The Corps was established on 13 May 1915, and was initially designated the Canadian Army Dental Corps. It served in World War I battlefields in France and Belgium. The Corps was awarded a Royal Warrant by King George VI in January 1947 in recognition of its exceptional World War II service. The RCDC has subsequently served with distinction in Korea, Afghanistan and many other Canadian Forces missions around the world. The original, polyester tie with the stripes going from left to right – when worn was introduced in the mid-1950s with the assistance of Royal Canadian Dental Corps Association (RCDCA). This current, wider, silk version of the tie introduced in the centennial year of the Corps in 2015, has the stripes moving downwards from right to left, when worn. The colours of royal blue, emerald green and yellow gold are the colours of the Corp flag. The current tie is produced by Guthrie Wood Company which produced tents and other items for Canadian Expeditionary Forces in World War I.
