The invention provides a dental tool for insertion between two adjacent teeth to provide a-traumatic separation of adjacent teeth of a human being. The tool comprises a base, a first leg for placement in a first gum pocket and for abutting a first one of the two adjacent teeth and a second leg for placement in a second gum pocket and for abutting a second one of the two adjacent teeth. The first and second legs are elongated and extend from the base in an oblong direction towards an end. The legs are separated with an interspace between them for accommodating gum tissue. The invention further provides a method for providing a-traumatic separation of two adjacent teeth of a human being during dental restoration.
