text: im a junior in highschool and i want to be a dentist, how do i do it? what classes do i take now and in college, what does it take to join dental school finally - an interesting question.  people apparently don't know that they can search the previous questions instead of asking the same thing that 6 other people asked earlier in the day.  start by going to a good college so you will have a better chance of admission to a dental school.  dental schools are becoming harder and harder to get into, so a good college helps.  it helps to look into the requirements for admission to a dental school and work backwards.  this will help you choose your college major and it might even help you choose your college.  typically, it is easier to match up the requirements for dental school admission with the requirements of a science major and biology seems to be the closest match.  you could be a history major if you wanted to be, but then all of your electives would probably be used up trying to take courses required for dental school admission.  typically, you graduate from college with a bachelor's degree and then start dental school, which is a whole separate entity from college.  some colleges offer combined programs where the really bright and focused student might be able to combine some credits and actually enter dental school before receiving the undergraduate degree.    obviously, you would have to know this well in advance, as it might even determine where you apply to college.  you do not have to disclose this intention as you are applying to the college, but you need to look into the program almost immediately, because it will determine quite a bit about what courses you need to take as soon as possible in college.
