Tiny white spots very often appear on a newborn's face and gums during the first week of life. These spots are called milia (say "MIL-ee-uh").They are similar to the small white or yellow cysts that can appear on the roof of a newborn’s mouth (palate), called Epstein pearls.Milia go away by themselves in a few weeks and aren't harmful.
