Oral-B
Robert W. Hutson (1919–2001) discovered by 1949 that thin, round-ended, nylon filaments would be gentle on the gums yet effective for cleaning teeth. Hutson patented a toothbrush in 1950. The toothbrushes were made by the Owens Brush Company. Robert Hutson also created the Oral-B brand name. Oral-B became part of the Gillette group in 1984. Procter & Gamble bought Gillette in 2005.
