Harvard Health Tips
In an ideal world, you would brush after every meal. But this isn't practical for most people. Chewing gum with xylitol, a no-calorie sweetener, may be the next best thing. Xylitol inhibits the growth of mouth bacteria and reduces the production of destructive acids. How often should you chew xylitol gum? Three or four times a day. To get the full effect, chew the gum for at least five minutes.
