A hand-held dental instrument has an elongated handle and a blade shaped like a human foot. The blade has ankle, arch and instep edges that curve inwardly and are of different depth and curvature. There is a shank portion between the blade and the handle with the angles between the shank and the handle and between the shank and the surface of the blade preferably being 150° and 120° respectively. These angles allow the user to reach all areas of the mouth. The blade is thin enough to allow the instrument to reach between the lower front teeth.
