what? there are PLENTY of us who had the option to go to either medical or dental school and chose dental. and by the way, MANY of our physicians in the US are graduates of schools in the caribbean, australia etc. where all they do is pay a "donation" to get in that have links with US hospitals to do residency here and get their US license, whereas there are no programs like this for dentists since no non-US schools have accreditation or these types of links aside from la salle.
i don't know how many people chose to go into dentistry because they couldn't get into medicine, but it's highly offensive to suggest dentists are dentists because they couldn't be physicians for whatever reason. Whoever is doing so is going to be a horrible dentist.
