Xylitol anti-cavity debate settled, says DuPont
Consuming xylitol does prevent cavities despite recent uncertainty over its anti-caries properties, according to a DuPont study.
Doubt was cast on the natural sweetener’s anti-caries effect last year when a Cochraine review declared there was little evidence. The review included data from over 5,900 subjects using xylitol-based lozenges, sweets, toothpastes, syrups, and tooth-wipes.
However, using an in vitro dental simulator with artificial saliva, DuPont believes it has proven that xylitol is protective against tooth decay because it lowered gram-positive bacteriaStreptococcus mutans (S. mutans) – a known cause of cavities.
