What GCSEs Do You Need to Become a Dentist?

If you’re considering a career in dentistry, you’re probably wondering what qualifications you need to set you on the right path. In this article, we’ll break down what GCSEs you need to be a dentist, as well as some optional GCSEs that can help strengthen your application. You’ll also learn the next steps to take after GCSEs, such as choosing A-levels and gaining relevant work experience. By the end, you’ll have a clear idea of what you need to do to start working towards a successful career in dentistry!

For most universities, a minimum of around six to eight GCSEs is required in order to consider you for dentistry. Often, you will need to pass at least six or seven of these with high grades i.e. grade 6 (B) or above. However, some universities may require a grade 7 (A) or above in a certain number of subjects.

For example, if you wanted to study dentistry at The University of Manchester, you would need:

• At least seven GCSEs at grade 7 or above

• English Language, Mathematics and at least two science subjects at GCSE minimum grade 6

  • If Dual Award Science or Core and Additional Science are offered, the minimum required is 66 (BB)

It is important to note that requirements can vary greatly between universities, so always check their dentistry entry requirements if you already have a specific university in mind. You can find a list of the most up-to-date 2025 entry requirements (including GCSE requirements) for all UK and Ireland dental schools in this booklet, produced by the Dental Schools Council.

Core GCSEs for Dentistry

To become a dentist, some GCSE subjects are non-negotiable. These core subjects form the foundation of the knowledge and skills you’ll need in the profession. It’s important to get the highest grades you can in these areas, so you’ll want to focus plenty of your revision time preparing for the following exams:

Sciences

A solid understanding of science is essential for aspiring dentists. Most universities require at least two science GCSEs, typically Biology and Chemistry. These subjects lay the groundwork for what you’ll learn at A-level and beyond.

Biology helps you understand the human body, especially the mouth, teeth, and gums, while Chemistry can introduce you to some of the substances and processes used in dental treatments.

You’ll need at least a grade 6 or 7 in these Science GCSEs, depending on the university. The University of Birmingham requires a grade 8 or above in Biology and Chemistry!

Maths

Maths is another must-have subject for dentistry. A good grasp of mathematical concepts is essential for problem-solving, measurements, and data analysis in dental treatments. Again, you’ll need at least a grade 6 in GCSE Maths, though many universities expect higher grades. A strong performance in Maths can also prepare you for subjects like Physics at A-level, which can sometimes be a requirement for dentistry courses.

English

Strong communication skills are key in dentistry, and GCSE English Language is where this begins. Dentists must be able to explain treatments clearly to patients and write reports on their findings. Universities often require a minimum of grade 6 in English Language to ensure candidates can meet the high communication standards required in the profession.

Optional GCSEs for Aspiring Dentists 

While the core subjects are essential, there’s flexibility when it comes to optional GCSEs. These subjects may not be mandatory, but they can help you develop transferable skills that will benefit you in dentistry.

Psychology

Psychology can be a valuable optional subject. Understanding human behaviour and how patients react to pain, fear, and stress is essential for dentists. A background in psychology can help you manage patient interactions more effectively, especially when dealing with anxious individuals.

Business Studies

Another useful subject could be Business Studies. If you plan on opening your own dental practice in the future, having a basic understanding of business principles will come in handy. It’s useful for managing a business, dealing with finances, and ensuring the smooth operation of a clinic.

What would an actual dentist say?

We asked professional dentist Dr Amy Vickers what her experience was when she was choosing her GCSEs and this what she had to say:

“I knew to get into dental school I needed to make sure all of my GCSE results were very high grades, but also I needed to demonstrate that I was a well rounded individual, so I chose a wide spread of GCSEs but also played it safe with subjects I knew I would get a high grade. 

“In hindsight taking art might have demonstrated the manual dexterity needed for dental work, but I was concerned that I risked only getting a pass and not a high grade. Psychology was not offered at my school at the time, but if it was it would have been useful as an excellent basis for further study in any healthcare field.”

-Dr Amy Vickers, Clinical Director of Dental Services at City Health Care Partnership CIC

Beyond GCSEs – What’s Next?

Once you’ve secured the necessary GCSEs, the next step is choosing relevant A-level subjects. Typically, universities expect students to take Chemistry and Biology at A-level, with some also requiring Maths or Physics. These A-levels will prepare you for the rigorous science-based curriculum you’ll experience when studying for a dentistry degree.

Most universities also require you to take the UCAT (University Clinical Aptitude Test), a two-hour computer-based aptitude test that assesses your ability to think critically and solve problems. It’s important to note that preparing for the UCAT will require extra time outside your regular studies, so dedication is key.

The Importance of Work Experience 

In addition to your academic qualifications, work experience is highly valued in dentistry. Shadowing a dentist or working in a dental practice shows universities that you’re committed to the profession. Start looking for work experience opportunities as early as possible, even during school holidays in Years 10 and 11. Observing how dentists work will not only strengthen your UCAS application but also give you valuable insights into the career.

Don’t forget, extracurricular activities, such as volunteering or attending science clubs, can also enhance your personal statement when applying for university. Admissions teams like to see that you’re well-rounded and actively engaged in learning outside of the classroom.

Frequently Asked Questions

Can I Become a Dentist With Bad GCSEs?

It’s possible, but it may be more difficult. Universities expect high grades, especially in core subjects like Maths, English, and Science. If you don’t meet the minimum requirements, you might need to retake certain subjects (although it is important to note that not all universities accept resits).

How Many GCSEs Do You Need to Become a Dentist?

Most universities require at least seven GCSEs with high grades. It’s important to check individual university requirements as they can vary, but a strong performance across at least seven subjects is the standard.

Do Universities Look at GCSEs for Dentistry?

Yes, universities consider GCSE grades when reviewing dentistry applications. They look for strong grades, particularly in core subjects like Maths, English, and Sciences, as a way to assess your academic foundation before moving on to A-level and university-level study.
