The advanced Biorepair® Anti-Cavities Active Shield formula has been enhanced to combat sugar acids and cariogenic bacteria with the active action of Zinc PCA and Xylitol, alongside the microRepair® enamel repairing technology. microRepair®, biomimetic hydroxyapatite particles, bond to the enamel and protect against the erosive action of acids. Zinc PCA is the active principle that inhibits the methabolic activity of bacteria, which is the main cause of plaque and cavities formation. This advanced formula combats the formation of cavities and protects enamel every day from bacterial aggression.
