Before you can even think about booking the ORE, there's a number that follows overseas dentists around: 1,600 hours. It's the clinical experience requirement to qualify to sit the exam — and it's also one of the most commonly misunderstood parts of the whole process.
What the 1,600 hours actually represents
The requirement exists because the ORE assumes a baseline of genuine, supervised or independent clinical practice — the GDC wants evidence that you've actually treated patients, not just passed exams and observed others.
What generally counts
In broad terms, clinical experience means time spent actually treating patients — diagnosis, treatment planning, and hands-on procedures across general dental practice. This typically includes:
- General dental practice (NHS-equivalent or private, depending on your country's system)
- Hospital-based clinical placements, where these involved direct patient treatment
- Specialist clinical roles, where relevant
What's more likely to cause problems
Pure observation or shadowing time generally doesn't count toward the clinical hours requirement in the same way as hands-on treatment.
Administrative or non-clinical roles within a dental setting may not count if the role itself wasn't clinical.
Documentation gaps. This is the big one. If your previous employer has since closed, changed ownership, or simply doesn't keep the kind of formal records the GDC is looking for, proving hours retrospectively can become genuinely difficult.
What to do about documentation — starting now
If you're still working in your home country and haven't yet submitted your application, the single most valuable thing you can do today is start gathering and organising documentation now. Specifically:
- Letters from current and former employers confirming dates of employment and the nature of your role
- Any logbooks, case records, or appraisal documents that demonstrate clinical activity
- Contracts of employment that specify clinical duties
The bigger picture for ORE eligibility and GDC registration
Of everything that causes delay in the overseas dentist registration journey, documentation and eligibility issues are consistently among the most common — often more so than the exams themselves. Treating the eligibility and documentation side with the same seriousness as exam preparation isn't being overly cautious. It's simply addressing the part of the process that, when it goes wrong, tends to cause the longest delays.

Clinical experience requirements are set by the GDC and the specific criteria may be refined over time — always refer to the GDC's current guidance for overseas-qualified dentists for the definitive requirements.
