Best Mouthguard Brands on Amazon US — Top 3 Brand Sales Concentration (July 2026)
DenTek is the best-performing mouthguard brand in July 2026, moving 48,000 units across 3 ASINs for 39.7% of Top 10 volume. Retainer Brite follows with 30,000 units (24.8%), ahead of Plackers on 28,000 units (23.1%).
With 6 brands splitting the Top 10 and 87.6% 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 $13.29 to $23.99, which frames the price band a competing listing has to justify.

Trending Mouthguard 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: B09WQZCKCX booked 3K units at $9.99, with ▲ 50.0% MoM change. On the growth side, B07SKM27R6 leads positive momentum with ▲ 400.0% MoM growth on 500 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
