Dentist or rn, I'm confused. Please help!!?

I am really having a hard decision on deciding to either go for nursing or dentistry. I actually was in an rn program and I'm a patient care tech and after working as a Pct, I'm bored and ready to do something new! I failed my nursing course by 3 points, I was mad due to failure but I know me, if I want something I'm going to get it. While I was doing my clinicals, I was not amused, I was bored, and couldn't stand it. The main reason I tried to pursue nursing was to pay for dental school because that is just way too expensive. But now since plan A didn't work, I'm thinking of going with plan B, n go straight for dentistry. But I compare and contrast the two, the major con for dentistry is debt and it's longer, for rn, it's more stressful, less pay, taking orders from a mD. I mean all jobs have their pros and cons. N no I don't want to do dentistry for money, I like to work with my hands, solve problems, not be too stressed, I don't want to take orders from no one, I'm tired of that, n I want to be successful but yet different. I'm just scared of the time frame and payin for dental school because I'm 25 n I don't want to be 35 n have nothing, I still dont have a degree but if I go for dentistry I would have a BA in a year. Ok I think I answered my own ?.. But if there is anything I didn't mention about the pros n cons of both, please let me know.
