How Many Years Of University Before You Can Become A Dentist?

I am doing a project in school about the job of your dreams and i’m intrested in becoming a dentist- well actually an orthodontist. I have found out that you need to go to university to become a dentist before you can take a college course on orthodontics but i’m not sure how many years of university do you need to become a dentist. what about an orthodontist?
