Core anti caries mechanism

Inhibit bacterial acid production

Xylitol cannot be metabolized and decomposed by oral cariogenic bacteria (such as Streptococcus mutans), blocking their fermentation and acid production process to prevent tooth demineralization.

Interference with bacterial growth

The molecular structure is similar to glucose, competitively inhibiting bacterial glucose metabolism pathways and reducing plaque biofilm formation.

Promote saliva secretion

Chewing xylitol products (such as chewing gum) stimulates saliva flow, washes away food residues, and neutralizes the acidic oral environment.

Enhance remineralization

Elevated concentration of calcium and phosphorus ions in saliva accelerates mineral deposition on enamel surface and repairs early demineralization damage
