Are cavities really contagious?

Yes!  According to two studies people can pass along S. mutans, the bacteria that causes cavities.  In one, the germs were transmitted between spouses who kissed; in the other, between a baby and a mother who shared food, drinks and utensils.  To stay cavity free, brush twice a day, floss nightly and visit your dentist every six months.
