Dr. Robert W. Hutson (1920–2001), a California periodontist, designed and patented a toothbrush in 1950. In 1958, he was granted a new patent for a "mouthbrush" having numerous fine, soft, flat-ended nylon bristles, and a similar appearance to the 1950 design. He claimed in his application that this brush was less abrasive to tooth enamel, better for massaging the gums, and more effective at picking up tooth powder than other brushes available at the time, which had coarse, angle-cut bristles.
Dr. Hutson sold his toothbrush business in the 1960s, and continued his San Jose periodontal practice.
