A-level subjects for dentistry

What A-levels are needed or essential to become a dentist?

Chemistry, biology and either maths or physics (or both) will keep all dentistry courses open to you.

If you don’t take maths or physics but do take chemistry and biology, a lot of courses could accept you.

If you only take one from chemistry or biology, there's a chance fewer dentistry courses will accept you.

Admissions tests for dentistry 

You'll have to take an admissions test to be accepted onto a dentistry degree. This will probably be the Ucat – but you can read more about university admissions tests here. 

Do I need to do extra study to practice cosmetic dentistry?

You can choose to learn more about aesthetic dentistry, which has become an increasingly popular vocation. This is usually offered as a postgraduate course, meaning you’ll need to have completed an undergrad course in dentistry first. 

It’s worth asking the universities you’re interested in about options if you know this is something you want to specialise in – this could be something you ask at an open day.

What similar subjects can I study to dentistry?

Not sure if you want to study dentistry specifically? You could study these similar courses instead:

• Oral health science – a holistic approach to oral health, more suitable for dental therapists and dental hygienists.
• Dental technology – the creation of custom-made dental appliances.

While similar, these subjects may have slightly different A-level requirements to dentistry – so if you want to keep your degree options open, be sure to check the entry requirements of specific courses before you finalise your choices.
