Which of the following chewing gums is recognized by the Canadian Dental Association as preventing dental caries?

The chewing gum recognized by the Canadian Dental Association for its ability to prevent dental caries is Trident. This recognition is based on the presence of specific ingredients in Trident that contribute to oral health, particularly xylitol, a sugar alcohol that has been shown to inhibit the growth of cavity-causing bacteria. When chewed, this type of gum increases saliva production, which helps wash away food particles and neutralize acids produced by bacteria in the mouth, thereby reducing the risk of caries.

While other brands like Orbit, Extra, and Excel may also contain sugar-free formulas and promote similar benefits, Trident is particularly noted for its endorsement by the dental association due to its efficacy in cavity prevention. This makes Trident a recommended choice for maintaining oral health in conjunction with regular dental care.
