Despite paramount advancement in preventive strategies, dental caries still remains a global health problem for both children and adults. Traditionally, caries have been treated by removing the affected tooth structure and then restoring the cavities. But the focus in caries has recently been shifted to the conservation of the natural tooth structure. Using remineralizing agents is one such method of halting the caries progression at an earlier stage. Sugar substitutes like Xylitol have gained importance in preventive dentistry. The use of chewing gum carrying xylitol increases the salivary flow rate and enhances the protective property of saliva.
