摘要 A toothbrush is disclosed including a head with a bristle mounting surface having a center section within which an array of bundles of bristles is mounted, and a pair of bristle supports located at either end of the center section which are effective to resist bending of the bristles within the center section in the longitudinal direction in response to brushing motion so that the tips of such bristles are maintained in contact with the teeth.
