ABSTRACT:
A toothbrush employing a non-pinching resilient twin beam structure to connect the brush handle to the brush head, the twin beam structure having one beam which is wider in cross-sectional width than the other beam in order to prevent soft oral tissue from entering the opening formed between the beams and being pinched between by the interior surfaces of the beams during deformation of the twin beam structure.
