Chewing Gum Can Be Healthy For Your Teeth.
There has been evidence of improved oral health associated with chewing gum containing xylitol, twice a day for 15 minutes.  There is a a definite increase in saliva production and flow.  This increase results in lower plaque and healthier gums.  This is particularly significant for our aging population who typically experience decreased salivary production and flow.  The resultant decrease leads to increased decay and gum disease.  Chewing sugar-free gum can add to the quality of life for the aging population.
