What should you study for in school to become a dentist?

Educational preparation to become a dentist should include lots of science. Biology, chemistry( inorganic, organic, bio), physics, and anatomy should be emphasized.

In addition, courses in business (accounting, management, marketing, etc) will be helpful if one becomes a private practice dentist.

Courses that help one understand human nature and behavior will also be very useful (psychology, comparative religions, cultural anthropology, etc).
