I think when people look at dental schools as a back-up plan is very insulting to the dental students and the dental community. There are people who truly want to become a dentist because they believe in what a dentist can do. And there some who just want to go to dental school because they cannot get accepted to medical schools. In a way, I am glad that dental schools are getting more competitive nowaday so we can eliminate some people who do not have the sincere interest in dentistry. And for people who could not figure out what to pursue, dental or medical, why don't you volunteer in a dental office or a hospital for an extended period of time to test out your commitment first? Why apply to both fields? If I am an adcom, I would not even consider people who are applying to many fields at once. Their actions show me no comittment what so ever. If you really want to become a medical doctor, and the medical schools do not accept you on the first try, why don't you reapply and reapply? Don't just apply to both dental and medical schools to test out your luck. The seats in the dental and medical schools should be given to people who truly earn it (being good in science is not the only one good reason for you to earn the spot).
