Crest Pro Health Mouthwash Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

TheraBreath is the best-performing crest pro health mouthwash brand in July 2026, moving 190,000 units across 3 ASINs for 47.5% of Top 10 volume. Crest follows with 140,000 units (35.0%), ahead of Listerine on 70,000 units (17.5%).

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 $10.16 to $15.54, 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: B0758F8KDC booked 50K units at $16.97, with ▲ 400.0% MoM change. On the growth side, B0DNRJ6RP8 leads positive momentum with ▲ 614.3% MoM growth on 5K units, with B01L4ND4O0 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
