In carrying my invention into effect, I prefer to have the device in the general shape of a well known form of tooth brush, but with several of the bristles replaced by a downwardly projecting lip carrying a yielding scouring jacket of fibrous material- In the drawings forming part of this specification,'Fig. 1 is a side view of a device embodying my improvements.

The handle 1 of the device is not unlike that of a well-known form'of tooth-brush, having preferably a few bristles 2 spaced from its end 3. Between the bristles and this end, there is formed a lip 4, either integral with the handle orsuitably' attached thereto; the'same being approximately rectangular in outline*asviewed' from the side, as illustrated in Fig. 2, but having itsedges' Upon this li is slip ed a cap or jacket. 5, composed of fabric, elt,', chamois, skin or other soft fibrous material; as shown in Fig. 6. Lamp-wicking I find to be a most excellent fabric for the purpose.
Parallel with and spaced from the lower marginof the cap or jacket 5 is a line of stitches 6' for creating a thicker scouring cushion 7 thereat.

I find it to be necessary to make the l-ip and its fibrous covering 5 quite deepfto enablefite to reach into the convolutions and recesses of'the dentitions especially those of the plate of a setof upperteeth.
The bristles 2 are preferably provided in order to permit the cleanser to reach into and dislodgeany accumulations between the teeth. The fibrous covering 5 is not only of cleaning sets of false teeth, for people having being used to give great value in but it is equally useful natural teeth, the same possible to bris'tles alone. Especially is this true for young children whose ms are so tender as toren'der theuse of a ristle toothbrush jhighly injurious.
