its easier to get into dental school and the life of a dentist does sound awesome. you certainly cant go wrong, but...
you have a much harder time once you are in school compared to being in med school. if you are looking for "lifestyle" careers like this, making over 200k with good hours means you are a dental specialist meaning you completed extra years of training, and were at the very top of your class, or went to harvard or columbia or a school where nearly all of the students specialize.
on the other hand in medical school you can basically walk into a 200k-300k job like anesthesiology or pain management or something like that. Low competition to get into these programs and high income.
so i guess in the end medical school assures you more of this kind of lifestyle if that is what you are looking for. Dental school will allow it but its not over when u walk in the door u have to earn it in class. And the money isnt an issue either way in my opinion
this used to be a debate to me too, i was going to go dental but got pulled off of the wailist at the last second to MD school and i am glad it happened.. im thinking about anesthesiology
