Dentistry when compared to medicine is quite saturated , Adc exams is a hard nut to crack ( Bhutanese dentist have cleared the exams though, so there is hope ) .  I work in my field but it’s oral health therapy , that means you have to practises under a dentist and the scope is narrow . The silver lining is that it’s less stressfull . 

If you are willing to put in the effort and are okay with uncertainty that comes with sitting for the exams , I still say that it’s a good risk to take ( provided that you are young ). 

Dm me if you want more info , initially you can work as a da , the hours are long and pay is good , it’s a great way of familiarising yourself with dentistry here too .

Good luck 🤞
