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

Oral-B is the best-performing oral b io brand in July 2026, moving 103,000 units across 8 ASINs for 59.5% of Top 10 volume. Aquasonic follows with 60,000 units (34.7%), ahead of MeaeJoto on 10,000 units (5.8%).

With 3 brands splitting the Top 10 and 100.0% 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 $12.59 to $46.23, 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: B0B69KJH18 booked 7K units at $39.94, with ▲ 16.7% MoM change. On the growth side, B0B5HTKW2K leads positive momentum with ▲ 150.0% MoM growth on 1K 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
