The flexible member 13 has first and second sides and a central bristle support portion 20A disposed between first and second outer bristle support portions 20B, 20C. The flexible member also has an elastic portion interconnecting the central bristle support portion to the first and second bristle support portions along lateral edges thereof. The toothbrush further includes a pair of handle extensions 14A, 14B for supporting the flexible member at the first and second sides thereof such that the flexible member is free to flex between first and second shapes when stressed. An array 12A of first bristle tufts is attached to the central bristle support portion. First and seccond arrays 12B, 12C of second bristle tufts are attached to the first and second outer bristle support portions, respectively, and are aligned in parallel relation to the array of first bristle tufts.
