A tooth display measurement device includes a measurement portion, an inner surface and an outer surface. A tooth rest platform projects outwardly from the inner surface. The tooth rest platform is spaced between the upper end and the lower end, and ruler markings are printed or otherwise affixed on the outer surface. A a handle projects from the lower end of the measurement portion. The device assists in an accurate reading of tooth display as the measurement portion is inserted between the lip and the teeth of the user with the tooth rest platform abutting the biting edge of the tooth to be measured.
