Oral B Io Electric Toothbrush Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

Oral-B is the best-performing oral b io electric toothbrush brand in July 2026, moving 110,000 units across 7 ASINs for 52.4% of Top 10 volume. Aquasonic follows with 60,000 units (28.6%), ahead of Philips Sonicare on 30,000 units (14.3%).

With 4 brands splitting the Top 10 and 95.2% of volume sitting with three of them, this is a concentrated shelf — the leaders hold multiple listings or one very high-velocity ASIN, so a new entrant competes against established review moats rather than an open field. Average selling prices among the leaders run from $29.95 to $39.99, which frames the price band a competing listing has to justify.

Based on July 2026 data, this shortlist surfaces the two kinds of ASIN worth keeping an eye on — the ones that just broke into the Top 10, and the ones growing fastest month over month. Specifically, one ASIN forced its way in: B0FFNJK614 booked 10K units at $13.99, with ▲ 11.1% MoM change. On the growth side, B0FQNW8V75 leads positive momentum with ▲ 1566.7% MoM growth on 5K units, with B089F7N4XF close behind at ▲ 100.0% MoM on 20K units.

The two signals carry different weight. A fresh entrant means share has already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date. A steep growth rate works as the earlier warning: it marks demand that is still compounding, usually a month or two before the ranking catches up to it.
