The Eastman Dental Hospital was based on Gray's Inn Road until it co-located with the University College London ear, nose, throat, balance and hearing services on Huntley Street, London, as the Royal National ENT and Eastman Dental Hospitals in October 2019.

It is a major centre for dental research and the largest provider of postgraduate teaching and training in dentistry in Europe.

[4][5] In 1926, George Eastman donated £200,000 (plus another £100,000 from two other principal benefactors) for the establishment of a specialist dental and oral health clinic for the benefit of poor children of Central London.

[6] The Eastman Dental Clinic was constructed between 1928 and 1930 to the design of Sir John Burnet and Partners[7] and was opened on 20 November 1931 by the American Ambassador.

[10] In 2019, project manager Arcadis and contractor ISG Ltd began work to expand the footprint of the Eastman Dental Hospital site on Gray's Inn Road to enable construction of a new building for the UCL Queen Square Institute of Neurology and a hub for the UK Dementia Research Institute.
