Should I go the Dental or Medical way? Doctor or Dentist?

Look, I'm not going to lie to you. My first reason for wanting to do a health related profession was the money. But as I kept looking, I actually got pulled in and now my level of interest in science has skyrocketed. I am faced however with a dilemma. I cannot decide whether I want to go to Dental or Medical school. I am fascinated with surgery as well as internal medicine, but the fact that Dentists only have 4 years of dental school before being able to practice is extremely luring. I don't want to spend all my life in school, but I love Medicine and money as well. What do I do??
