A toothbrush head, connected or connectable to a toothbrush grip handle to define a head-handle length direction, with a width direction perpendicular to the longitudinal direction, is disclosed. The toothbrush head comprises a flexible bristle carrier, on which bristles are mounted, a base part closest to the toothbrush handle when connected, a longitudinally opposite tip part, and a support which supports the carrier. The support supports the carrier at the base part and at the tip part, leaving the carrier unsupported in a region longitudinally between these parts. The carrier is flexible such that it can deform under the forces of toothbrushing so that both its longitudinal and widthways sections become distorted. The support is capable of resilient bending deformation so that under the forces encountered in toothbrushing the tip part of the carrier can move resiliently to follow an arc in a plane perpendicular to the width direction.
