Tooth-friendly products are formulated using sweetening ingredients that cannot be fermented by the mouth bacteria.
Intense sweeteners such as saccharin, cyclamate, acesulfame-K and aspartame, and sugar substitutes such as isomalt, sorbitol and xylitol fall into this category.

Sugar-free chewing gums use these sweeteners. Both the sweet taste and chewing stimulate salivary flow, which contributes to the prevention of caries. Such chewing gums may also contain minerals such as calcium, phosphate and fluoride to enhance the repair process.
Studies have reported that chewing sugar-free gum after a meal accelerates the clearance of food debris and reduces the rate of caries development in children.
Tooth-friendly products have to comply with a specific test regimen in order to get ‘safe for teeth’ approval.
