A hygienic tongue scraping and massage instrument for freeing and removing pathogenic foreign matter entrapped in upper surfaces of the tongue comprises a pair of elongated handles and a generally straight cross bar formed with a scraping edge and having opposite ends connected respectively to forward ends of the handles. Connections of the opposite ends with the forward ends establish corners so that the scraping edge extends continuously along the cross bar to intersect the corners. Each handle is preferably rectangular in cross section with the cross bar being of triangular cross section and tapered downwards to form the scraping edge. The corners are generally sector or triangular shaped so that the handles and cross bar are sufficiently rigid to resist torsional flexing of the handles and minimize the tendency of the scraping edge to partially disengage the tongue as the instrument is brought forward by the user out of the oral cavity.
