Xylitol

Xylitol is a sweetener that belongs to a group called sugar alcohols or polyols. It is used in many sugar-free gums and candies. The ADA says sugar-free gums are sweetened with polyols such as xylitol, sorbitol, mannitol or maltitol, which are noncariogenic, meaning they do not cause cavities.

The ADA also suggests encouraging patients to chew sugar-free gum with xylitol, which can promote salivary flow and remineralization, and cannot be metabolized by cavity-causing bacteria. More saliva helps wash and buffer the mouth.

Gum does not replace brushing or flossing. Look for the ADA Seal on sugar-free gum. See oral hygiene and cavities.
