Reducing caries incidence

Chewing sugarfree gum can help to decrease the incidence of caries by increasing the flow of saliva in the mouth. The crucial role played by saliva in decreasing the incidence of dental caries has been demonstrated in many studies, which have found that when saliva flow is restricted or weakened in a patient's mouth, their incidence of caries may increase.
