Clinical studies have shown that chewing sugarless gum for 20 minutes following meals can help prevent tooth decay.
The chewing of sugarless gum increases the flow of saliva, which washes away food and other debris, neutralizes acids produced by bacteria in the mouth and provides disease-fighting substances throughout the mouth. Increased saliva flow also carries with it more calcium and phosphate to help strengthen tooth enamel.
Look for chewing gum with the ADA Seal because you can be sure it's sugarless. All gums with the ADA Seal are sweetened by non-cavity causing sweeteners such as aspartame, xylitol, sorbitol or mannitol. Of course, chewing sugar-containing gum increases saliva flow too, but it also contains sugar which is used by plaque bacteria to produce decay-causing acids.
