Dentistry is one of the most prescriptive subject-choice decisions in UK higher education. Where law and economics tell you "pick what you enjoy and you'll be fine", dentistry tells you "take these specific sciences or we literally can't accept your application". Chemistry is required at almost every UK dental school we checked, and Biology is required or strongly preferred at the majority.
This guide walks through what the UK dental schools actually require, which combinations keep every school open, which third subject makes most sense, and what's changed recently with admissions tests (the BMAT was retired after 2023, and dental-school entry now uses the UCAT). Entry requirements change year to year, always verify the current year's offer on the specific university's course page before you commit.
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, the only route to becoming a UK-registered dentist. The authoritative list of training providers is published by the General Dental Council; check the GDC page for the current year's accredited schools before shortlisting. Historically this 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 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 course we checked. The main exception is UEA, which accepts Biology OR Chemistry rather than requiring both or requiring Chemistry specifically. Biology at A-Level is required or strongly preferred at the majority; some schools (Bristol has historically done this) ask for Chemistry plus a second science rather than Biology specifically. Always check the current year's wording on each course page because the detail varies.
Typical offers sit around A*AA or AAA with Chemistry and Biology grade-locked (meaning a drop to a B in either on results day can lose the offer even if the other grades are met). Specific grade requirements vary by course and year; check each school's current offer before anchoring on a number.
The University of Lancashire (formerly UCLan) in Preston is worth flagging: its BDS is a self-funded four-year graduate-entry course that needs a 2:1 biomedical degree, so it isn't an option straight from A-Levels. UCLan does not have an NHS commissioned-student allocation, so fees are substantially higher than at other UK dental schools. If you're exploring UCLan, read the fees information on the course page carefully.
University admissions pages are now the authoritative source for subject guidance, the Russell Group scrapped its old "facilitating subjects" list in 2019 and replaced it with its Informed Choices website, which gives general guidance only, and there is no central cross-university rulebook any more. Each dental school publishes its own current requirements.
The BMAT was retired after the 2023 cycle. UK dental schools now use the UCAT (University Clinical Aptitude Test) in a typical year. If you've been told to prepare for BMAT, stop, it no longer exists. Admissions tests change frequently, so always check each course page for the current year's test requirement before planning preparation.
A-Level combinations ranked
Because Chemistry and Biology take two of your three A-Level slots at nearly every dental school we checked, the only real strategic question is what the third subject should be. The combinations below are ordered from "opens every undergraduate UK dental school we checked" through to combinations that remain accepted but tend to be read as marginal if the Chemistry or Biology grade is borderline. Our full list of A-Level subjects for 2026 covers every option available this year if you want to explore beyond these core recommendations.
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 plan, because UK medical schools we checked accept Chemistry + Biology + Maths. Maths is also quietly useful inside the degree itself (pharmacology, biostatistics and the quantitative reasoning section of UCAT all benefit).
Chemistry + Biology + Psychology (strong alternative)
Also opens every undergraduate UK dental school we checked. Psychology is particularly useful for the patient-communication framing that comes up in interviews, "why dentistry, not medicine?" is harder to answer convincingly without some grounding in behavioural science. Keeps Medicine open at most but not all medical schools (check each).
Chemistry + Biology + a Humanity (e.g. English Literature) (mid, broadly accepted, read as marginal if borderline)
Still accepted at the undergraduate dental schools we checked on paper. 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 perform better in English Literature than Maths; weaker if you're picking it to avoid 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 combinations academically, but the one that keeps the widest range of healthcare destinations open. Pick this if you're torn between dentistry, medicine or a pharmacy-adjacent route.
Combinations to avoid for a dental application: Chemistry plus two non-sciences (rules out most schools we checked, since the majority of UK dental schools require or prefer Biology on top of Chemistry; UEA is a notable exception), three sciences without Chemistry (rules out almost every school we checked, since Chemistry is required nearly everywhere), and dropping Chemistry or Biology at AS "to focus on the other" (ends the application immediately at most schools).

The admissions test situation
UK dental schools require the UCAT (University Clinical Aptitude Test) in a typical year. UCAT is a computer-based test taken over the summer or early autumn before you apply, covering verbal reasoning, decision making, quantitative reasoning and situational judgement (the test structure is updated periodically; check the UCAT test format page for the current year). It's not 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 challenge.
The BMAT was retired after the 2023 cycle. Any guide written before 2024 that tells you to prepare for BMAT for dentistry is out of date. Admissions testing has been in flux since 2023 across the top universities, always verify the current year's test requirement on each course page before planning preparation.
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 will usually not get an offer. Treat the subject choice as 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 chosen a third subject:
Check the current course page for every UK dental school on your realistic shortlist. Entry requirements, UCAT policies and interview formats change year to year, and your Year 12 self will trust them more if you've seen them with your own eyes. The GDC-approved training providers list is the authoritative source for which dental courses lead to UK registration, and is worth bookmarking.
Book work experience early. Most dental schools require evidence of exposure to clinical dentistry (shadowing a dentist, hygiene practice, hospital dental department) by Year 12 at the latest. Competitive applicants typically have multiple settings on their CV, including some patient-facing experience.
Start UCAT preparation in Year 12 summer. UCAT is time-pressured and the question types take practice to recognise. Several weeks of structured preparation is typical for strong scorers.
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.
Finally: this article is a starting point. Dental school admissions change frequently, and the stakes are high. Treat the authoritative source, each dental school's own course page, as the final word on everything specific.
