An applicator device for the application of paste directly upon the teeth, particularly in the interspaces between teeth intended to be used by the dental profession or when cleaning the teeth at home. The object of the invention is to create an applicator device of a simple design economically so that it need not be refilled but may be discarded after use. The device should also be easy to handle and shaped such that its tip can reach each and every interspace. The device comprises an integrally formed plastics material tube having a comparatively wide, compressible handle portion defining an internal paste container, an adjoining comparatively narrow and quite long conduit portion, and a laterally directed tapering nozzle portion at the end of the conduit portion through which portion the paste may be discharged into the interspaces between teeth.
