There are various benefits to chewing sugarfree gum, besides the fun of blowing bubbles!  Sugarfree gum can help to stimulate saliva flow.  This is a great benefit for people with dry mouth, which is a common side effect of many medications.  Sugarfree gum can also help to neutralize plaque acids.  This can help to keep the pH level in the mouth at a more favorable number.  Sugarfree gum can also help to clear food debris.  This will help to prevent decay as well as tartar build-up.  And as an added bonus, most sugarfree gums come in pleasant flavors to freshen breath!
