Top 20 Nasal & Oral Care Best Sellers on TikTok Shop United States — September 2026

TL;DR

Affiliate volume completely upended category hierarchy as Mouthology seized the summit, leaving entrenched leaders grappling with widespread pullbacks. In September 2026, the United States TikTok Shop nasal oral care category expanded by +13.5%, proving that broader consumer demand remains vigorous even as individual storefronts stumble. This means shopper loyalty is pivoting decisively toward trending functional ingredients like hydroxyapatite over traditional brand equity. While Mouthology took the lead and Hismile US and DR DENT defended major shares under pressure, CEELIKE & MSDRWIKEY Oral Care anchored the top four with steady daily essentials. Lower down the board, sudden surges from DR DENT tablets alongside momentum from NOBS Routines and Triquetra signal that specialized routines are actively reshaping the competitive fringe.
