A toothbrush according to claim 12, wherein the integral link is made so thin that it can flex completely freely or snap or shear when the toothbrush is used. 15. A toothbrush according to claim 1, wherein the neck and handle are provided with respective torsion parts, at least one of which is resilient, and such that when the neck and handle rotate relative to each other about the rotation axis the respective torsion parts bear upon each other as a result of the relative movement of one torsion part circumferentialy relative to another, and the resilience generates a torsional force. 16. A toothbrush according to claim 15, wherein one or more of the said torsion parts comprises a first part extending radially from the rotation axis, and the other part comprises a second part located upon the arc followed by the first part during the relative rotation, such that the first and second parts bear upon each other during the relative rotation. 17. A toothbrush according to claim 15, wherein two of respectively the first and second torsion parts are located upon the arc followed by the first or second torsion part during the relative rotation, such that the first and second parts bear upon each other during the relative rotation. 18. A toothbrush according to claim 1 characterised by co-operating end-stop means to encourage or cause the overlapping hinge parts to rotate relative to each other through a restricted angle. 19. A toothbrush according to claim 18, wherein the end stop means comprise structures which abut against each other at the limits of the restricted angle to prevent further relative rotation. 20. A toothbrush according to claim 1 wherein the toothbrush has at least two second hinge parts extending from the handle of the toothbrush toward the head, and a first hinge part extending from the neck, the said first hinge part extending between two of the second hinge parts. 21. A toothbrush according to claim 20 wherein the torsion element comprises a laterally extending torsion bar between the first and second hinge parts and integrally linking the first and second hinge parts. 22. A toothbrush according to claim 1, wherein the second hinge part has an axle integral therewith and which defines the axis about which the hinge parts are able to rotate, and the first hinge part has a bearing hole through which the axle rotatably fits or a bearing socket in which the axle rotatably sits. 23. A toothbrush according to claim 1 wherein the torsion element comprises a laterally extending torsion bar between the first and second hinge parts and integrally linking the first and second hinge parts. 5322176, 19940600, Dubach, 215/235; US-5322430, 19940600, Kasai et al., 425/003; US-5455987, 19951000, Svehaug; US-5528951, 19960600, Takahashi et al., 411/277; US-5529205, 19960600, Corney et al.; US-5568673, 19961000, Ryczek; US-5669105, 19970900, Depke; US-5743618, 19980400, Fujino et al., 362/528; US-5975693, 19991100, Malfroy et al.; US-6261499, 20010700, Okeke et al., 264/242; US-6341917, 20020100, Schubring et al., 403/296
