Abstract
A toothbrush for the use of fingers to brush the teeth of infants or young children. While fingers work better than the traditional stick-type toothbrush in maneuvering around inside the mouth, the lack of vibrating/rotating in the bristle portion greatly diminished the flexibility of human fingers. Present invention provides the small-scale motion needed to rotate or otherwise move the bristle piece connected, by a flexible yet rigid cord, to a driving member, so that the brushing youngsters teeth are made more effective, resulting in better oral hygiene for infants and young children.
