Sheffield University Dental School. Sheffield Dental School was first established in the late 1890’s. Sheffield University has been awarding a degree in dental surgery since 1929. The School is linked to the Charles Clifford Dental Hospital where the majority of the clinical instruction takes place. When the School and Hospital underwent a multi-million-pound refurbishment between 2008 and 2010, the School was renamed Sheffield University School of Clinical Dentistry. The Sheffield University Dental School tie dates back to the 1990’s
