A dental measuring device can be used to measure the separation of reference positions on a patient's upper and lower jaws to assist in the construction of dentures. The device has two elements which slide longitudinally relative to each other with a pointer on one and a scale on the other. The elements have projecting arms. The sliding elements can be reversed so that in one position the arms point in the same direction for measuring the separation of specific points on the patient's nose and chin, and in a second position the arms point in opposite directions for positioning beneath the patient's nose and chin.
