Studies have shown that chewing gum after each meal for about 20 minutes can help prevent tooth decay. Why is this the case? When we chew gum it increases our saliva flow, in turn the saliva washes away food particles and neutralizes acids produced by bacteria. Saliva also carries calcium and phosphates, which help to strengthen tooth enamel.
Which Gum Too Choose
When shopping for gum, always look for the ADA Seal on the packaging. All gums with the ADA Seal are sweetened by non-cavity causing sweeteners such as, xylitol, sorbitol, etc. If you chew gum that contains sugar it will also increase your saliva, however, it can also increase your chances to get cavities rather than decrease it.
Brushing and Flossing
A word to the wise, don’t think that because you’re chewing sugar-free gum after each meal you don’t need to brush. It’s always recommended to brush at least twice a day and floss at least once a day.
