Chewing sugarless gum is an accepted method of caries intervention primarily because it stimulates saliva production. Saliva plays a key role in maintaining oral health; it helps neutralize acids produced by bacteria in the mouth, remineralizes enamel, and washes away food particles. Additionally, sugarless gum often contains xylitol, a natural sugar substitute that has been shown to inhibit the growth of cavity-causing bacteria, further contributing to the reduction of caries risk.

In contrast, chewing regular gum typically contains sugar, which can promote the production of acids by bacteria, potentially leading to an increased risk of cavities. Mouthwash with alcohol can lead to dry mouth, which reduces saliva flow and can consequently increase caries risk. Eating sticky candies is also detrimental, as they can adhere to teeth and provide a prolonged sugar source for bacteria, thereby promoting the development of dental caries.
