Wine could make a good antibacterial mouth wash to fight tooth decay and a sore throat, according to Italian researchers.
Professor Gabriella Gazzani and colleagues at the University of Pavia in Italy have pointed out in the Journal of Agricultural and Food Chemistry that wine can be used to combat harmful oral bacteria.
Wine has been used to treat wounds since ancient times and has antibacterial properties. The team showed that red and white wine were effective in inhibiting the growth of several strains of streptococci bacteria that are involved in tooth decay, and some cases of sore throat.
The compounds responsible for the antimicrobial activity were wine acids and red wine was found to be more active as an antibacterial agent than white. Professor Gazzani is now investigating the mechanisms by which wine can stop tooth decay and the possibility it offers advantages over standard mouthwashes.
