A toothing test stand includes a sample holder and a load generator. The load generator has at least one head, and the sample holder is designed to hold at least one part of a single tooth sample separated from toothing of a gear wheel. The tooth sample comprises a tooth of the gear wheel, and the head of the load generator bears against a flank of the tooth and applies a load to the flank. The head of the load generator is rotatably mounted, and an axis of rotation of the head of the load generator, starting from a course that runs parallel to a flank line of the flank of the tooth, rotates about a surface normal of a contact surface of the head of the load generator and the flank of the tooth.
