There has been a study shown and at the children dentist Mclean VA, the pediatric doctor will tell you the exact same thing. Chewing gum can actually help with tooth decay and cavities. Well, only sugarless gum can. If you get in the habit of chewing sugarless gum for 20 minutes after each meal, this will help prevent tooth decay. How is it possible that it can reduce tooth decay, right? Well, sugarless gum can help increase the flow of saliva which washed away food and other debris, neutralizes acids produced by bacteria in the mouth and provides disease-fighting substances throughout the mouth. When you have increased saliva flow it carries more calcium and phosphate, which is there to help strengthen your enamel. It is important for you to always look for chewing gum with the ADA Seal because you can be sure that you are buying sugarless gum. When gums have ADA Seal this means that they are sweetened with non-cavity causing sweeteners like other gums. The sweeteners that are cavity causing include any gum with aspartame, xylitol, sorbitol or mannitol.
Although chewing regular gum does increase saliva flow too, it also contains sugar, which builds up plaque in your mouth, which is a bacteria that causes tooth decay due to the acids. There are more effects that sugar gum can cause but research still needs to be done on this topic. It is important for you to still brush your teeth and floss regularly, do not replace that with chewing sugarless gum. It is important to still continue to brush twice a day with fluoride toothpaste and claning plaque from between your teeth at least once a day with dental floss or other dental cleaners. Remember to always buy chewing gum that is sugar free and has the ADA Seal. ADA is a criteria for safety and effectiveness.
