Background
The first Oral-B toothbrush was designed and patented in 1950 by Dr. Robert Hutson, a periodontist in California. Hutson's toothbrush had soft, round-ended nylon bristles that were gentle on gums but effective at cleaning teeth. The first Oral-B power toothbrush was created in 1988 which was considered a breakthrough in technology. This marked a new era in oral hygiene and led to the introduction of the Oral-B Triumph Professional Care 9000, the first of its kind, in 2005.
Identification
The particular Oral-B Professional Care has the model number 3756.
