This invention consists of an ordinary toothbrush having a convex brush arranged at the end of the handle, crosswise to it, in a difierent plane and fronting the other brush, so that.

handle at one side of it and fronting the brush B, as above stated, so that when the brush end B is used as a handle and the convex brush put in the mouth it applies to the teeth at the inside better than any other brush by reason of its convexity and relative arrangement with the handle.
