What is xylitols tooth-friendly effect?
When you use xylitol gum or mints, the acid attack that would otherwise last for over half an hour, is stopped. Because the bacteria in the mouth causing caries are unable to ferment xylitol in their metabolism, their growth is reduced. The number of acid-producing bacteria may fall as much as 90%. Since no acid is formed, the pH of saliva does not fall. After taking xylitol, the bacteria do not stick well on the surface of the teeth and the amount of plaque decreases. Research has shown that the use of xylitol gum or mints also helps correct incipient damage to the enamel. Saliva in itself protects the mouth and teeth. Saliva containing xylitol is more alkaline than saliva which contains other sugar products. After taking xylitol products, the concentration of basic amino acids in saliva may rise. When pH is above 7, calcium and phosphate salts in saliva start to precipitate into those parts of enamel where they are lacking. Thus, soft, calcium-deficient enamel sites begin to harden a
