Health benefits, chewing gum
Caries
• Sweeteners—Sugar-free gum sweetened with xylitol reduces cavities and plaque by inhibiting Streptococcus mutans, a major cause of tooth decay; sorbitol, another common chewing gum sweetener, is one-third as effective as xylitol.
• Enamel repair—Some data suggest that calcium lactate reduces plaque formation and enhances enamel remineralisation when added to xylitol-containing gum.
• Chewing—Some studies attribute the anti-caries effect of gum to the chewing itself.
• Weight loss—Chewing gum leads to extra energy consumption of 11±3 kcal/hour, which would translate into a 5 kg/year loss of body fat.
