Best way to find out would be to get a major of your choice and see what else you’d have to fulfill. I majored in psychology and took additional courses for a widespread of dental schools which includes genetics, comparative anatomy, biochemistry, biological nutrition, microbiology, precalculus, statistics. (I think as a psychology major, taking additional biology courses definitely helped me stand out when I was able to achieve an A in all additional biology courses as well).
I did it this way because every school requires different pre-requisites. The only other classes I can think of to fulfill most dental schools for myself would be taking calculus and physiology.
You should definitely take anatomy, microbiology, and biochemistry. Many schools require these classes (when you apply, you’ll already have had them completed).
Note: You don’t have to take all those biology courses you claimed missing BUT it will definitely be worth it when you apply so you won’t have any missing courses for different schools you wish to apply to.
