Burst Dental Floss Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

Oral-B is the best-performing burst dental floss brand in July 2026, moving 200,000 units across 5 ASINs for 51.3% of Top 10 volume. Amazon Basics follows with 60,000 units (15.4%), ahead of Waterpik on 40,000 units (10.3%).

With 6 brands splitting the Top 10 and 76.9% 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 $3.09 to $49.99, 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. On the growth side, B01678Y3DS leads positive momentum with ▲ 471.4% MoM growth on 4K units, with B01KZOTTSO close behind at ▲ 400.0% MoM 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
