This invention refers to a device for selective separation of toothbrush bristles that allows the toothbrush bristles to be cut into different lengths and profiles in different selected areas. According to this invention, the device ;for selective separation of toothbrush bristles comprises a base with fixation means for a toothbrush having bristles, and a support assembled over the base, wherein the support comprises a pair of simetrically pivoting stems over a first geometric plane, the support being displaceable over a portion of the base along a geometric axle that is parallel to the first geometric plane, from a resting position to a position of contact between the stems and the bristles and a cam means cooperating with the respective portions of the stems, during at least part of the displacement of the support over the base, in order to cause the symmetrically pivoting movement of the stems. Additionally, this invention refers to a device for selective cutting of toothbrush bristles comprising the above mentioned device for selective separation.
