The utility model relates to a interdental brush, which comprises a brush rod and a handle.The brush rod has an exposed section, a buffer section and an anti rotation inclined section, the outer circumference of the exposed section has bristles, the buffer section is connected between the exposed section and the anti rotation inclined section, the anti rotation inclined section is the end of the brush rod and is in a single straight line shape, the anti rotation inclined section and the buffer section are inclined rather than collinear to form a bending part between them, and the anti rotation inclined section is One end of the buffer section is connected in a flat shape.The grip covers the buffer section and the anti rotation inclined section, the grip has a core part and a surface part, the core part at least covers the buffer section and the anti rotation inclined section, and the core part has an opening for the anti rotation inclined section and at least a part of the bending part to be exposed, and the surface part at least covers the core part and the anti rotation inclined section.一種牙間刷，係包含一刷桿及一握柄。該刷桿具有一外露段、一緩衝段及一防轉傾斜段，該外露段之外周面具有刷毛，該緩衝段連接於該外露段及該防轉傾斜段之間，該防轉傾斜段為該刷桿的末端且呈單一直線狀，該防轉傾斜段與該緩衝段係呈傾斜而非共線，以於其間形成一彎折部，且該防轉傾斜段在連接該緩衝段的一端係呈扁平狀。該握柄包覆該緩衝段及該防轉傾斜段，該握柄具有一芯部及一表部，該該芯部至少部分包覆該緩衝段及該防轉傾斜段，且該芯部具有一開口供該防轉傾斜段及該彎折部的至少一部分裸露，該表部至少部分包覆該芯部及該防轉傾斜段。
