If you wish to pursue dentistry, know that in the US, it is not a college program. American dentistry schools are post graduate schools. This means you get your Bachelors degree first and then apply to a dental school afterward. What you choose as your major (concentration) at college is not absolute although many major in one of the sciences since Dental school requires very good science skills, as you can imagine.
Do some more research on what that track entails. There’s also a pre-dentistry forum here too
