An interdental stimulator for use with human teeth in situ is formed of a stick of clear wood, preferably European sycamore, elongated in the direction of the wood grain and for the most part being substantially rectangular in transverse cross-section. One end portion of the stick is conformed to define two mutually inclined, longitudinally extending, approximately planar side surfaces. This end portion is substantially triangular in transverse cross-section and is truncated to form an inclined planar surface opposite the apex or ridge of the triangular portion. The end portion in transverse cross-section is of a size to be at least partly received in the normal interproximal spaces between human teeth.
