<p>Yes, many people start pre-med and then change to pre-dent. However, I believe that sequence is more likely due to the lack of creativity, exposure, and knowledge to many career choices of most HS students. Whether prestige and prominence plays into it, I'm not entirely sure, but pre-med is a stereotypical entering major. People who have no business being pre-med come in as freshman year being just that because they have no clue what they really want to do. </p>
<p>And just because interest ebbs unidirectionally, that doesn't mean that individuals who go to dental school aren't strong enough students to enter medical school. In fact the two most insanely intelligent people I know are both in dental school (one graduated in may), and could have just as easily excelled in medical school, but had a passion for teeth. </p>
<p>Further, given that there are significantly fewer spots in dental schools compared to medical schools, the competition for dental schools is nearly as intense as it is for medical school. I believe there are only about 4,000-5,000 spots in dental schools compared to nearly 16000 spots in medical schools. </p>
<p>Finally, Luck brings up a key point about the salaries in terms of length of training. Compound that with the fact that most dentists have much, much, much better hours than nearly any field of medicine, their salaries are more valuable in non-monetary terms. A lot of dentists I know only work 3.5 to 4 days a week, have no call, and minimal malpractice premiums.</p>
<p>As for specialized dentistry fields, orthodontists certainly have the potential to earn far more money than most fields of medicine if they run their practice right. My personal orthodontist's practice is probably bringing in close to 3 mil a year gross. He's got 4 offices, 4 orthodontists working directly under him, and he works two and half days a week.</p>
<p>Honestly if anyone can stand to look at teeth all day (which I absolutely can't) and want to be in the medical field, dentistry is probably the smartest choice possible. Comparable benefits to being a doctor with little of the hassle.</p>
