The College of Dentistry was founded in 1865 as the "New York College of Dentistry." It merged with NYU in 1925. NYU Dentistry is the third oldest continuously operating and the largest dental school in the United States. In 1957, the College moved into its present home on First Avenue, which in 1965 was named the K. B. Weissman Clinical Science Building. In 1978, the Arnold and Marie Schwartz Hall of Dental Sciences was completed. In 1987, New York University dedicated the David B. Kriser Dental Center. In 2002, the Leonard I. Bluestone Center for Clinical Research opened - the only dental school-based research center that provides beds for 24-hour patient monitoring. In fall of 2005, NYU's Division of Nursing moved from the Steinhardt School of Education to form the College of Nursing within the College of Dentistry. In 2015, a new joint 170,000 square foot building for Dentistry, Nursing, and the Bioengineering Institute was opened. In aggregate, the College of Dentistry occupies 27 floors distributed among five buildings.
