It's amusing the number of posters we've had on here recently who seem to think that we just spend the first semester of dental school learning to count the teeth and the other 3 1/2 yrs are one giant drill-fest. The amount and level of detail that you will be asked to learn about the human body is beyond your comprehension at this point.
Actually, almost all of the "crap" you learn as a bio major will be relevant to your dental course work. That being said, it will be only a miniscule part of what you will be learning. One of the most difficult upper level courses I took in undergrad was cell biology - just about everything I learned in that 4 credit, full semester class was covered on the first test of dental school biochem... only in more detail!!! 😱
I would agree with this advice, but only because I believe that 4 yrs is too much time to spend on something you don't enjoy. A bio major will ABSOLUTELY give you a leg up in dental school, but there is no way I would ever recommend that someone give up four years of their youth doing something they hate for that advantage.
Many degrees are an end in themselves, but biology is pretty much just a ticket to more school. Work towards something you could see yourself doing if you change your mind about dentistry. Life is short; you might as well enjoy it.
BTW, hope I didn't offend you RaiderNation.
