Identifying your Electric Toothbrush

The best way to identify the model of your toothbrush is using the “Type” number for Braun Oral-B toothbrushes, or the “HX” number for Philips Sonicare toothbrushes. The number is marked on the bottom or back of the handle, for example:

braun-oral-b-3728-professional-care-type-number

This is the easiest way to identify Braun Oral-B toothbrushes because, confusingly, Braun Oral-B have used the same various marketing and model names over the years across the whole range of toothbrushes they have produced including Professional Care, Pro, AdvancePower, PlakControl, SmartSeries, DeepSweep, Denta-Pride, Black, White, Sensitive Clean, TriZone and TriAction. They have coupled these names with various model numbers marked on the packaging including 450, 500, 550, 600, 650, 700, 800, 900, 1000, 1500, 2000, 3000, 4000, 4750, 5000, 5500, 5550, 6000, 6500, 7000, 7400, 7500, 7550, 7850, 8000, 8300, 8500, 8850, 8900, 9000, 9400, 9500, 9900 and 9950. These bear no consistent relation to the type of toothbrush they have been used to describe. To further confuse us, there are often type numbers marked on the packaging and in the instruction manuals which are different to those marked on the toothbrush handles themselves!
