Oscillating toothbrushes
Oscillating brushes rotate a small round head back and forth, often with a pulsing movement. Oral-B's iO range uses a magnetic drive.
An oscillating-rotating brush turns a round head through a small arc, many thousands of times a minute. Some models add pulsations. The Oral-B iO range uses a magnetic drive, a display on the handle and a smart pressure ring that changes colour.
Round heads are designed for the brush they fit: iO heads fit only iO handles, while older Oral-B handles share one head fitting. Check this before buying spare heads.
