If you're picking A-Levels for dentistry and you've been Googling what you need, the honest answer is that it's one of the most prescriptive degree subjects in the UK. Law tells you to pick what you enjoy and you'll be fine. Economics does more or less the same. Dentistry tells you to take Chemistry, probably Biology, and a third subject, or we can't accept your application.
That sounds brutal, but it also makes the choice easier than most. Two of your three slots are more or less decided for you. What you do with the third one is where most of the thinking actually lives.
The rest of this article walks through what the UK dental schools actually ask for, which third subject makes sense for which kind of applicant, and the admissions-test situation now that the BMAT has gone. Entry requirements shift year on year, so check each school's current course page before you commit to anything specific.
This article was last checked against official university admissions pages on 14 October 2026 for 2027 entry. Admissions tests and offer wording change often, so cross-check each named university's current course page before you rely on any specific detail.
What UK dental schools actually require
There are 16 UK dental schools offering the BDS (Bachelor of Dental Surgery), which is the only route to becoming a UK-registered dentist. The authoritative list sits with the General Dental Council, and you want to check their page for the current accredited schools before you shortlist. Historically the list has included Queen's University Belfast, Birmingham, Bristol, Cardiff, Dundee, UEA, Glasgow, King's College London, Leeds, Liverpool, Manchester, Newcastle, Plymouth, Portsmouth, Queen Mary (QMUL) and Sheffield for the five-year undergraduate courses. Aberdeen and the University of Lancashire (formerly UCLan) also run BDS courses, but only for graduates.
Chemistry at A-Level is required at almost every undergraduate dental school we checked. UEA is the main exception, where Biology or Chemistry is acceptable rather than Chemistry specifically. Biology is required or strongly preferred at most of the others. A few schools (Bristol has historically done this) ask for Chemistry plus a second science rather than Biology specifically, so you want to read each course page carefully because the exact wording moves around.
Offers sit around A*AA or AAA with Chemistry and Biology grade-locked. Grade-locked means a drop to a B in either one on results day can lose the offer, even if the third subject came in at A* and the overall grades meet the target. The exact numbers vary by course and year, so don't anchor on a specific figure without checking.
One worth flagging separately is the University of Lancashire BDS in Preston. It's a self-funded four-year graduate-entry course that needs a 2:1 biomedical degree first, so it isn't an option straight from A-Levels. UCLan also doesn't have an NHS commissioned-student allocation, which means the fees are substantially higher than at other UK dental schools. If you're thinking about it, read the fees information on the course page carefully.
The other thing worth knowing is that there's no central cross-university rulebook on subject guidance any more. The Russell Group scrapped its old "facilitating subjects" list in 2019 and replaced it with its Informed Choices website, which gives general guidance rather than hard rules. Each dental school publishes its own current requirements, and the admissions page is the authoritative source.
The BMAT was retired after the 2023 cycle. UK dental schools now use the UCAT (University Clinical Aptitude Test) in a typical year. If someone's told you to prepare for BMAT, stop, it no longer exists. Admissions tests change frequently, so check each course page for the current test requirement before planning preparation.
A-Level combinations ranked
Because Chemistry and Biology take two of your three slots at nearly every dental school we checked, the only real strategic question is what the third subject should be. The options below run from "opens every undergraduate UK dental school we checked" down to combinations that still get accepted on paper but read as marginal if the Chemistry or Biology grade comes in borderline. If you want to see what else is on the menu before committing, our full list of A-Level subjects for 2026 covers everything available this year.
Chemistry + Biology + Maths (strong, opens every undergraduate course, best Medicine Plan B)
The universally accepted stack. Opens every undergraduate UK dental school we checked and keeps Medicine as a backup, because the medical schools we checked accept Chemistry + Biology + Maths too. Maths is also quietly useful inside the degree itself: pharmacology calculations, biostatistics, and the quantitative reasoning section of the UCAT all benefit from a Maths grounding.
