Collection: sp-4 toothpaste

SP-4 toothpaste appears to be a line of whitening/probiotic toothpastes sold under several labels (Eelhoe, Yayashi, NYSCPS, etc.), mostly through marketplaces like TikTok Shop, eBay, AliExpress, and smaller online stores rather than major dental brands. The marketing claims usually focus on stain removal, whitening, fresh breath, and probiotics.
