You could try making a T-chart listing the pros and cons of each. Here's what I put on mine when I had to make the same decision as an ignorant undergrad. If I'm off on any of this stuff I hope that dental students and doctors will correct me or add to the list.
A few pros for Medicine:
1. lots of possibilities as far as what you actually end up practicing (more specialities, more research, etc.)
2. slightly more public status. This is sort of obvious, but there are at least two ways you can measure it: a.) # of television programs romanticizing the practice/ lifestyle of medical doctors b.) watch the reactions of people when you tell them you are going to medical school vs. dental school...just try it.
3. although most dentists and physicians are on par financially, medicine could possibly be more lucrative than dentistry
4. Lots of different scenarios everyday, absolute necessity to keep up with current literature, while most of the dentists I know toss the scholarly journals in the can just as soon as they get them.
5. get to save lives more directly, at least if you're working in the ER; ie, you might derive a greater sense of purpose and meaning from your career in medicine.
6. more resources/ funding, especially at med schools, while some dental schools are so short on funding they have to close (loyola, northwestern, georgetown...)
Cons of medicine:
1. Insurance/ hmo/ppo/corporate hospitals telling you who you can/cannot treat and how with what- decrease in autonomy
2. public recognition may inflate your ego and make you believe you are more important than you really are. (not necessarily, but it happens) I just knew that so much recognition might turn me into a jerk. Prevention is the best medicine!
3. residency can put a huge strain on marriage or relationship
4. being "on call" (if you are working for a hospital or group practice) reduces the activities you can engage in or where you can go on the weekend
5. typically less autonomy due to insurance, hospital and urgent need for care
6. Very stressful- some people are great stress managers, but I prefer less than more. I don't want to feel responsible for someone dying. I'm sure I'd eventually grow calloused, but still...
7. Sometimes the longhours of medicine can send the message to the family that work is more important- whether its true or not. I want to be a husband and dad before doctor so and so.
Pros for Dentistry:
1. More autonomy
2. Great pay
3. Little interference (at least at present) from insurance companies
4. Flexible schedule (see autonomy)- I anticipate working anywhere from 3-6 days a week once I am established in my practice
5. leave work at the office at 4-5 pm, then come home to the fam/ and more time to pursue my own hobbies like painting, backpacking, writing and gardening
6. don't have to deal with life and death situations as frequently
7. opportunities to specialize (albeit, fewer than medicine)
8. predictable workday
9. continuing education seminars in cabo!
10. opportunities for humanitarian aid/ and a dire need here in the states to provide oral health care to underserved communities (medicine might have lots of opportunites for public service too, so not mutually exclusive here)
11. Very hands on--as I mentioned before I like to paint/draw/sculpt, so I like to work with my hands, but Dentistry pays more
12. Less public oggling helps keep my head from bursting from an overinflated ego. I could see that happening to me if I pursued medicine...it would be tragic
Cons of dentistry
1. Its not fun to be called a premed washout or fake doctor. It can be hurtful even if its not true, just because of the hostile or condescending nature of the comment. So you've got to be confident with yourself and happy with dentistry in order to not develop an inferiority complex. Or if your into public admiration be a doctor, lawyer or american idol.
2. It can be boring if you are just drilling and filling all the time, although this is rarely the case
3. It may be a little harder than medicine to go home each day and say, "I really made a difference in someone's life today" even though you likely did
4. dental schools are not as well funded as med schools
5. reported high suicide rates among denists (I suppose they don't find real meaning or purpose in their lives-"existential vacuum"? is what victor frankl would call it, or maybe they have an inferiority complex to medical doctors) I don't know, but I;m sure there is something to be reckoned with there
6. a lot of patients, especially those of GPs are in dread and expect excruciating pain at the very site of your face as a dentist. that could get emotionally taxing after a while.
7. Less need to stay current with literature; consequently, it could be less challenging/intellectually stimulating than you care for
But at the end of the day, dentistry is a good job that pays well. For me, dentistry was not a "spiritual calling" like so many premeds claim to have had. It is just a great career that allows me to be have a life first.
