Toothpaste Kids Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

Crest is the best-performing toothpaste kids brand in July 2026, moving 40,000 units across 2 ASINs for 25.0% of Top 10 volume. Dr. Brown's follows with 30,000 units (18.8%), ahead of Boka on 30,000 units (18.8%).

With 7 brands splitting the Top 10 and 62.5% 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 $4.49 to $11.62, 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: B00169Z2SY booked 10K units at $3.79, with ▲ 11.1% MoM change. On the growth side, B01M9BRYDL leads positive momentum with ▲ 233.3% MoM growth on 2K units, with B0DK1VDQPC 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