Chemistry + Biology + Psychology (strong alternative)
Also opens every undergraduate UK dental school we checked. Psychology is especially useful for the patient-communication side of the interview, because "why dentistry, not medicine?" is a hard question to answer convincingly without some grounding in behavioural science. It keeps Medicine open at most but not all medical schools, so if Medicine is a serious Plan B, check each one.
Chemistry + Biology + a Humanity (e.g. English Literature) (mid, broadly accepted, read as marginal if borderline)
Still accepted on paper at the undergraduate dental schools we checked. In practice, admissions tutors tend to read a third science or Maths as a slightly stronger signal, and a humanity as a slightly weaker one, when the Chemistry or Biology grade is borderline. Fine if you'll genuinely do better in English Literature than Maths. Weaker if you're picking it to dodge Maths.
Chemistry + Biology + Physics (pivot-friendly, Dentistry + Medicine + Pharmacy)
Opens every undergraduate UK dental school we checked, keeps Medicine open at most medical schools, and keeps most Pharmacy and Biomedical Science degrees open too. The hardest of the four academically, but the one that keeps the widest range of healthcare destinations alive. Pick this if you're genuinely torn between dentistry, medicine, or a pharmacy-adjacent route.
A few combinations to avoid for a dental application. Chemistry plus two non-sciences rules out most schools we checked, because Biology is required or preferred at most of them (UEA being the notable exception). Three sciences without Chemistry rules out almost every school, because Chemistry is required nearly everywhere. And dropping either Chemistry or Biology at AS to "focus on the other" ends the application almost immediately at most schools, even if the plan was to come back strong at A2.

The admissions test situation
UK dental schools require the UCAT (University Clinical Aptitude Test) in a typical year. UCAT is a computer-based test you sit over the summer or early autumn before you apply, covering verbal reasoning, decision making, quantitative reasoning and situational judgement. The structure gets updated periodically, so check the UCAT test format page for the current year. It isn't a Chemistry or Biology test, so your A-Level combination doesn't directly affect UCAT performance, but students who've done Maths and have strong numeracy tend to find the quantitative reasoning section less of a slog.
The BMAT was retired after the 2023 cycle. Any guide you read written before 2024 that tells you to prepare for BMAT for dentistry is out of date. Admissions testing has been in flux across the top universities since 2023, so verify the current test requirement on each course page before planning your preparation.
And a reality check on how the application actually gets weighed. UCAT score, work experience and interview performance all weigh heavily alongside A-Level grades at every UK dental school. A strong A*AA transcript with a weak UCAT and no work experience usually won't get an offer. The subject choice is the first step, not the whole application.
Common misconceptions, cleared up
What to do next
Once Chemistry and Biology are in place and you've picked a third subject, a few things to actually do with the time you have.
Start with the course pages. Check the current page for every UK dental school on your realistic shortlist. Entry requirements, UCAT policies and interview formats shift year to year, and your Year 12 self will trust them more if you've read them with your own eyes. The GDC-approved training providers list is the authoritative source for which dental courses actually lead to UK registration, and it's worth bookmarking.
Book work experience early, because this is the bit that catches people out. Most dental schools expect evidence of exposure to clinical dentistry by Year 12 at the latest: shadowing a dentist, time in a hygiene practice, a few days in a hospital dental department. Competitive applicants usually have more than one setting on their CV, and ideally some patient-facing experience in there too.
Start UCAT preparation in the summer of Year 12. UCAT is time-pressured and the question types take practice to recognise, so a few weeks of structured preparation is standard for strong scorers rather than something you do in the week before the test.
And for the Chemistry and Biology grounding that will carry you through BDS, our complete guide to AQA A-Level Chemistry and complete guide to AQA A-Level Biology cover what both A-Levels actually look like and what to expect from them.
One last thing. This article is a starting point. Dental school admissions change frequently and the stakes are high, so treat each dental school's own course page as the final word on anything specific.
