"If you have your eye on a career as a dentist, a Pre-Dentistry program might be what you’re looking for. Pre-Dentistry, like all pre-professional programs, offers focused coursework in both general education and areas more specific to your intended field. You’ll take courses in the natural sciences like biology and chemistry. You’ll take science laboratories to get hands-on experience with research and documentation. You’ll take courses in communication, social sciences, and humanities. Ohio State University suggests volunteering or working in a dental office during your undergraduate years—a great way to make sure you want to pursue a dentistry career after graduation.
Although you won’t specialize until you’re on your way to becoming a dentist, it doesn’t hurt to be aware of what’s out there. Dentistry includes many areas of expertise, including orthodontics, pediatric dentistry, and oral surgery. Your own interests and concerns will help you to eventually choose a specialty.
You should know that most dentistry programs don’t require a Pre-Dentistry major, just as medical schools don’t always require pre-med. Keep in mind that good grades and dedication in all your courses are the best preparation." (Princeton Review)
