Best Tooth Floss Brands on Amazon US — Top 3 Brand Sales Concentration (July 2026)
Crest is the best-performing tooth floss brand in July 2026, moving 200,000 units across 2 ASINs for 32.3% of Top 10 volume. Oral-B follows with 140,000 units (22.6%), ahead of COSLUS on 70,000 units (11.3%).
With 7 brands splitting the Top 10 and 66.1% 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 $8.13 to $29.93, which frames the price band a competing listing has to justify.

Trending Tooth Floss Products — Growth Leaders & New Top 10 Entrants
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, 2 ASINs forced its way in: B01NBRH9TF booked 40K units at $9.97, with ▲ 0.0% MoM change. On the growth side, B01KZOTTSO leads positive momentum with ▲ 400.0% MoM growth on 10K 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
