Total Care Milder Taste Container
LISTERINE® Total Care Milder Taste contains zinc chloride to help reduce dental calculus thus keeping teeth whiter
Dental calculus is a deposit of calcium phosphate salts on the tooth surface. It is commonly believed to form by the mineralisation of undisturbed plaque.1,2
Calculus is porous and can act as a reservoir for bacteria and their toxins – if not managed effectively it can contribute to:
– Staining of teeth1
– Inflammation of the gingiva2,3
– Gingival recession3,4
– Periodontal disease3,4
Zinc chloride inhibits calculus formation through multiple mechanisms
Zinc ions inhibit the formation of calcium phosphate crystals and the growth of calculus by:
– Binding to calcium phosphate on plaque biofilm on teeth5,6
– Displacing calcium phosphate on the plaque biofilm5,7,8
– Inhibiting plaque biofilm growth5,9
Calculus formed in the presence of zinc ions is less crystalline, softer and less adherent to the tooth surface,5,10 and therefore easier to remove mechanically. By helping to reduce calculus build-up, zinc chloride also helps keep teeth less prone to attracting stains.
