stannous fluoride + sodium tripolyphosphate

This is a **combination oral care agent** composed of stannous fluoride and sodium tripolyphosphate, formulated primarily for use in dentifrices (toothpastes). **Stannous fluoride** is an anti-caries and antimicrobial agent effective at preventing dental caries, reducing the viability of the oral biofilm, enhancing remineralization of hydroxyapatite in tooth enamel, reducing tooth hypersensitivity, and fighting both plaque and gingivitis[1][2][3][4][6]. **Sodium tripolyphosphate** is a polyphosphate frequently included in toothpaste as a stain control and tartar-prevention agent, chelating calcium to inhibit tartar/calculus formation and helping stabilize stannous fluoride[3][5]. This combination leverages the synergistic effects: stannous fluoride provides strong anti-caries and anti-gingivitis action, while sodium tripolyphosphate mitigates the tendency of stannous fluoride to cause staining and boosts stain removal/tartar prevention[5]. Advances in formulation have enabled stable preparations that maintain both efficacy and esthetics[3][5].
