Biofilm is a bacterial colony where bacteria can thrive and flourish. Researchers wanted to see how to break down these harmful biofilms. In this study they found, “Xylitol has a clear inhibitory effect on the formation of the experimental biofilms. This study shows that xylitol is not only efficient in inhibiting the acid production of cariogenic bacteria, but also in preventing the formation of a multispecies biofilm; it confirms the relevance of the use of this polyol for the prevention of oral diseases caused by dental plaque.”
