Information Systems vs. Biology and going into Dentistry?

I am curious about the outcomes for both majors/professions. My original thought was to go into dentistry, but having to go through 8 years of school plus residency and the enormous debt piled on after seems unappealing. I am very passionate about both, as I love what dentistry is about and I am very into technology as my childhood grew around it. I guess my question is, if I was equally passionate about both, which would have the better pay/work schedule? I know dentists make more, but I know a information systems can eventually make 100k+ if they work for it.
