More than 60 dental schools are accredited in the United States, but not every school fits every student. The American Dental Association conducted surveys to find out which schools are the biggest, the most competitive and offer the best instruction. Students can weigh the data as they consider which schools might best meet their needs.

Think Big

New York University’s College of Dentistry had 239 students enroll in the 2010-11 school year, more than any other accredited program, according to the ADA's most recent survey. The school trains 1,800 people a year, including dental hygienists, nurses, undergraduates and graduate students, according to data from 2013 on the NYU website. Boston University had the second-most enrollees in 2010-11 with 190, and more applicants than any school with 5,546. The school offers undergraduate and doctoral programs for its 700 students, according to its website in 2013.

The Best of the Best

The Arizona School of Dentistry & Oral Health at A.T. Still University of Health Sciences is more selective than any other school in the ADA survey. Only 2.2 percent of applicants were accepted in 2010-11, the latest data available at time of publication; 69 students made up that class. The school offers a Master of Public Health degree in addition to a basic dental degree. Marquette University accepted only 2.5 percent of its applicants in 2010-11. The school has a patient- and student-centered philosophy and is the only dental school in Wisconsin, according to its website.
