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. This number is marked on the bottom or back of the handle, for example: (click to enlarge)


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, Genius, Smart, Pro, iO, AdvancePower, PlakControl, SmartSeries, DeepSweep, Denta-Pride, Black, White, Sensitive Clean, TriZone and TriAction. These names cannot be used to reliably identify your exact model of toothbrush.

Various duplicated model numbers were marked on the packaging including 2, 3, 4, 5, 6, 7, 8, 9, X, 100, 150, 400, 450, 500, 550, 600, 650, 700, 800, 900, 1000, 1500, 2000, 2500, 3000, 3500, 3900, 4000, 4500, 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 and have been re-used for completely different models.

To further confuse things, 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!

Once you have identified what toothbrush handle you have from its Type number take a look at the list of toothbrush repair guides at the top of this page.

Can I replace the battery in my Oral-B electric toothbrush?

Yes you can replace the battery inside your Braun Oral-B, Philips Sonicare or Colgate Omron toothbrush. Use one of our detailed photographic battery replacement guides as listed at the top of this page.
