Abstract
A toothbrush having a handle and at one end having a bristle-bearing head which is in the form of one or more segments which are flexibly and/or resiliently linked to each other. Optionally, the head may also be flexibly and/or resiliently linked to the handle. The grooves between the linked segments of the head are wholly or partly filled with an elastomeric material. In one aspect, the bristle-bearing head of the toothbrush is attached to the handle by a frame which wholly or partly surrounds the head and is an integral extension of the handle.
