Xylitol is a naturally-occurring sweetener found in many fruits and fibrous vegetables. Xylitol is beneficial for teeth: It is anti-microbial and increases the pH level in the oral cavity which inhibits the growth of bacteria and plaque formation. It stimulates the production of saliva and helps to increase its protective properties, thus promoting the remineralisation of tooth enamel. Xylitol Chewing Gum is exclusively sweetened with Xylitol. It contains neither sugar nor artificial sweetener.
