Key benefits

The biggest benefit of the Oral-B iO Series 3 is its focus on control.

The three modes give you a little flexibility, whether you want a standard clean, a gentler feel, or a brighter routine. The included travel case and extra brush heads also make it more convenient to use beyond the bathroom sink.
