ABSTRACT:
A toothbrush device that conforms to the curvature and contours of the teeth while brushing. The toothbrush device includes a handle for gripping. At least one bristle head is disposed a predetermined distance from the handle. A support mechanism is disposed between the handle and each of the bristle heads. The support mechanism varies the predetermined distance between the bristle heads and the handle as a function of a contact force applied to each of the bristle heads. A connection is disposed between each support mechanism and each bristle head. The presence of the connection enables each bristle head to move in at least one plane in a manner independent of the support mechanism. This provides each of the bristle heads with the freedom of movement needed to properly conform to the curvature and contours of the teeth.
