  • Resiliently flexible bristle bearing head toothbrush
    Patent number: 6219874
    Abstract: A toothbrush having a handle and a resiliently flexible bristle-bearing head. The head has a pair of opposing faces with the bristles mounted on one face. Each opposing face has a groove, the groove on each face being substantially parallel to the groove on the opposing face. The pair of substantially parallel grooves form a flexible hinge within the head, allowing the toothbrush head to flexibly conform from a concave profile to a convex profile to suit the labial surface of the teeth or to avoid damage to the gums.
