A toothing testing apparatus includes at least one pair of measuring disks or balls of a certain diameter which are introducible into respective substantially diametrically opposed tooth spaces of a testpiece, and measuring probes each including a base part and a measuring part elastically secured to the base part and rockable relative thereto, for measuring the distance between the measuring disks or balls of said at least one pair, the measuring part having one of the measuring disks or balls attached thereto and the base part being housed in or against a stationary part of the testing apparatus. The measuring disks or balls are symmetrically positioned and automatically centered in the tooth spaces to be measured, and the depth of penetration of the measuring disks or balls into the tooth spaces is measured by the testing apparatus.
