approach it.

The Dental Council updates its requirements and dates each cycle, so always check the official guidance before you apply.

Who Needs to Take It?

The examination is for dentists seeking full registration on the Register of Dentists under the relevant section of the Dentists Act 1985. Before you can sit it, the Council assesses your qualifications and experience. Requirements described by the Council include:

• A dental qualification judged to be an acceptable course, broadly comparable to a five-year full-time programme
• Evidence of three consecutive years of lawful dental practice within the previous five years (recent graduates need continuous practice since graduating)
• A Certificate of Good Standing from your most recent place of practice
• English language evidence, such as OET (Dentistry) with at least a B in each module, or Academic IELTS with at least 7.0 in each module, usually taken within two years before applying

Places are limited and have been allocated by random selection, so not every eligible applicant gets a seat in a given year. You can read more on our IDC exam guide.

How the Exam Is Structured

The IDC exam has two parts, usually held a couple of months apart.

Part 1

Part 1 has typically been held in Dublin and includes:

• Three written papers in short-answer format, covering Health, Disease and Society
• A practical bench test in operative dentistry, carried out on manikin heads

You must pass every component to move on. All three written papers need to be passed in the same sitting.

Part 2

Part 2 has typically been held in Cork and has three components, each of which must be passed on its own:

• Written short-answer papers in Restorative Dentistry, Oral Surgery and Oral Medicine, and Child Dental Health
• An OSCE testing diagnosis, treatment planning and basic clinical skills
• Clinical vivas with pairs of examiners discussing clinical scenarios

There is no compensation between components, so a strong result in one cannot make up for a weak result in another.

Attempt Limits

This is important. The Council allows a maximum of two attempts at Part 1 and three at Part 2. Repeating Part 2 means retaking all of its components, even ones you passed. And not turning up for a scheduled exam counts as an unsuccessful attempt.

With so few chances, it pays to sit only when you are genuinely ready.

What Makes the IDC Exam Different

Short-answer format

Unlike exams built on multiple-choice questions, the IDC written papers use short answers. You need to recall and write clear, structured responses without options to prompt you. That is a different skill and needs dedicated practice.

Practical and oral components

The bench test, OSCE and vivas test how you work and how you communicate, not just what you know. Practising out loud, under observation and against the clock matters a lot.

Irish and European context

Expect questions that touch on public health, prevention, ethics and professional standards as they apply in Ireland. Make sure your answers reflect local expectations, not just what is standard where you trained.

Building Your IDC Exam Preparation

Start early

Because places are limited and attempts are few, many candidates begin preparing before they even know whether they have a seat. Building a strong foundation early takes pressure off later.

Practise writing short answers

Set yourself timed questions and write full answers. Focus on structure: a clear opening point, key facts in a logical order and a short conclusion where appropriate. Have someone review them for clarity and completeness.

Prepare for the bench test

Regular hands-on practice on a manikin, with attention to preparation design and technique, is essential. Time yourself and ask for honest feedback.

Rehearse OSCE stations and vivas

Practise explaining diagnoses and treatment plans out loud. Work with a study partner or tutor who can play the examiner and ask follow-up questions. Confidence in speaking about your reasoning makes a real difference.

Cover all Part 2 subjects

Restorative dentistry, oral surgery and oral medicine, and child dental health all carry equal importance in Part 2. Do not let a favourite subject crowd out the others.

How a Tutor Can Help

Short-answer writing, vivas and OSCEs all benefit from feedback. It is hard to judge your own written answers or spoken explanations objectively. An IDC online tutor can review your answers, run mock vivas and help you sharpen how you present your reasoning.

What English test do I need?

OET (Dentistry) with at least a B in each module or Academic IELTS with at least 7.0 in each module, unless a waiver applies.

Final Thoughts

The Irish Dental Council exam is demanding, but it is very manageable with the right preparation. Understand the format, respect the attempt limits, practise writing and speaking under exam conditions and make sure your knowledge reflects Irish practice.
