Currently around 95 percent of the world population suffer caries or perforated teeth. Three main causes of perforated teeth are Mutans streptococci bacteria, saliva, and the remaining food.

Remaining food, especially sugar which left behind in the teeth will stimulate the growth of Mutans streptococci bacteria on teeth layer. The bacteria can ferment the left sugar in the teeth and produce acid compound that will decrease the pH in the mouth to less than 5.5. Acid compound will erase teeth email layer.

Xylitol will impact on dental health because it can hinder the metabolism growth and dental plaque by Mutans streptococci bacteria. Xylitol is believed can support the remineralisation process on caries. This is said by Prof Jason Tanzer, head of Connecticut School of Dental Medicine.

Xylitol is considered as a good sweetener for tooth because xylitol prevent caries with changing the role of regular sugar. Xylitol is stated can reduce dental plaque that cannot be aparted by microorganisms that live in the mouth.

Xyilitol is the second greatest compound for dental health after fluoride, as acknowledged by Nigel Carter from the International Dental Health Foundation. Because xyilitol is empty-calorie sweetener, Mutans streptococci bacteria cannot use it as a source of energy, and even threaten the continuance of his life.

In addition, xylitol cannot be fermented so that there is no acid compound causes tooth hollow. Xylitol maintain the pH in the mouth remain stable on neutral pH (around 7) so that it can prevent the perforated teeth and stimulate production of saliva which is rich in calcium to speed the formation process of mineral layer of teeth.
