Best Night Guards For Teeth Grinding Brands on Amazon US — Top 3 Brand Sales Concentration (July 2026)
DenTek is the best-performing night guards for teeth grinding brand in July 2026, moving 45,000 units across 2 ASINs for 34.4% of Top 10 volume. Retainer Brite follows with 30,000 units (22.9%), ahead of Plackers on 28,000 units (21.4%).
With 8 brands splitting the Top 10 and 78.6% 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 Night Guards For Teeth Grinding 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, one ASIN forced its way in: B0GTWHJPYR booked 4K units at $37.97. On the growth side, B07TWJLJHG leads positive momentum with ▲ 1900.0% MoM growth on 1K units, with B0BZB7LCSM close behind at ▲ 400.0% MoM on 1K 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
