Synopsis
Source of validity: Scientific
Rating (out of 5): 3
Sodium hexametaphosphate (SHMP) is included in some oral care products, particularly toothpastes and mouth rinses, primarily for its ability to inhibit dental plaque formation and reduce the deposition of tartar (calculus) on teeth. Its mechanism of action is based on its polyphosphate structure, which allows it to sequester calcium and magnesium ions. By binding these ions, SHMP prevents the crystallization of calcium phosphate, a major component of tartar. This anti-tartar effect indirectly supports the prevention of tooth decay (dental caries) because tartar can harbor bacteria that produce acids, leading to enamel demineralization.
Several in vitro and in vivo studies have demonstrated that toothpastes containing SHMP can reduce calculus formation and plaque accumulation compared to control toothpastes. However, the direct effect of SHMP on the demineralization-remineralization process of enamel (the central mechanism in tooth decay) is less clear. Most scientific evidence supports SHMP's role in reducing tartar, with secondary benefits for caries prevention due to improved oral hygiene and reduced plaque load. SHMP is often used alongside other active ingredients such as fluoride, which remains the gold standard for caries prevention.
In summary, there is moderate scientific evidence supporting the use of sodium hexametaphosphate for reducing tartar and, indirectly, supporting tooth decay prevention. Its primary benefit is as an adjunct in maintaining oral cleanliness rather than as a direct anti-caries agent.
