A brush section for an electrical toothbrush housing an electric drive, the brush section having a head portion comprising: a frame including a first plurality of contact elements supported within the frame; a movable contact element holder including a second plurality of contact elements supported within the movable contact element holder, the movable contact element holder being structured to receive a cleaning motion from the electric drive to have at least one freedom of motion relative to the first plurality of contact elements; an extension portion of the movable contact element holder arranged at a tip end of the head portion, with a gap disposed between the extension portion and the frame; and further comprising at least two bumpers disposed on at least one of the frame and the extension portion, facing toward the gap; wherein a first portion of the gap in a side periphery region of the head portion is smaller in width than a second portion of the gap in an interior region of the toothbrush head, and a third portion of the gap in an opposite side periphery region from the first portion of the gap is smaller in width than the second portion of the gap , which smaller first and third portions of the gap are formed by the at least two bumpers, and the interior region of the brush head is arranged between the side peripheries ; characterised therein that the brush section is arranged such that when a force (D) acting on the tip end of the head portion deflects the extension portion inwards, the first point of contact and therefore force transmission (T) occurs across the first portion of the gap and the second portion of the gap in the side periphery regions . a frame including a first plurality of contact elements supported within the frame; a movable contact element holder including a second plurality of contact elements supported within the movable contact element holder, the movable contact element holder being structured to receive a cleaning motion from the electric drive to have at least one freedom of motion relative to the first plurality of contact elements; an extension portion of the movable contact element holder arranged at a tip end of the head portion, with a gap disposed between the extension portion and the frame; and further comprising at least two bumpers disposed on at least one of the frame and the extension portion, facing toward the gap; wherein a first portion of the gap in a side periphery region of the head portion is smaller in width than a second portion of the gap in an interior region of the toothbrush head, and a third portion of the gap in an opposite side periphery region from the first portion of the gap is smaller in width than the second portion of the gap , which smaller first and third portions of the gap are formed by the at least two bumpers, and the interior region of the brush head is arranged between the side peripheries ; characterised therein that the brush section is arranged such that when a force (D) acting on the tip end of the head portion deflects the extension portion inwards, the first point of contact and therefore force transmission (T) occurs across the first portion of the gap and the second portion of the gap in the side periphery regions . <EOS>
