ABSTRACT:
An ergonomically designed toothbrush includes a handle of rectangular cross-sectional configuration. The handle is twisted about its longitudinal axis so that it fits the palm of a person's hand providing a power grip yet will fit most toothbrush holders. The forward end of the handle tapers outwardly and has an elliptical cross-sectional configuration with its outer surface being textured for ease of manipulation and comfort. A small elliptical neck connects the brush head to the handle and is designed not to interfere with the lips or cheeks when brushing. The brush head includes multi-level tufts of two grades of stiffness arranged in offset rows and is designed to remove plaque from interproximal areas as well as tooth surfaces and to reach into the gingival margin to gently massage the gums.
