Yin Gum Dual Protection Toothpaste [Directly Targets Bleeding During Brushing, Provides Root-Level Gum and Enamel Protection] 1.Authoritative Dual-Efficacy Clinical Proof Clinically proven to simultaneously and significantly reduce dental plaque and improve key indicators of gum health. Results show a marked reduction in plaque index, along with a significant decrease and improvement in gum redness (bleeding, swelling). 2.Plaque Control, Repairing Gums at the Source Core ingredient Zinc Citrate disrupts the biofilm structure of dental plaque, inhibits the colonization of pathogenic bacteria, competitively binds calcium ions to block the mineralization chain and fight tartar, helps reduce oral discomfort, and promotes mucosal repair—directly targeting the root cause to repair gum redness. 3.High Fluoride Cuts Off the "Energy Source" of Caries-Causing Bacteria, Repairs Tooth Enamel The 1400 ppm high-concentration fluoride formula inhibits the growth and metabolism of caries-causing bacteria in the mouth, reduces their acid-producing capacity, and addresses the root cause of cavities. The released fluoride ions combine with hydroxyapatite in the tooth enamel to form a more stable, acid-resistant "fluorapatite" protective layer, actively repairing minor damage to carious tooth surfaces.
