The majority of babies are born with their baby, or primary teeth, already lying in wait under the gums. Babies generally start to cut their baby teeth beginning at 6 months, according to the American Dental Association. Primary teeth may continue to erupt until age 3.
Home Remedies: Chewing gum and adding sea salt to your diet could help moderate or control excess saliva. Starting your meal with a bitter or sour food will also stimulate your digestive system, in the case of dry mouth due to inadequate saliva production.
1 Increased saliva production is especially important for people suffering from dry mouth (xerostomia) due to illness, aging or drug side effects.  Supplemental use of xylitol, in combination with other dental therapies, can reduce the incidence of new tooth decay and arrest existing dental caries.
