constructive arrangement introduced in tongue sanitizer, more precisely it is sanitizer (1) of the type used for the mechanical removal of the tongue coating； said sanitizer (1) comprises a thin single piece (2) made of a rectangular shaped flexible polymer forming flat surfaces (2a) and (2b) and side walls (2c) and (2d), which in turn are tapered. with central portion of the part (2)； the tapered area has material accumulation forming a reinforcement base (bf) whose peripheral walls (2c1) and (2d1) are arched and opposite to each other； at the edge of the wall (2c1) multiple recesses (r1) and undulating protrusions (s1) are practiced forming a serrated sector (sr) specially developed for friction on the dorsal (sd) surface of the tongue (l) for mechanical cleaning. from the coating； the wall (2d1) opposite the serrated (sr) has a smooth surface (s2) serving as a maintenance area during lingual cleaning； the end portions (2e) of the slender part (2) are identical, being formed by oblong sectors (2e1) where bending lines (d1) are practiced to compose angled inclined planes (?) in relation to the flat surfaces. (2a) / (2b)； the faces (f1) of each oblong sector (2e) have a slight anatomical recess forming an area to support the user's fingers.disposição construtiva introduzida em higienizador de língua, mais precisamente trata-se de higienizador (1) do tipo utilizado para a retirada mecânica da saburra lingual； dito higienizador (1) compreende peça única delgada (2) confeccionada em polímero flexível com formato retangular formando superfícies planas (2a) e (2b) e paredes laterais (2c) e (2d), as quais por sua vez, apresentam-se afuniladas com porção central da peça (2)； a área afunilada apresenta acúmulo de material compondo uma base de reforço (bf) cujas paredes periféricas (2c1) e (2d1) apresentam-se arqueadas e opostas entre si； na borda da parede (2c1) são praticadas múltiplas reentrâncias (r1) e saliências (s1) onduladas compondo um setor de serrilha (sr), especi
