Nxtrnd Mouth Guard Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

Shock Doctor is the best-performing nxtrnd mouth guard brand in July 2026, moving 5,000 units across 3 ASINs for 27.8% of Top 10 volume. LPONJAR follows with 3,000 units (16.7%), ahead of NXT NXTRND on 3,000 units (16.7%).

With 7 brands splitting the Top 10 and 61.1% 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 $8.49 to $19.95, 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, 3 ASINs forced its way in: B0018179G8 booked 2K units at $8.49, with ▲ 150.0% MoM change.

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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
