What role does Xylitol play in preventing caries or treating hypersensitivity?

Xylitol, is a naturally occurring 5-carbon sugar alcohol found in many fruits and vegetables. It is clinically proven to reduce plaque-forming bacteria and plaque debris and facilitate the remineralization of enamel without promoting tooth decay. Xylitol is commonly found in chewing gum, toothpaste and fluoride varnish. Its ability to enhance remineralization helps in caries prevention and reducing hypersensitivity (tooth sensitivity).
