Polyphenols
Green tea, red wine and cranberry juice contain substances called polyphenols that reduce plaque-formation and stop cavity-causing bacteria from sticking to teeth. Trials at the University of Rochester Medical Centre in the US found that drinks such as cranberry juice may help wash away up to 50 per cent more cavity-causing bacteria from the mouth. Polyphenols can also help prevent oral bacteria from producing acids that dissolve tooth enamel.
